What Plants Can I Plant Near Septic Tank? (Solved)

If you must grow trees and shrubs, shallow-rooted kinds are better to grow around septic tank drain fields.

Shallow-rooted trees and shrubs include:

  • Dogwood trees.
  • Japanese maple trees.
  • Eastern redbud trees.
  • Cherry trees.
  • Azalea shrubs.
  • Boxwood shrubs.
  • Holly shrubs.
  • Dwarf tree varieties.

What to plant around septic tanks?

Herbaceous plants, such as annuals, perennials, bulbs and ornamental grasses are generally the best choices for use on a septic drain field. Ornamental grasses also offer the advantages of having a fibrous root system that holds soil in place, and providing year-round cover.

What can you not plant near a septic tank?

You definitely shouldn’t plant large shrubbery or trees anywhere near your septic tank. Any trees planted in your yard should be at least as far away from the septic tank as the tree is tall. For example, a 20-foot-tall tree should be planted at least 20 feet away from the septic tank.

How close to a septic tank can I plant vegetables?

While there are no specific distance mandates on vegetable gardens and septic fields, staying 10 to 20 feet outside the perimeter of your septic system’s drainage field is a safe bet for clean veggies and an effective septic system.

Can you plant above a septic tank?

Planting over a septic leach field (drain field) is possible if it is done with care. If you have limited space on your property where you can garden, the leach field may be the only spot for landscaping.

What can you put over 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.

What can you plant near sewer pipes?

The best trees to plant around your sewerage system include shallow-rooted trees and shrubs:

  • Cherry trees.
  • Japanese maple trees are among one of the few maple trees that are likely to cause less damage.
  • Eastern redbud trees.
  • Dogwood trees.
  • Holly shrubs.
  • Boxwood shrubs.

Can you plant arborvitae near septic tank?

A common hedging plant for narrow spaces is pyramidal arborvitae (Thuja occidentalis ‘Fastigiata,’ or its greener cultivar ‘Emerald Green’). From my observation, it forms a dense root mass that would run into the septic field unless contained, but could provide a decent screen with a confined root run.

Can lilacs be planted near a septic tank?

Since lilac root systems are shallow, they can only reach the base of shallow foundations. If you have a deep foundation, there is little risk of damage. If you’ve planted your lilac shrub 8 to 10 feet (2.5-3 m.) from water and sewer lines, however, there is little risk of damage, even if the pipes have cracks.

Can you put a deck over a septic tank?

You should never build a deck over a septic field; doing so will prevent the natural draining and dissipation of the effluent. This can ruin the septic system, not to mention releasing foul smells into the air all around your deck. The dissipating effluent can also rot the deck from underneath.

Can you grow a garden on top of a septic field?

The most important reason you should not install a vegetable garden on top of, or right next to, a septic system disposal field is because the plants can become contaminated by wastewater that has not yet been renovated by the field. Plants on disposal fields can absorb wastewater pathogens.

Can you plant raspberries over a septic field?

Raspberry Growing on Septic Systems Given that the drain field is in good working order, raspberries should pose no threat to a septic system. The roots of raspberry plants are fibrous and relatively shallow, with the majority of the plant’s root system contained in the first 10 to 20 inches of soil.

Can you put a greenhouse over a septic field?

A greenhouse can be erected on a septic field to grow certain types of plants. The greenhouse should not have permanent foundations, which could easily damage the septic system. Do not plant directly into the ground over a septic field, as the plants could absorb contaminants released by the system.

Why doesn’t grass grow over my septic tank?

Lawn grass species prefer moist, high pH soil, and direct sunlight. Growing grass over a septic tank can be challenging due to the acidic, low-pH soil resulting from sewage runoff into the leach field.

Can you plant shrubs on a septic field?

Avoid growing water loving plants, shrubs, and trees near your septic system. Do not grow vegetables over your septic system because of the risk of bacterial contamination and the health risks association with it.

Why is grass green over septic tank?

Greener grass over the septic tank may be the result of someone seeding that area if the tank cover was excavated for service. A backing up pipe to leachfield (or worse, a failing leachfield) could cause effluent to drain too slowly out of the septic tank or back up even into the building.

