What Is The Weeds That Growing Over Septic Tank? (Solution)

Turf grasses are the most common plant selected for over a septic system. However, their shallow roots require frequent surface watering, and require repeated lawnmower traffic to keep the lawn trimmed. Choosing a native garden is low maintenance, requires no fertilizer, mowing, or watering.

• Creeping Charlie, stonecrop, and jewelweed plants will multiply and cover a septic space nicely. Perennials and grasses (including ornamental grasses) work best around your septic tank and drain field. Their shallow root systems are less likely to invade the underground system and cause it damage.

How do I get rid of weeds in my septic field?

Spray the Roundup onto the weeds over the leach field, wetting the leaves’ top and bottom with the solution. Avoid spraying any desirable plants as Roundup kills all vegetation.

Why is the grass above my septic tank?

When you notice brown patches or lines over your septic system, it’s likely that the soil under the grass isn’t getting enough water. When it’s hot and sunny, the shallow soil can dry out quickly, keeping your grass from getting the moisture it needs.

How do you tell if the leach field is clogged?

Stay vigilant for five signs your drainfield does not drain correctly anymore.

1. Slowing Drainage. Homeowners first notice slower than usual drainage from all the sinks, tubs, and toilets in a home when they have a compromised drainfield.
2. Rising Water.
3. Increasing Plant Growth.
4. Returning Flow.
5. Developing Odors.

How long do septic leaching fields last?

It’s important to consider the life expectancy of a drain-field, too. Under normal conditions and good care, a leach-field will last for 50 years or more. Concrete septic tanks are sturdy and reliable but not indestructible.

Can you put mulch over septic tank?

Gardens. Landscape fabric, plastic, bark, or mulch should not be used over your septic system. These materials reduce air exchange while bark and mulch also retain excess moisture. Adding more than a few inches of soil over the drainfield, such as for raised beds, limits air exchange and can lead to compaction.

Should I mow my leach field?

No. Ride-on mowers and other garden care equipment will not harm your leach field. You should, however, stay away from it with cars, pick-up trucks, and rubber tired heavy equipment like backhoe loaders.

Why is my grass dying over my leach field?

As temperatures increase, grass draws more moisture from the soil beneath it. The soil above leach lines is shallower than the soil in the rest of the lawn, so it holds less water compared to the rest of the lawn, causing grass directly above the lines to dry out and turn yellow.

Is lawn fertilizer safe for septic systems?

Are Chemical Lawn Treatments Harmful to Your Septic System? When correctly applied, chemical lawn treatments are not harmful to your septic system. Fertilizers, pesticides, and weed killers are designed to dissolve and be absorbed by the soil and underlying root structure of your lawn.

What can you put on top of a septic tank?

Put plastic sheets, bark, gravel or other fill over the drainfield. Reshape or fill the ground surface over the drainfield and reserve area. However, just adding topsoil is generally OK if it isn’t more than a couple of inches. Make ponds on or near the septic system and the reserve area.

How much does it cost to clean a leach field?

Leach field ¹ rejuvenation costs between $1,500 and $5,000. This method is used to clean leach fields that have become clogged or soaked with wastewater and solid waste.

Can a leach field be restored?

A drainfield that isn’t working properly could result in clogged drains and the release of raw sewage on the ground’s surface. A failing drainfield can, and should, be restored quickly to avoid permanent damage. Biological, organic, and inorganic additives can be used to restore functionality to a failing drainfield.

How far down is a leach field?

A typical drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36 inches.

What is the average life expectancy of a septic system?

Age of the System It’s pretty common for a septic system to last 40 years or longer, which means if you buy a new home, you might never need to replace it. However, you might have an older home whose septic system has been in place for nearly half a century.

How often should you pump your septic tank?

Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.

Can a drain field be repaired?

There’s usually no repair for a drainfield that has failed. You probably need to replace some or all of your system.

Safe Plants to Grow Over Septic Tanks & Drain Fields

When some trees and bushes are planted near septic tanks and drain fields, their vigorous roots can cause harm to the tanks and drain fields. Find out which plants are the most dangerous to cultivate near a septic system and which ones are the safest.

Plants Safe to Grow Over Septic Tanks and Drain Fields

Keep in mind that you should not become so concerned about the possibility of root damage to septic systems that you avoid planting in these places completely. It is not only permissible, but really desirable, to cultivate the appropriate kind of plants in this location. Plants will help to prevent erosion and will also help to absorb some of the surplus rainwater from the drainage system. Growing tall fescue grass, Kentucky bluegrass, or other lawn grass over that section of earth should be the bare minimum solution to the problem.

Plants such as creeping Charlie, stonecrop, and jewelweed will proliferate and cover a septic area effectively.

Because of their thin root systems, they are less prone to infiltrate and destroy the subsurface infrastructure.

It goes without saying that there are several instances of such plants, so you will want to limit down your options.

• If the location is sunny, try planting one of these 10 great perennials for sunny locations: However, if the location does not receive much sunlight, you will most likely be pleased with these shadow garden plants. Septic tank drain fields have soil that is sometimes wetter than usual, sometimes saltier than average, and sometimes a combination of the two. Make sure to cover both bases with perennials that can withstand both damp soils and salt, such as bee balm, hollyhocks, and wild violets. When it comes to plants growing over septic systems, deer will not turn their noses up at them
• Therefore, if you have a problem with this large pest eating your plants in your area, you will want to consider deer-resistant perennials and deer-resistant ground covers, as well as spring bulbs and ornamental grasses that deer do not eat

It is not safe to consume food crops that have been planted in the ground near a drain field since doing so may result in the consumption of hazardous microorganisms. It is preferable to plant shallow-rooted trees and bushes around septic tank drain fields if you must plant trees and plants. The Spruce is an example of a shallow-rooted tree or shrub. K.