Septic Tank Care: Which Trees to Plant Near Your Septic System

The addition of trees, bushes, and other plant life may improve the overall look of any landscape, but it is important to exercise caution when planting anything near a septic system. In our last article, we discussed which portions of your septic system are most sensitive to tree-root damage, as well as how far away you should place your trees from the septic system’s perimeter. The moment has come to take a look if you haven’t already done so. The trees, shrubs, and other plants that are safe to plant near your sewage system and the trees and shrubs that you should avoid growing anywhere near your septic system will be discussed today in detail.

Why might it be beneficial to plant vegetation near or over your leach field?

Several homeowners have become so anxious about the prospect of planting trees, bushes, or anything else in their leach field that they avoid doing it entirely. Although it may seem counter-intuitive, growing the appropriate sort of plants may be good to the health of your septic system. This is due to the fact that plants aid in the prevention of erosion by eliminating excess moisture from your leach field.

Which plants are safe to place near or over your leach field?

Planting plants with shallow root systems, such as grasses, annuals, and perennials, is your best hope for preventing soil erosion. Spring bulbs, wild violets, hollyhocks, bee balm, and deer-resistant perennials are all excellent alternatives for planting in the early spring. When it comes to planting trees and shrubs, on the other hand, you need to be a little more cautious. Planting trees and shrubs with shallow root systems near your septic system is quite safe. Here are a few examples of such plants:

  • Japanese Maple Trees, Holly Shrubs, Dogwood Trees, Cherry Trees, Boxwood Shrubs, Eastern Redbud Trees, Azalea Shrubs, and other ornamental plants

Keep in mind that you should avoid planting any plants near your septic system if you intend to eat the produce from it. It is possible that you may have better development, but none of the fruits or vegetables that are grown will be safe to consume.

What plants should you avoid placing near your leach field?

As a general guideline, you should avoid planting any trees or shrubs that are known to develop quickly and become enormous, as well as those that are known to actively seek out water sources. Other trees are more picky about the water sources they will seek out than others, and some species, such as weeping willow trees, will go for the water in the pipes that go through the leach field and into the surrounding fields. In the following list, you will find some examples of trees and plants that you should avoid planting in or near your leach field.

  • The following plants are included: Japanese Willow Shrubs, Ash and Birch trees, Pussy Willow Shrubs, Aspen trees, Tulip trees, Maple trees, Beeches, and other similar plants.

As we discussed in our last article, any trees or bushes that you plant should be placed as far away from your septic system as possible, regardless of how large they are. For example, a tree that grows to be 30 feet tall will need to be placed at least 30 feet away from your septic system in order to be effective. Our objective at Septic Remedies is to serve as your one-stop shop for all of your septic tank needs.

Landscaping Ideas Around Septic Tanks: What to Plant Over a Septic Tank

Regardless of what you’ve heard, it’s not impossible that this will happen! It is true that the correct type of plant or tree may assist the system in keeping water flowing smoothly and preventing erosion. Plants that function best have soft, green stems and are well-adapted to the amount of rain that falls in your location. In other words, we’re talking about annual plants versus perennial plants against wildflowers versus bulbs versus grass. Trees may also be used, as long as you select one with shallow roots and place it a long distance away from the tank.

Can I plant oak trees, Japanese maples or fruit trees near a septic tank?

It is possible, but it is really difficult! The roots of trees are wired to follow the flow of water. As a result, if you plant trees or bushes too close to your irrigation system, they may pry into the pipes and block them, causing harm to the system and the water flow in your home. When it comes to landscaping near the tank, the plants we described above are typically a better choice. In fact, you may cover the system with flowers like those (or even grass) to disguise the system’s presence.

Thus, white oaks and crabapples are both good choices for landscaping.

Maple trees are infamous for blocking drains and sewer lines.

Biological or viral contamination of any plants grown in close proximity to your sewage tank may be a concern.

What trees are safe to plant near a septic system?

Getting back to the original reader who sparked this discussion: because of their shallow roots, skyrocket junipers may be planted in a variety of locations. However, there is a caveat to this, as well as to all of the other options listed below. If possible, place the tree as far away from the system as the tree will be when it is completely matured. Consequently, while skyrocket junipers normally grow to be 20 feet tall, it is recommended that they be planted at least 20 feet away from the system.