The Worst Plants to Grow Over Septic Systems

Planting huge, fast-growing trees is often discouraged. However, some of the greatest offenders are trees and shrubs with root systems that are aggressively seeking out sources of water, which makes them particularly difficult to control. They are not picky about the water source from which they draw their water, which means the pipes in your septic tank drain field are completely fair game. Weeping willow trees are a well-known example of this. There are several trees and bushes to avoid, however the following are only a few examples: If you have avoided planting any of the most dangerous plants right over your septic tank drain field, you should still be concerned about the consequences.

Any huge, mature trees that may be growing in close proximity to your septic system continue to pose a threat.

As a result, a mature specimen 50 feet tall should be at least 50 feet distant from the viewer.

In the event that this is not practicable, root barriers can be installed to try to prevent tree roots from accessing your septic drain field (similar to the bamboo barriers used incontrolling invasive bamboo). The Spruce Tree K. Dave’s / K. Dave

The Basics of How Septic Systems Work

Septic systems are used to treat wastewater in rural regions that do not have access to sewer systems. An underground, waterproof container, the septic tank is where wastewater from your toilets, showers, sinks, and clothes washer is stored after it has been removed from your home via a pipe. Solids (sludge) and scum are separated from liquids in a septic tank, which is intended to do this. Solids sink to the bottom of the container. The slime rises to the top of the heap. The liquids create an intermediate layer between the scum and the sludge, separating them from the other two layers.

1. The introduction of more wastewater from the residence serves as a stimulus for their expulsion.
2. Upon discharge, liquids are channeled into a much bigger portion of the septic system known as the “drain field,” “leach field,” or “leach pit.” Typically, a drain field is composed of a number of perforated PVC pipes that are installed in subterranean trenches.
3. Drain field cloth can be used to protect dirt from getting into the holes.
4. “Percolation” is the term used to describe how wastewater moves through the earth.
5. The evaporation of excess moisture from the soil will take care of any excess moisture unless you (inadvertently) do something to hinder it.
6. The Spruce / written by K.

Planning a Septic Field Garden

When it comes to planting near septic tanks, the drain field pipes are the most important thing to consider. If roots penetrate the perforations and clog the system, it is best to remove them immediately. All of the components of this meticulously calibrated system must be in good working order, or else the consequence is a complete disaster (and a costly one). While annual flowers such as impatiens are shallow-rooted enough to be used as septic-field plants, the fact that they must be replanted every year makes them less than ideal for this purpose.

If you are digging in a drain field, you should always wear gloves to protect your hands.

All of the following are terrible ideas because they may interfere with the regular evaporation process, which is responsible for removing excess moisture from the environment:

• Increasing the amount of soil in the region Using excessive amounts of mulch
• Providing more water to the plants than is strictly necessary

Growing Over Septic Tanks: Choosing Plants To Grow On A Septic System

Liz Baessler is the author of this piece. Septic drain fields are a challenging landscape design challenge. They frequently cover a big area of ground that would appear weird if it were left uncultivated. In the case of a property with a lot of shade, it can be the only sunny spot accessible to you.

In a dry area, it can be the only place where there is any moisture. On the other hand, not everything that may grow on a septic drain field is considered safe. Continue reading to find out more about selecting plants that are compatible for septic systems.

Growing Over Septic Tanks

What is a septic drain field, and how does it work? Basically, it’s a more environmentally friendly alternative to sewer systems, which are typically found on rural estates. A septic tank is a device that separates solid waste from liquid waste. Liquid waste is transported underground through long, broad, perforated pipes that are buried deep into the ground. The wastewater is discharged gradually into the soil, where it is broken down and cleansed by bacteria before finally reaching the groundwater table and entering the water supply.

It is critical, however, to select the appropriate plants for growing on a septic system.

Septic Field Plant Choices

Whether or whether it is safe to produce vegetables on a septic field is a matter of disagreement. Root vegetables should be avoided at all costs, and mulch should be laid down to prevent wastewater from splashing up on leaves and fruit throughout the growing season. Really, if you have another location where you can grow your veggies, it is preferable to do it there. Flowers and grasses are a better option than shrubs. Due to the fact that the perforated pipes are typically 6 inches (15 cm) below ground, plants that are suitable for septic systems have shallow roots.

If possible, consider plants that require little maintenance and don’t need to be divided every year – this will assist to decrease pedestrian traffic.

• Butterfly weed, Sedum, Lily of the Nile, Tulip, Daffodils, Hyacinth, Crocus, Foxglove, Black eyed Susan, Primrose, and more flowers

When planting on a septic drain field, restrict digging to a bare minimum and use gloves at all times to avoid contamination. This page was last updated on Learn more about Flower Garden Maintenance in General.

Revegetate Your Leach Field

Suzy Crowe, Master Gardener, contributes to this article. Whatever the situation, whether you have an existing leach field or are building a new one, keeping the leach field devoid of plants can cause major difficulties very quickly indeed. It is beneficial to plant a leach field because it helps the system work correctly, improves the appearance of a big open space, and prevents noxious weed growth. Understanding how a leach field functions will assist you in deciding what, how, and when to plant.

1. All of the drains in the home run to a purification tank.
2. In other cases, if the soil in the field is clay or compacted, your pipes are clogged, or your system is otherwise not functioning correctly, the effluent may not drain as efficiently.
3. As far as planting on a leach field is concerned, provided the system is functioning correctly, the effluent should not be an issue.
4. If the effluent is not allowed to percolate correctly, it may come to the surface and contaminate the surrounding soil.
5. The soil in leach fields may also be very alkaline, not just as a result of the effluent, but also as a result of the fact that many domestic cleaning products include alkaline ingredients.
6. Before you start planting, you should get your soil tested to see if there are any issues with the soil.
7. So, what kinds of plants are appropriate for use in a leach field?

Trees and plants can choke drainage pipes, causing your system to become unable to work properly.

Growing vegetables in a raised bed is also not a smart idea.

Standard perennials are not always a poor choice, but they may require more attention than you would want.

Choosing a natural grass and wildflower mixture is the best option.

They require minimal care, and their quick spread allows them to cover a vast leach field in a short period of time.

Make certain that any existing weeds are removed before seeding in order to start with a clear slate.

Sow the seeds by hand if possible.

After you’ve tilled the dirt around the seeds, cover them with it.

Covering the plants with a thin layer of mulch will aid in water retention and also keep animals away.

Controlling a weed problem before it develops is far easier than removing a weed problem once it has developed in your yard.

By putting in the time and effort up front, you can avoid potential complications down the line.

My septic system was constructed and vegetated the following fall, only to discover that when the seeds germinated the next spring, so did all of the weed seeds that had been dormant for a whole season.

After one aching back, the existing weeds were completely eliminated before they could go to seed. However, if I had planted vegetation in my leach field during the first season, I would have spared my back. The lesson of the story is: save a back, destroy a plant.

How to Use Roundup on Leach Fields

It is the leach field of your septic system that filters the wastewater from your house, and it is the final stage in the process. If weeds have taken over the field, you may destroy them without having to dig into the soil, which is a nice alternative to digging into the soil. A glyphosate-based chemical, such as Roundup, destroys weeds and everything else in its path, even down to the root system. While ready-to-use weed control treatments are available, spraying a Roundup concentrate is a more cost-effective way to deal with the weed infestation.

• A bright and windless day with temperatures over 60 degrees Fahrenheit should be used as a guideline.
• Roundup concentrate is poured into a hose-end sprayer, and the dial is adjusted at 6 ounces per gallon of water.
• Spray the Roundup solution over the weeds in the leach field, making sure to wet the leaves on both the top and bottom of the leaves.
• Wait up to two weeks to make sure that all of the weeds have died before continuing.
• Although some plants are quite robust, some require more than one application of glyphosate, the active component in Roundup, to ensure that they are completely eradicated.

Landscaping Around a Septic System: Do’s and Don’ts

Riverside, California 92504-17333 Van Buren Boulevard Call us right now at (951) 780-5922. A big number of large plants, patios, and other structures are likely to be absent from the region surrounding your septic system. Indeed, conventional thinking is that you should avoid both large landscaping and septic systems in the vicinity of one other. This is a reasonable guideline to follow since roots can entangle themselves around pipes and cause them to burst. Plants, on the other hand, can absorb excess rainfall and decrease erosion, so landscaping around your septic system might not be such a bad idea after all.

You don’t want roots to penetrate the perforations and clog the system, so keep them out.

Landscaping Do’s and Don’ts

• Plants that do not require a lot of water should be used. This stops plant roots from looking for water and interfering with your system’s functionality. Make use of herbaceous plants with shallow roots, such as flowers and ground cover. When planting quarts, gallons, or plugs, make sure to keep your plants somewhat near to one another to prevent erosion. This will help restrict the growth of weeds. If you have any trees or shrubs growing in your yard in the future, consider how their development may impede access to the septic tank lids, leach field, and sprinkler system. Using a potted plant, riser cover, or lawn ornament just above your access hatch, you may mark the position of your access hatch. When it comes time to dig it up, it will be much simpler to do so. Allow tall Kentucky bluegrass or another type of lawn to grow over the plot of ground that serves as a septic tank cover. Consider the benefits of growing perennials. Because both grasses and perennials have a shallow root structure, they should have no negative impact on your tank or drain field. Make use of tiny, non-woody groundcovers to disguise weeds. Think about planting shallow-rooted trees and vegetation (such as cherry trees, dogwood trees, holly bushes, azalea shrubs, and boxwood shrubs) in the area around your septic system, but make sure they are at least 10-15 feet away from the tank.

• Get so concerned about plants and grasses hurting your septic tank that you completely demolish the surrounding region. Some grasses and plants are particularly effective at collecting excess rainwater surrounding the drain field, hence reducing the likelihood of drainage problems. Overwatering your lawn may encourage freshly planted plants to flourish more quickly. Overwatering can cause soil to contract over your leach field, which can cause your septic system to get clogged. Root vegetables can be grown in the vicinity of your system. If these nutrient-absorbing plants are planted too near together, they may cause problems with microorganisms.