  1. In zones 3-8, hemlock grows to be a beautiful evergreen that may reach heights of up to 80 feet. (Zones 3-8): An evergreen with wonderfully colored needles that may grow to be 80 feet tall
  2. It can be found in zones 3-8. Boxwood shrub (zones 4-9): An evergreen that is commonly used for hedges and grows to be around 10 feet tall
  3. It is a good choice for small gardens. Dogwood (hardiness zones 5-8): A spring-flowering tree that normally develops to be around 30 feet tall
  4. It blooms in the spring. Stunning blooming trees that grow between 30 and 50 feet tall in zones 5-8, ornamental cherries are a must-have for any garden. An added bonus is that there are several kinds and cultivars to pick from. In zones 5-9. American holly (Acer rubrum): An evergreen with vivid flashes of berries that often grows to reach around 50 feet tall
  5. It is a multi-stemmed palm that develops to be around 6 feet tall in zones 5b-11. The lady palm (zones 8-11) is a distinctive palm that may be grown to seem like a shrub and can grow to be around 10 feet tall. The pygmy date palm (zones 9-11) is a pint-sized palm that grows to approximately 12 feet tall and is extremely easy to grow.

A formal garden or an informal garden over your septic system might be challenging to design. You want a beautiful yard, but you don’t want it to come at the price of causing damage to your onsite waste water system. The majority of rural Michigan houses have an onsite waste water system (septic system), which consists of a septic tank and a water drainage field to dispose of the treated water once it has been treated. In a state with over 1.3 million septic systems, homeowners can choose to have their septic system installed in the front, side, or rear of their property, which will take up a significant amount of area in their backyard.

  1. If you follow a few simple dos and don’ts, you can keep your onsite water treatment system in good condition while still enjoying the landscape you desire.
  2. The use of just shallow-rooted flowers and grasses over the drain field will be emphasized by some sources.
  3. Another option is to choose plants that are drought tolerant so that the mound does not need to be watered as often.
  4. For the ordinary homeowner, this jumble of information can be perplexing and overwhelming.

“Big Bluestem was one of the grasses that was recommended for planting on the drain field. I believe that the root system may reach depths of up to 15-20 feet and is composed of fibrous roots. One client screamed, “That appears to be in direct conflict with the “shallow root system” suggestion!”

About septic systems

It is important to choose and arrange native plants in your landscaping with regard for their closeness to your septic system, just as you would with any other plant in your environment. Prepare yourself for the septic system by being familiar with its fundamental components before you begin working on your landscaping project. Sub-surface trench systems and mound systems are the two types of septic systems most commonly seen in Michigan. For initial separation and partial treatment, both systems contain piping that leads out of the home and into a septic tank.

  • A soil absorption or drain field is a series of ditches lined with perforated pipe that is laid on a gravel bed or a sand bed. Drain field surrounded by a three- to four-foot mound of sand elevated above ground level.

These fields are structured to drain the external water from rain and snow melt out from the field rather than into it when they are properly designed and constructed. In turn, the surface soils in the drain field become drier than those in other parts of the landscape as a result of this phenomenon. This suggests that the plants you choose for this location should be drought tolerant. Avoid having a lot of people strolling or driving through your drain field. This causes the soil to become compacted, reducing its capacity to effectively drain water.

Irrigation systems should never be installed over a drainage field.

If your drain field area is flooded, has standing water, or accumulates rainwater, it is strongly advised that you stop here and contact for a septic examination.

Choosing plants that do not interfere with septic system operations

The ability to select the most appropriate plants for a given site is essential for creating a successful landscape. When selecting native plants for over drain fields, look for ones that thrive in arid climates such as the prairie. Plant material is available in a variety of forms, including seed mixes, chosen plants, and plugs. Native plants will absorb the increased nutrients in the soil, keeping them from entering the groundwater as rapidly as they otherwise would. Aside from that, because they do not grow in water-saturated circumstances, the roots of dry prairie plants do not block sewage system pipes.

These plants are looking for extra moisture and will most likely infiltrate holes and pipes that have been left exposed.

Their thin roots, on the other hand, need constant surface watering and frequent lawnmower traffic to keep the lawn in good shape.

Making the decision to plant a native garden is low-maintenance since it requires no fertilizer, mowing, or watering. It does need some weeding and the removal of seasonal dead plants, though. As an extra benefit, it will draw the attention of butterflies, bees, and other animals to your garden.

A few choices for a short grass dry prairie, may include:

  • Wildflowers In sunny spots, plant the following forbs: butterfly weed, sky blue aster (also known as smooth aster), white aster (also known as white aster), sweet everlasting (also known as Canada milk vetch), Lance leaf Coreopsis (also known as purple prairie clover), Pale Purple Coneflower (also known as Rough Blazing Star), Royal Catchfly (also known as Royal Catchfly), Lupine (also known as Dotted Mint), Beardtongue (also Consider the following plants for shaded locations: Astilbe, Hardy Begonia, Turtle Head, Ferns, Sweet Woodruff, and Lady’s Mantle
  • And Grasses and Sedges are a type of plant that grows in a grassy or sedgey environment. Rushes include Sideoats Grama, Little Bluestem, Prairie Dropseed, Plains Oval Sedge, June grass, and Prairie Brome, among others. Shrubs Over any component of a septic system, it is not suggested to plant any type of tree. In the event that you decide to plant trees and shrubs, make sure to pick an upland type and to plant it far enough away from the drain field or mound so the dripline of the mature tree will fall outside of it. Plants that bloom in spring include: Arum, Anemone/Windflowers, Crocus (including Hyacinths), Iris (including Lilies), Daffodils, and Tulips (Note: some of the bulbs listed have been naturalized, but not all of them are native.)

Finally a few reminders:

  • Water-loving plants, bushes, and trees should not be planted in close proximity to your septic system. Growing vegetables over your septic system is not recommended due to the potential of bacterial contamination and the health hazards associated with it. It is not necessary to add more soil to your drainfield. It is necessary to have a septic examination performed if the soil in your drain field region is constantly moist or has standing water, or if you have water backing up into your home. It’s possible that your field failed
  • It is essential that you maintain a layer of vegetation over your drain field in order to keep the dirt in place and keep the system running properly. When planting, try to avoid tilling the soil too much. It is possible that you will upset or damage your drain pipes.

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. The following are examples of suitable septic field plants:

  • 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.

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.

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.

How to Plant Bushes Near a Septic Tank

Homes in metropolitan areas are often linked to the city sewage system; but, if you live in a small neighborhood with homes that are widely spread apart, you may have a septic tank to manage your wastewater treatment needs as well. Wastewater is flushed through drainage pipes and into a septic tank, where it is distributed through a series of pipes to a drainfield on the grounds of the home. While some people assume that it is impossible to plant near septic tanks, it is feasible to landscape this region if you pick plants that will not grow in such a way that they will interfere with the underground drainage pipes.

  • It is sometimes easy to identify the position of a septic tank, such as when the grass is flooded or when there is a raised sewage mound.
  • Select shrubs that don’t use a lot of water or that are somewhat drought resistant to avoid overwatering.
  • Because the septic tank and septic field are both high-moisture areas, the roots can become entangled in the pipes and potentially cause them to burst.
  • Choosing smaller shrubs instead of bigger ones is a good idea since the root systems of larger shrubs are often more extensive than those of smaller shrubs.
  • Create a landscaping plan to help you figure out where you’re going to put the plants.
  • Shady trees and bushes should be planted at the foot of septic mounds or on their side slopes.
  • Bushes placed downward absorb excess water, which helps to keep the soil atop the mounds from eroding.
  • For each shrub, dig a hole that is at least as deep as the root ball or the original planter container.
  • After planting, the roots begin to spread.

Make sure to backfill the holes with dirt, but do not cover the trunks of the shrubs with any more soil than you did when they were originally planted in their pots. Mulch should be placed around each shrub, 3 to 4 inches thick, to help in moisture management and soil compaction reduction.

What to plant near septic system? – Novice needs HELP! – Toronto Master Gardeners

(Question) I recently purchased a lakeside home in the vicinity of Kingston. The vista is breathtaking, and the tranquility is much needed. However, I am originally from Toronto and have never even attempted to mow a lawn before. I now have a mower and am doing a better job of maintaining it, but I also have a massive hill over a septic tank and a couple of bogs near drainage pipes to contend with as well. Everyone wants to assist. yet they all have different ideas about what they can do.