• Install plastic sheeting or ponds to keep the water out. These characteristics obstruct effective drainage from the tank to the leach field. Overlook the septic tank or leach field and construct walkways and high-traffic routes
• Don’t forget that the placement of fencing and gates might have an impact on septic pumper truck access. The hoses on the truck are quite heavy, and we do not recommend that you use them to cross fences. The majority of pumpers like to have access within 50 feet of their vehicle. Planting plants or trees around the septic system is a good idea. Forestry professionals recommend planting trees 20 feet or more away from water, but trees that are known to hunt for water should be planted 50 feet or more away from water. Planting shrubs near the system is a good idea. Vegetables that are nutrient-rich can be grown on a septic system. However, contamination is a worry depending on how efficiently your soil filters microorganisms, even if it appears to be excellent for a garden. Susan Day, an expert on urban forestry at Virginia Tech, advocates planting aboveground veggies rather than root vegetables in close proximity as a safeguard. Disrupt the drainage system by constructing ponds, using plastic sheeting, or planting plants that require a lot of upkeep. Increase foot traffic in regions that are already established. The greater the amount of foot traffic, the more compacted the earth gets.

Plants Safe to Grow Over Septic Tanks and Drain Fields

As long as you choose the landscaping for the region around your septic system with care, you won’t have to be so concerned about the possibility of septic system damage caused by roots that you refrain from planting in these places entirely. It is not only permissible, but really desirable, to cultivate the appropriate kind of plants in this location. Plants will help to prevent erosion and will also help to absorb some of the surplus rainwater from the drainage system. The ideal plants to use around your septic tank and drain field are perennials and grasses (including decorative grasses).

Small, non-woody ground coverings are a wonderful choice for the same reason: they are low maintenance.

It is not safe to consume food crops that have been planted in the ground near a drain field since doing so may result in the consumption of hazardous microorganisms.

It is preferable to plant shallow-rooted plants and bushes in the vicinity of septic tank drain fields if you really must. The following are examples of shallow-rooted plants and shrubs:

• Dogwood trees, Japanese maple trees, Eastern redbud trees, cherry trees, azalea shrubs, boxwood shrubs, and holly shrubs are examples of ornamental trees and shrubs.

The Worst Plants to Grow Over Septic Systems

Planting huge, rapidly growing trees is often discouraged. However, some of the greatest offenders are trees and shrubs with root systems that are aggressively seeking out sources of water, which makes them particularly difficult to control. They are not picky about the water source from which they draw their water, which means the pipes in your septic tank drain field are completely fair game. Weeping willow trees are a well-known example of this. There are several trees and bushes to avoid, however the following are only a few examples:

• The following are examples of plants and trees: Pussywillow bushes, Japanese willow shrubs, Weeping willow trees, Aspen trees, Lombardy poplar trees, Birch trees, Beech trees, and Elm trees The majority of maple trees, with the exception of Japanese maples
• American sweetgum trees
• Ash trees
• Tulip trees

It is advised that a layer of vegetation, such as a lawn, be placed over the drain field to help hold the dirt in place and boost the effectiveness of the system. Certain principles, on the other hand, should be followed in order to avoid costly and unpleasant situations. Perhaps the greatest piece of advise would be to keep trees and bushes out of the landscaping surrounding this location. The most important factor should be the best possible functioning of your septic system, but each homeowner will need to do a cost/benefit analysis of the plants they choose on an individual basis.

If you suspect that encroaching tree roots are causing damage to your system, please contact us at (951) 780-5922 as soon as possible.

Make Sure to Choose Appropriate Plants to Grow Above Your Septic System

Have you ever given consideration to which plants should be planted where in your yard? Have you ever given any consideration to where the roots of those plants would eventually grow? Keep in mind that understanding where different utility lines and services are on your property is an important part of keeping your home safe; keep this in mind the next time you plant something in the backyard. If you are still hesitant, keep in mind that you may always request a Colorado utility locate by dialing 811.

Your Best Choices and a List of What to Avoid Planting

Because of their tenacious roots, many trees and bushes can cause significant damage in and near septic tanks and drain fields. Which plants were the most difficult to grow over a septic system, and which ones were the safest options to use?

Plants Safe to Grow Over Septic Tanks and Drain Fields

Keep in mind that you should not become so concerned about the possibility of root damage to septic systems that you avoid planting in these places completely. It is not only permissible, but really desirable, to cultivate the appropriate kind of plants in this location. Plants will help to prevent erosion and will also help to absorb some of the surplus rainwater from the drainage system. Small, non-woody ground covers and grasses (including decorative grasses) are the best plants to utilize around your septic tank and drain field because their shallow root systems are less likely to infiltrate and cause harm to your subterranean system.

Naturally, there are an infinite number of such plants to choose from, so you will want to cut down your options as much as possible. Consider the following growth conditions as a good place to start:

1. If the location is sunny, try planting one of these 10 great perennials for sunny locations: However, if the location does not receive a lot of sunlight, you will likely be happier with these shade-garden plants
2. The soil near septic tank drain fields is occasionally wetter than normal, occasionally saltier than usual — and occasionally both — depending on the season. Make sure to cover both bases with perennials that can withstand both damp soils and salt, such as bee balm, hollyhocks, and wild violets.