  1. And, on the hill, I’d want to plant wildflowers, but which ones should I choose, and how can I assure that the flowers outcompete the grass that is now growing there?
  2. I’m not sure where to begin with my gardening endeavors.
  3. (Answer)Congratulations on your major relocation!
  4. In general, your septic system may be thought of as a little wastewater treatment facility.
  5. The effluent is gently drained and evaporated from the tank through a network of perforated distribution pipes that are often installed in gravel pits (this is the septic field or leaching bed).
  6. Because these pipes must be buried at a specific depth below the surface in order to operate correctly, it is critical not to pile up too much earth on top of the drainage field.
  7. If you have marshy regions around the pipes, you may want to consult with a professional to ensure that the septic system is operating correctly, as described above.

Depending on your municipality or regional district, you may have to request it.

Plants with shallow roots, such as grasses and flowers, are the most successful to grow.

Also, avoid heavy mulching and watering the plants more than is absolutely required – all of which might interfere with the field’s ability to operate.

Lawn mixtures might differ in terms of what exactly is contained within them.

It’s a fantastic alternative to traditional lawn care.

These mixtures are referred known as ‘Envirolawns’ in certain quarters.

Within a few years, many trees grow woody roots that are more prone to clog and damage the pipes that they are attached to.

Water-seeking trees such as willows and poplars, as well as other trees with vigorous water-seeking roots, should be placed at least 15 metres (50 feet) away from the leach field. Cedars are also not suggested for use. Avoid the following items as well when working in the septic system:

  • Aspen, Lombardy poplar, weeping willow, birch, beech, elm, most maple trees, American sweetgum, ash, and tulip tree are examples of trees that grow in the area. Pussywillow and Japanese willow are examples of shrubs.

According to experts, planting any type of tree too close to a septic system is not a good idea. If you wish to plant trees near the septic tank, make sure to place them as far away from the outside perimeter of the leaching bed as feasible. Planting distances may be calculated by taking into account the height of the mature tree – for example, a tree that grows to be 25 feet (8 metres) tall at maturity should be planted at least that distance from the edge of the bed, according to this guideline.

Here are a few illustrations:

  • Dogwood, Japanese maple, Eastern redbud, and cherry trees (but not the edible kind!) are examples of trees. Azaleas, boxwood, and holly are examples of shrubs.

Planting in the marshy region you specify should be done with caution, since trees, bushes, and other plants may suffer from root rot if the drainage is poor or the area remains wet for long periods of time. Please visit the following websites for further information and reading:

Think about talking to some of your neighbours, who presumably had the same questions as you had when they first moved in and may have discovered some plants that function well in the septic system. Additionally, your town may provide you with useful information and specialists that you may consult. Discuss the finest plants for on and near septic systems with someone at your local nursery; you won’t be the first person to inquire about this! Regarding your request for a “idiot’s handbook” to rural gardening, you are off to a good start by researching what can and cannot be grown in and around the septic bed.

Always remember to research the soil, water, and sunshine needs of any plants you are contemplating growing.

Planting On Your Septic Systems, Landscaping Ideas for Your Drain Field

In the event that you want to plant over your septic drain field, When it comes to landscaping around a septic tank, there are a few plants you may use safely, and then there are the ones you should avoid. Is it possible to grow plants over your septic drain field? If so, which plants are the most beneficial and which are the most detrimental? We will discuss landscaping and gardening ideas for septic tank owners in this post, which is written in English and Spanish.

Landscaping and Planting Ideas for your Septic Drain FieldSeptic Tank

Water is a precious resource in most rural and regional parts of British Columbia, and access to a public sewer system can be difficult to come by in many of these locations. As a result, many households and businesses in British Columbia require a septic system in order to function properly – both to conserve water and because there are no other waste disposal choices available when outside of the city sewage system. If your family or business relies on a septic system to manage waste, you will be acutely aware of the financial outlay you have invested in the system’s purchase, installation, and ongoing maintenance.

  • Because of this, it is critical to understand not just how your septic system works, but also how landscaping and planting can have an influence on the lifetime of your septic field.
  • What is the operation of a septic drain field?
  • The wastewater from your toilet, shower, kitchen sink, dishwasher, and washing machine runs to your septic system if your house or company does not have connection to a public sewer.
  • So, how exactly does a septic system function?
  • In your septic system, waste gradually separates, with liquids rising to the top and solid, inorganic waste (such as sand, synthetic fibers, and small pieces of plastic) settling to the bottom as sludge as time goes on.
  • Tank sludge must be pumped out at regular intervals, often every few years, to guarantee that the septic system continues to work effectively and lasts for an extended period of time.
  • The sewage system, as well as recycling This’soil absorption area’ is also referred to as a leach field or a septic drain field, depending on who you ask.

After a few preliminary phases, the ultimate treatment and distribution take place in this location.

(See Figure 1).

It is necessary for the effluent to drain at a sufficient rate in order for the organisms to operate efficiently.

Observations on Mound Systems In certain septic systems, such asAbove Ground Septic Systems or Sand Mound Septic Systems, the drain field is elevated above ground in an artificial mound, allowing for better drainage.

In regions where specific environmental factors (such as a high water table, shallow soil cover, and/or when the land drains too rapidly or too slowly) preclude the installation of a standard septic system, the system was created to address these issues.

Mound systems operate in much the same way as typical below-ground systems; however, the mound itself must be stabilized in order to prevent erosion and other disturbances that might cause damage to the drain field.

Septic Field Landscaping, is it necessary?

In a nutshell, sure. There are a variety of factors contributing to this. Perhaps most persuasive is the fact that planting on a septic drain field can assist to stabilize the region and lessen the likelihood of the soil cover eroding in the future. Erosion can cause damage to the drain field, which can be extremely expensive to repair because the drain field is often the most expensive component of a septic system. Besides that, plants have the ability to take surplus nutrients and moisture from the soil.

  1. The capillary action of the vegetation’s roots will also suck some of the wastewater out of the soil, which will aid in not only cleaning the water but also in removing some of the soil moisture from the environment.
  2. The planting of grass or low root plants is often required by code to aid in transpiration, erosion management (as previously indicated), and to provide insulative characteristics in cold areas, among other things.
  3. Landscape design over the septic tank will conceal the lids and access locations, while planting on the septic field will provide you with a lush grass and abundant plant life.
  4. Planting on your septic drain field with the appropriate grasses and plants not only improves the performance of the system, but it also completely conceals any underground infrastructure.
  5. Because the root systems of some plants can penetrate and cause damage to the pipes or other components inside the drain field, this is a major reason for this.

So, what should you consider when planting on a septic drain field?

In an ideal situation, you would choose plants that would fulfill your house or business landscaping needs while also maintaining the drain field as free of deep-rooted vegetative or weather risks as feasible. Finding out about a plant’s rooting tendencies and water requirements is the most straightforward approach to determine whether or not it is suitable for a drain field. Look for shallow-rootedherbaceous plants that are already established in your location or that have been acclimated to the average rainfall quantities in your region.

Choosing flora that is both shallow-rooted and drought-tolerant will help you to decrease your effort to a bare minimum totally. These kind of plants should require little to no watering, if any at all.

Some of the plants that are safe for your drain field are:

  • Holly shrubs, boxwood shrubs, azalea shrubs, Holly Hocks, wild violets, and spring bulbs are some of the options.

Some trees that are septic safe, including fruit trees, include:

  • Dogwood trees, Japanese maple trees, Eastern Redbud trees, and cherry trees are examples of such trees.

When planting fruit trees near a drain field, extreme caution should be exercised, especially if there is a surface breakout from the septic system. Pathogens such as Escherichia coli and Enterobacter spp., which can be transferred from the septic drain field to the trees, have been identified. It is recommended by North Dakota University that a root barrier be erected, since this will prevent roots from entering into the septic lines. A typical rule of thumb, while not always applicable, is to maintain a distance between the septic system and the tree that is proportional to the height of the tree.

Some of the worst plants and trees to cover a septic drain field or septic tank are:

  • Pussy Willow Shrubs, Japanese Willow Shrubs, Aspen Trees, Lombardy Poplar Trees, Birch Trees, Elm Trees, Maple Trees (other than Maple Trees), American Sweet Gum Trees, Ash Trees, Tulip Trees, Walnut Trees, Willow Trees, Cypress Trees, and Pine Trees are some of the plants that grow in this area.

It is also not suggested to grow shrubs with extensive root systems, such as Caryopteris (also known as Bluebeard or blue mist spirea). Planting vegetation with a deep root structure, water-loving roots that will develop aggressively deep and perhaps block or harm the pipes in the septic drain field is something you should avoid. As previously stated, septic systems – especially the drain field – may be quite expensive to repair. Furthermore, a faulty system might get extremely clogged and can have a negative influence on the environment.

(For example, avoid planting immediately before a major rainstorm.) You want the plants to establish themselves fast in order to reduce the likelihood of soil erosion.