1. When it comes to plants growing over septic systems, Bambi will not turn his nose up at them
2. Therefore, if you have a problem with this large pest eating your plants in your area, you should look into deer-resistant perennials and deer-resistant ground covers, as well as spring bulbs and ornamental grasses that deer do not consume

The growing (and eating) of food crops on the earth near a drain field is not recommended since doing so may result in the consumption of hazardous microorganisms. It is preferable to plant shallow-rooted trees and bushes around septic tank drain fields if you must plant trees and plants. The following are examples of shallow-rooted plants and shrubs:

Weeping willow trees are a well-known example of this. There are several trees and bushes to avoid, however the following are only a few examples:

1. A variety of willow plants, including pussy willow and Japanese willow, aspen trees, Lombardy poplars, birch trees, beech trees, and elm trees
2. The majority of maple trees (apart from Japanese maples)
3. American sweetgum trees
4. Ash trees
5. Tulip trees

Consider the following scenario: you have avoided planting any of the most hazardous plants immediately over your septic tank’s drain field. Are you sure you’re out of the woods? No! Despite this, any huge, mature trees that may be growing anywhere near your septic system represent a threat to your health and safety. The basic guideline is that a tree of this size must be at least as far away from your septic drain field as it is tall — and that is the very minimum distance required. As a result, a mature specimen 50 feet tall should be at least 50 feet distant from the viewer.

Why You Have to Be So Careful Planting Over Septic Tank Drainfields

When it comes to planting near septic tanks, the drain field pipes are the most important thing to consider. If roots penetrate the perforations and clog the system, it is best to remove them immediately. All of the components of this meticulously calibrated system must be in perfect working order, or else the result will be a disaster – and a pricey one at that. Despite the fact that annual flowers are shallow-rooted enough to be used as septic-field plants, the fact that they must be planted every year makes them less than ideal.

If you are digging in a drain field, you should always wear gloves to protect your hands.

Plants in Septic Drain Fields

Property owners are advised not to put trees too close to their sewage drain lines or mounds, according to septic system specialists. Trees put out small feeder roots that infiltrate and block septic drain systems as they grow. You are, however, recommended to plant plants over the area where your septic drain is located. What you need to know about plants and your septic system is outlined here.

Septic-Drain-Field Vegetation Offers Benefits

The use of bare soil or gravel as a ground surface is not recommended for dealing with storm runoff, freezing precipitation, or severe winds. Storms and other natural forces erode the soil on the surface. Zones where water pools or excessive dirt is washed away after every storm may develop in eroded areas that are difficult to maintain. By using their roots and weight, plants help to hold the soil in place. Plant roots absorb extra water during storms and prevent the soil from being washed away by the water.

The cultivation of tall grass, weeds, and other shallow-rooted plants in the vicinity of your septic drain field is permissible, and in some cases, recommended.

Using soft, non-woody plants surrounding your septic field will assist to keep the moisture contained, while the fragile plants will allow you to easily access the components of your sewage system.

Shallow-Rooted Plants Are BestForSeptic Fields

Shallow-rooted annuals and perennials are excellent alternatives for the soil absorption field because of their shallow roots. Annual grasses and flowers die back after the first frost, which means that they will not be able to form significant roots that will clog septic lines. So that you don’t have to worry about replanting the area every spring, choose shallow-rooted annual plants that reseed readily. Perennial plants are plants that grow and blossom year after year (if the plants are flowering plants).

Among the shallow-rooted plants that can be used to grow above the soil absorption field are the following:

• Kentucky bluegrass, tall fescue, bee balm, hollyhock, wild violet, iris, tulip, and daffodil are some of the plants that grow in Kentucky.

If you want to learn more about native plants that are shallow-rooted and visually appealing, go to your local extension agent or plant nursery specialist.

Septic-Area Crops Are Unsafe for Humans

Never plant food crops in the region where your septic system’s soil absorption area is located. Septic fields treat human waste, which means that germs and disease-causing organisms are present in the soil around your septic leach field as a result of the treatment process. Produce harvested from the area surrounding your septic drain field is potentially dangerous since the vegetables may be infected with harmful germs. Do not eat blackberry or other berry plants that have grown wild over your septic field, nor should you allow anyone to consume the fruit of the bushes.

1. Other plants that should not be eaten or touched when near your septic drain area include as follows: Generally speaking, avoid eating or handling any plant-based food stuff that has been collected near the septic drain region.
2. The same level of caution should be exercised while handling ornamental flowers, blooms, and vegetation that has been harvested from the septic drain region.
3. However, the flowers may contain bacteria that you don’t want in your home or on your patio, so keep them away.
4. The presence of grasses and low ground coverings is significantly less enticing to youngsters than the presence of colorful flowers.

Some Tree Species Are Worse Than Others

In order to grow tall and robust, certain tree and shrub species require a lot of water. Hydrophilic plants are the trees or shrubs that grow in water. Hydrophilic plants are the kind of plants that are most likely to infiltrate your septic system in quest of water.

Willows, poplars, and maples are examples of trees that have root systems that are detrimental to septic systems. The roots of poplar trees may extend up to 100 feet from the base of the trees. Other tree and shrub species that might potentially infiltrate your septic system are:

• Pussy willows, Japanese willows, aspen trees, Lombardy poplar, birch trees, beech trees, elm trees, sweetgum, and ash are some of the trees that grow in this area.

Any of these trees growing in the proximity of your septic system will most likely cause root difficulties in the future. Now is the time to contact a professional tree service to remove any problematic trees for you. If you have invasive plant roots in your septic lines, your plumbing firm can power rod or hydro-jet them to clear them. They can also repair any damage to your septic lines that has been caused by invasive plant roots. In order to reduce the likelihood of future line invasions of your septic system while building a new house, avoid planting the shrubs and trees listed above in your landscaping plans.

Shrubs should be kept at least 10 feet away from the house.

Have your septic lines examined and fixed as soon as possible.

Is it okay to plant a garden over a leach field?