Irritating the drain field can cause the soil to become saturated to an unacceptably high degree, preventing the effluent from evaporating and, as a result, increasing the likelihood of groundwater pollution.

Maintaining septic drain field vegetation

As much as you may want to plant over the drain field so that it integrates smoothly with your landscape and you forget that it exists, this is not the ideal option in most cases. Maintain visibility of your drain field, or make people aware of it through other methods, such as a plant barrier or fence. Holding big social events is discouraged; mowing the grass is OK; however, foot traffic should be kept to a minimum. If you are unclear of any potential conditions that might have a detrimental impact on your system, always consult with your Septic System Installer.

This is OK, as long as they are at least 50 feet away from your septic system and drain field, which is recommended.

Keep these trees at least 20 feet away from the septic tank and drain field, or as far away as the mature height of the tree allows you to go.

Can I plant a vegetable garden over the Septic System?

Because of the wastewater that seeps into the soil through the drain field pipes, the soil can become extremely wet and nutrient rich. The thought of using this by planting a fruit or vegetable garden over a drain field may seem like a good idea at first glance. Unfortunately, this is not encouraged – especially when it comes to creeping plants and root crops like turnips. Due to the fact that the vegetation will be in close contact with soil that is likely to be contaminated with disease-causing organisms such as viruses and bacteria, this is the case.

  1. However, leafy crops that grow near to the ground are also at danger of contamination because irrigation water that has spilled onto the foliage might contaminate the foliage.
  2. In general, the higher the crop is in height, the smaller the chance of contamination is to be found.
  3. It is quite likely that if you have a water softener in your home, your water softening system is adding salt to your septic system every time it regenerates, which is harmful to your health.
  4. In addition, depending on your septic system, the wastewater that ends up in your drain field may still include residue from home chemicals such as laundry detergent, which can be harmful.
  5. Furthermore, gardening tasks such as ploughing, deep digging, rototilling, and fence post placement must be included in.
  6. Raised garden beds, on the other hand, can have a substantial impact on the usual evaporation rate of wastewater from the soil.
  7. Herbaceous plants such as annuals, perennials (including bulbs), and decorative grasses will be the best choices for your septic drain field.
  8. In a previous section, we discussed the advantages of shallow-rooted herbaceous plants over alternative deep-rooted and woody-rooted options.
  • Covering the drain field with more dirt unless the amount is insignificant or the material is being used to repair an area that has been eroded or dragged up by the removal of another plant should be avoided.
  • Tilling the soil– If at all possible, avoid doing this. Please keep in mind that the pipe for your septic system drain field might be as near as 12 inches from the soil surface, and in some cases much closer.
  • Gloves– When dealing with the soil from your drain field, it is essential that you wear gloves. A virus might be present in the water leaking from your septic system into the drain field, and if it came into touch with your skin, eyes, or mouth it could cause you to get extremely sick.
  • Use of groundcovers– If you are selecting a groundcover for your drain field, such as a native grass or creeper, avoid using species that are known to form a thick, dense canopy over the drain field. In order for your septic system to work efficiently, the effluent in the drain field must be allowed to evaporate, which cannot occur if the ground cover is too thick.
  • Native species– Select plants that are native to your area and have a high level of adaptability. It will be less necessary for you to fertilize or water the drain field area as a result.
  • Make sure that there is no foot traffic on the septic drain field in order to limit the likelihood of damage occurring. Choose low-maintenance plants that don’t require a lot of attention or mowing

The following are some more suggestions for plants that do well in drain fields in British Columbia. This list is not exhaustive, so make sure to conduct more research to confirm that the plants you pick will survive in the circumstances that are typical of your region before purchasing them. Fescue, lawn, and ornamental grasses are examples of grasses. Meadow mixtures with wildflowers Groundcovers that are tolerant of the sun Kinnickinick heathers (Calluna) are a kind of heather (Arctostaphylos) Soapwort is a kind of plant that is used to make soap (Saponaria) Groundcovers for Providing Shade Bunchberry is a kind of berry (Cornus) Ferns that are indigenous to the area Mosses that are indigenous to the area Sweet Woodruff is a flowering plant that is native to the United States (Galium) Ginder in the wild (Asarum) Wintergreen (Gaultheria) is a plant that grows in the winter.

What plants can I grow in the septic field?