Planting over a septic leach field (drain field) is possible, but it must be done with caution to avoid contamination. If you just have a little amount of garden area on your home, the leach field may be the only place you can plant flowers or vegetables. Growing shallow-rooted plants over the drainage region is advised since they aid in the removal of surplus moisture and nutrients from the soil as well as the reduction of soil erosion. A range of different herbaceous perennials, annuals, and groundcovers can be safely and efficiently planted in addition to turf grass, which is the most common choice.

About Septic Systems

The majority of residences in rural regions, where city sewer connections are not readily available, have their own septic systems, which are comprised of a septic tank and a leach field. The septic tank decomposes organic matter and removes oil, grease, and particles from the waste water generated by a home. Septic tank effluent is released to an underground network of perforated pipes, which allow the liquid to gently flow back into the surrounding soil. Water that percolates through the soil and into the water table in a well working septic system is free of hazardous bacteria and nutrients before it reaches the water table.

Planting Considerations

Planting over a leach field requires special care since plant roots can block drain pipes and cause damage to the drain field, which can be a costly problem to repair after it has occurred. Several herbaceous perennials are relatively risk-free choices since their roots will not grow deep enough to reach the sewer lines. Because they require less irrigation and because their roots will not seek to penetrate the continually moist soil around the drain pipes, drought resistant plants are favored.

1. Additional considerations include minimizing the quantity of water supplied over the leach field, since saturated soil can inhibit effluent evaporation and increase the likelihood of groundwater pollution.
2. Solid woody plants have deeper roots that have the potential to clog drain lines in a very short period of time.
3. Planting a tree towards the end of the drainage line, where there is less water to attract the roots in the direction of the leach field, is an option if you absolutely must.
4. The roots of a tree will normally reach at least as far from the trunk as the tree’s height from the ground.
5. The detergents and cleaning chemicals that are flushed down the toilet are often alkaline, and this can cause the pH of the soil to rise over time.
6. Furthermore, residential effluent typically contains significant quantities of sodium, particularly if you use a water softener.
7. It is not a good idea to plant vegetables over a leach field.
8. A further consideration is that many vegetable gardeners are apprehensive about growing their food plants on soil that is regularly contaminated with household pollutants.

Unfortunately, building raised beds over the drainage region is also not a viable option. The increased soil depth created by the beds may reduce evaporation and reduce the effectiveness of the septic system’s efficacy.

Receive Notifications As you go about your daily pumping rounds, you’ve seen the many different ways that homeowners may sabotage their septic systems by using bad landscaping or making other ill-informed land-use decisions. When the driveway becomes overcrowded, people park their automobiles on top of the septic system. They build a wooden deck over the septic tank, making it difficult for you to get to it.

1. They promote root infiltration, soil compaction, and broken and damaged drainlines, and then wonder why they’re having trouble maintaining the septic tank.
2. On Bowen Island in the British Columbia province of Canada, there is a landscape and garden designer by the name of Wynn Nielsen.
3. A presentation on landscaping around a septic system was recently prepared by Nielsen to assist disgruntled property owners – who may not be aware that they have a septic system or who may not even be aware that they do have one – who are confused about how their system operates.
4. In Nielsen’s experience, landscaping designers are often late to the game when properties are being developed, because landowners have formed preconceived views about how they want to use their lots before the designers arrive.
5. According to her, “septic fields tend to occupy the most appealing portions of a lot, and people tend to want to utilize them.” “People want to build patios, decks, and hot tubs on their properties.
6. I’m the one who has to break the terrible news to you that you won’t be able to accomplish that without causing damage to the septic field.
7. “It would be wonderful if there were greater awareness of the end-user.” The majority of pumpers are gearing up for the start of the hectic season.
8. Some of Nielsen’s presentation may be useful in explaining how each planting option might affect the effective usage and lifetime of a customer’s septic system to them in your presentations.

Additionally, Nielsen has these words of wisdom for septic pumpers and installers: If homeowners have a lot of questions and worries regarding their landscaping, they should not be shy about calling in an expert.

STEER CLEAR OF THESE

Your knowledge of the first guideline of planting around a septic system includes knowing to avoid thirsty plants that have deep roots. Water-loving trees such as willows, birch, silver maple, elm, beech, walnut, and linden, according to Nielsen, should be kept at a safe distance from homes. The use of aggressive, dense ground coverings that will interfere with the evaporation process, such as pachysandra, cotoneaster and periwinkle, is discouraged, according to her. Others to stay away from because of their aggressive roots include vines and wisteria, as well as bittersweet, morning glory, campsis, and hops.

• Any species of bamboo
• Any plants with very strong lateral root development
• Any other trees with a particularly strong lateral root growth Pond grasses that thrive in water and grow in vast quantities
• Clematis native to the area (self-seeding)
• Cedars (with the exception of genetic dwarfs)
• Vinca stolonifera

Prairie grasses and meadows can be no-mow and can prevent driving across septic fields, both of which are beneficial characteristics, leading some people to believe they are desirable. Nielsen, on the other hand, believes that they are frequently poor alternatives for the septic field. The prairie grasses and perennials contain some of the longest, tangliest, and strongest roots on the planet, according to Dr. Smith. Prairie grasses have vigorous roots that are good at searching out water sources such as perforated drainpipes as a result of their drought-resistant characteristics.