In the event that you have a green thumb, you may be wondering if you might plant a garden around your septic tank system. They present a difficult challenge since not all crops are appropriate for growing on drain fields. You must also exercise caution since excessive tilling and deep-rooted plants have the potential to cause the system to collapse. Some plants thrive in this environment more than others, and some water-loving plants, trees, and bushes may quickly outgrow their surroundings, encroaching on pipes and causing the septic system to fail if proper precautions are not followed.

Plants with shallow roots, such as grass, are the most common choice, but groundcovers and climbers can also be successfully planted.

Additionally, avoid installing raised garden beds over the absorption trench because this can impede the evaporation process and reduce the effectiveness of your septic system’s performance.

Overview of Septic Systems

It is usual to find septic systems in rural locations when the municipal sewage system is not readily available. Septic systems are made up of two parts: an aseptic tank and a leach area. The wastewater runs from the house to the septic tank, where the organic matter is decomposed and the water is recycled. Sludge, scum, and effluent are segregated into three layers: sludge, scum, and effluent. It is necessary to discharge the effluent (liquid waste) onto a leach field, where the soil absorbs the hazardous nutrients and cleanses the water before it reaches the groundwater table.

What plants can be grown over a leach field or absorption trench system?

Because a septic tank is often constructed at a depth of one meter underground, you don’t want the roots of your plants to go too deeply into the soil. Those with shallow roots that will not reach deep enough to impact the pipes or the septic tank are the greatest alternatives. Flowers, hedges, and grasses with shallow roots are the finest selections. These aid in the efficient operation of absorption trenches and the purification of effluent prior to its release into the environment, respectively.

Plants with shallow roots, climbers, and shrubs can be planted in the surrounding regions, but they cannot be grown immediately over an absorption trench or in the trench itself.

Fruits and vegetables should not be planted over the absorption field since consuming them may expose you to bacterial contamination, which is dangerous.

Tips for choosing the right plants for around your home wastewater treatment system

  • When it comes to septic systems, shallow-rooted plants and grass are your best allies. Plants that survive with minimal water or that are drought-tolerant are the most desirable
  • Choosing plants that can survive in a saline climate is important.

Factors that influence the vegetation around your septic system

  • Soil quality, nutrient levels, drainage, pH level, effluent quality, climate conditions, soil sensitivity of plants are all factors to be considered.

Chemicals such as detergents, fabric softeners, and household effluents can raise the level of salt in the soil surrounding an absorption region.

Check the pH level of the soil before planting; if the soil is alkaline, it may be preferable to pick plants that can withstand high salt levels.

Avoid planting trees near your septic system

When it comes to planting around a sewage system, trees are a no-no. When the strong roots reach deep enough in quest of moisture and nutrients, they can swiftly penetrate and obstruct the flow of water via the pipes. It is not advised to put trees or even plants on top of septic tanks or treatment systems. If you wish to grow trees or bushes, make sure they are planted far enough away from the septic system so that the roots do not reach the unit or drains of the system.

Plants safe for Septic Systems

This is not an exhaustive list, and you should consult your local nursery before making any final decisions about the plants you will be growing on or around your septic system.

Grass

  • Oyster plant, Royal mantle, Blue star creeper, Lily Turf, Native violet, and Perennial Aster are some of the plants that grow in this area.

Climbers

  • Bougainvillea, Snake Vine, Jasmine, Happy Wanderer, Glory Vine, Japanese Honeysuckle, and other flowers and plants

Shrubs

  • Jasmine, tea-tree, oleander, abelia and papyrus are some of the plants that grow in swamps.

Our expert septic management advice

  • Planting vegetables, fruits, bushes, and trees in close proximity to your septic system is not recommended. It is beneficial to have plants or grass growing over the leach field because it holds the soil in place and aids in the absorption of nutrients, which helps to avoid soil erosion and ensures effective operation of the septic system. No extra dirt should be placed over the drain field. Keep your hands protected anytime you are working in the garden over or around the drain field. In addition, growing plants increase oxygen exchange and soil moisture removal through transpiration, which are both important for plant growth. Immediately contact your localwastewaterseptic specialistif you notice water accumulating in the drain field or if water is backing up into your property. It is possible that your drain field has failed and that you will require an assessment and repairs. During the planting process, avoid excessive tilling of the soil, since this may cause damage to the pipes