• While cedars are beautiful, they may be a nuisance when they grow next to a septic field.
• When homeowners insist on planting trees with significant lateral root development, encourage them to take a deep breath and wait.
• The owners of landscape-intensive yards must be cautioned not to plant vegetables over the septic field as this might cause serious problems.
• They are cautioned, however, that disturbing the soil with these annual crops is detrimental to the septic system, and that the wastewater may include diseases that can be transmitted to the edibles.

GO AHEAD AND PLANT THESE

While typical lawns are permitted for use over septic systems, Nielsen notes that many homes are moving away from that type of ground cover that requires a lot of upkeep and requires a lot of water.

She cites a few grass kinds that are commonly considered to be superior than others. Alternatives that are less risky include:

• Eco-grass and fescues that have been pre-mixed
• The tufted fescues, the feather grass, the pennisetum, and the deschampsia are examples of small grasses. Plants that look like grass, such as mounding mondo grass, liatris, liriope, and armeria

“Lawns are not particularly environmentally friendly. Most animals do not thrive in them, but we still have children and dogs, who enjoy running about on them,” she explains. “They are also a terrific location for youngsters to play.” As an alternative to standard lawns, Nielsen advises drought-tolerant plants with short, fibrous root systems that are hardy in your area and can thrive in both sun and shadow situations, depending on the situation. Her top recommendations include the use of microclover/ecograss/carex pensylvanica dwarf, the introduction of white clover, carpets (thyme, sedums, low-growing ground coverings), shallow, short/soft rooted perennials, bulb/corm/rhizome/tubers in lawns, and moss in the landscape.

Another option for adding interest to the landscape without putting the septic system at danger is to intersperse annuals or bulbs throughout the ground cover, according to Nielsen.

Furthermore, the newer dwarf tree and shrub kinds do not pose the same threat as their larger counterparts.

Fibrous root systems are found in a variety of shrubs including boxwood, potentilla, daphne, and choisya, as well as the euonymous and hebe.

CONSIDER LAND USAGE

Most of the time, homeowners employ Nielsen to design a landscaping plan after a site has been created and a home has been constructed. Developers and septic installers, on the other hand, should incorporate a landscape designer earlier in the process in order to ensure the greatest possible use of the site, according to Nielsen. According to Nielsen, the position of the septic field is frequently dictated by the land’s topography, and it is typically the flattest, sunniest section of the property that is also the greatest location for intensive horticulture.

“These choices have a negative impact on their capacity to use property that they have paid a lot of money for, which is unfortunate,” Nielsen adds.

They aren’t considering how the homeowner will wish to make use of the property while making their decisions.

My task would be a lot simpler if I had done a bit more planning ahead of time. Nielsen hopes to educate residents about septic systems and perhaps preserve a few septic systems as a result of her landscaping presentation and getting to know the pumping specialists on Bowen Island she is visiting.

Septic System Tips

In order to extend the life of your on-site sewage system, save maintenance expenses, and safeguard water quality, you should do the following:

1. Annually inspect the tank in your septic system. Septic tanks should be pumped out on average every 3 to 5 years, depending on usage. It is possible that an inspection by you or a professional will reveal that you need to pump more or less often. Pumping the septic system on a regular basis guarantees that sediments do not flow from the tank into the drainfield. It is possible for solids to ruin a drainfield, and pumping will not restore a failed drainfield to operation. Reduce the amount of water you use. Reducing the quantity of wastewater that enters your on-site sewage system may help to extend the life of the system. Excessive water consumption is the most common cause of system failure. To minimize water use in the home, do the following:

• Showers, toilets, faucets, and other bathroom and kitchen fixtures that conserve water should be used. Ensure that each appliance, such as a dishwasher or washing machine, is run and drained individually. Fix all leaks from faucets and toilets as soon as possible. Spread out your laundry throughout the course of the week and avoid doing incomplete loads

Water from downspouts and roofs should be directed away from the drainfield. It is possible that additional water from these sources will interfere with the effective operation of your drainfield. Keep automobiles and trucks away from septic systems. Tank Drainfields are a type of drainage system. This helps to keep pipes from breaking and dirt from being compacted during the construction process. Compacted soils are incapable of absorbing water; thus, phosphate-free detergent should be used.

System Don’ts

Keep the following points in mind to ensure that your on-site sewage system is in perfect functioning order:

1. Use of Garbage Disposal Should Be Limited A trash disposal increases the amount of particles and grease in your system, which might cause drainfield failure. Use of septic system tank additives or “miracle” system cleaners is not recommended. Because they enable sediments to flow into and clog the drainfield, some of these chemicals can actually cause damage to your on-site sewage system. Ground and surface water can be contaminated as a result of the chemicals. In Bethel, OH, Septic Systems Tank is a company that provides Septic Systems Tank services. Water from hot tubs should not be flushed down the toilet or into the onsite sewer. Massive amounts of water are detrimental to the system, and chlorine can eliminate vital microorganisms that are present in the water. Ensure that hot tubs are drained onto the ground and away from the drainfield, rather than into a storm drain. Solid wastes should not be flushed into the on-site sewage system. Diapers, cigarette butts, coffee grounds, tampons, condoms, and grease are examples of such waste. It is not advisable to flush strong chemicals down the toilet, including cleaning products. Using household chemicals, such as drain cleaners, paint thinners, and floor cleaners, can destroy vital microorganisms in your septic system tank, contaminating ground and surface water. Don’t build patios, carports, or use landscaping plastic over the drainfield to keep it clear. It is recommended that you plant grass around your septic tank and drainfield to keep them covered. The compaction of soil and the paving of roads prevents oxygen from reaching the soil. It is necessary for bacteria to break down and purify sewage in order for them to thrive.

Landscaping Your Drainfield: QuestionsAnswers

Your drainfield represents a significant financial commitment. Treating it properly and keeping it from harm may save you a great deal of time, effort, and money over time. Our septic system tank service is available to assist you in extending the life of your system.

1. What may I plant in the area around my drainfield? Drainfields benefit greatly from the presence of grass. Grasses can be used as a decorative plant, groomed in a standard lawn, or left unmowed in a meadow setting. Alternatively, groundcovers and ferns can be used (see questions 11 and 12 for more details). The secret to successfully planting over a drainfield is to use shallow-rooted plants that require little upkeep and consume little water. It is important to remember that if your tank covers are covered, the plants that grow over the tank – from the intake to the exit – will need to be removed every 3 to 4 years for inspection and pumping
2. What is the maximum distance that trees and plants can be from the drainfield? Maintain a minimum distance of 30 feet between your drainfield and any trees or heavy vegetation. If you do decide to plant trees near a drainfield, you should speak with an expert to explore your options and requirements beforehand. In most cases, trees and bushes have vast root systems that seek out and develop into moist regions, such as drainfields
3. However, this is not always the case. Is it permissible to grow a vegetable garden over my drainfield? No. The practice of growing vegetables over a drainfield is discouraged. Watering vegetables is necessary, because too much water in the soil diminishes the soil’s capacity to handle wastewater. Some plants have strong roots that might cause damage to drainfield pipes. It is also possible to damage pipes during bed preparation, such as rototilling or extensive digging. What do you think about using landscaping plastic or cloth under the mulch? No. The use of plastic in the drainfield soil limits the essential air exchange. Even spreading mulch or bark over the drainfield is not suggested due to the fact that it hinders air circulation and absorbs moisture. Is it possible to construct a carport or camping pad over the drainfield? Perhaps a tennis court or a relaxing hot tub would be wonderful. No, for a few of reasons. It is important to avoid driving over the drainfield since pressure from automobiles and heavy equipment compacts the soil and can cause pipes to get damaged. Second, impermeable materials such as concrete and asphalt restrict the amount of water that evaporates and the amount of oxygen that is available to the soil. The proper decomposition of sewage by soil microorganisms is dependent on the presence of oxygen. What do you think about building my carport over the replacement space? No. There should be no development or compaction in the authorized drainfield replacement area (reserve area). Is it okay for cattle to graze on the drainfield? Is it really only one horse? It is recommended that livestock be kept away from drainfields. During the winter, cattle tramples and muddy the soil
4. During the summer, they compress it even further. As previously stated, this is detrimental to the soil’s ability to exchange oxygen. Please accept my apologies
5. Even one horse is not suggested. My drainfield receives rainwater that is directed there. Is this an issue for you? Yes. It is recommended that downspouts and rainwater runoff from hard surfaces such as driveways and patios be directed away from the septic system tank and drainfield. A shallow trench uphill from a drainfield can assist in diverting water away from the drainfield. Is it possible to construct a sprinkler system in close proximity to the drainfield? It is recommended that water lines be at least 10 feet away from all components of the septic system. Make certain that all sprinkler lines are equipped with certified backflow prevention devices
6. . and may I build a retaining wall and install drains in the area behind the house? You should never cut through a drainfield to install drains (interceptors, French drains, curtain drains, or retaining walls) or to install retaining walls within 30 feet of any part of the septic system. French drains are renowned for transporting pollutants from septic systems into bodies of water or streets
7. All right, you’ve told me everything I’m not allowed to do. Can you tell me what I can do to make my drainfield seem more appealing? Growing plants for your drainfield will be very different from any other landscaping experiences you may have had previously. First and foremost, it is not advisable to work the soil, which means that no rototilling should be done. Some sections of the system may be barely 6 inches below the surface of the ground. Adding 2 to 3 inches of topsoil should not be a problem, but adding more may cause problems. Second, the plants must be low-maintenance and water-intensive in order to be effective. If you choose plants for your drainfield that, once established, will not require regular watering, you will be in the greatest position. What can I do to make the drainfield area appear more natural? A meadow that has a mixture of natural grasses and shallow-rooting flowers may be both visually appealing and beneficial to animals. The use of wildflowers and bulbs to design the drainfield is a simple approach to provide 2 to 3 seasons of color while still being minimal maintenance. Bulbs such as daffodils and crocus are easy to naturalize, and both are drought tolerant and perennial, meaning they will come back year after year.

When selecting wildflower seed, there are several important considerations:

Check to check that the seed is still alive and not a remnant from the previous year’s harvest. Many of the mixtures now available may not be well suited for our climate in the Pacific Northwest. Seed selection must be dependent on the quantity of sunlight available, just as it was with the plant lists above. Most landscaping or plant wholesalers have a selection of native seed mixes that may be used in a variety of sun and shade conditions. The seed mixture should contain a combination of annual and perennial seeds.

Packets of wildflowers shipped from out-of-state may contain weeds that are considered a nuisance in our state, so be cautious when purchasing them.

If there is grass growing in your drainfield now, you cannot just put the seed over the grass and expect it to grow back.

The grass must be kept out of the area until the seed has germinated and has grown to a size that can compete with the grass for nutrients.

If we have a dry month, irrigate the seeds twice a week by sprinkling them with water.
