. Mark the garden’s borders with stakes. According to the University of California Small Farm Program, fruits and vegetables should be planted at least 10 feet from a septic system or leach field to avoid bacterial contamination.
Is it safe to grow vegetables near a septic tank?
Septic tank vegetable gardens are not recommended. Although a properly functioning septic system should not cause any problems, it is very hard to tell when the system is working 100 percent efficiently. Vegetable plant roots grow down in search of nutrients and water, and they can easily meet wastewater.
How close can you plant next to a septic field?
A good rule of thumb is to use the ultimate mature height of the selected tree as the minimum planting distance from the septic drainfield, then increase the distance. For example, if you are planting a crabapple, plant the tree at least 25 feet from the nearest drain line; 50 to 75 feet would be even better.
Is it safe to put a garden over a septic field?
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. Vegetable gardening over a leach field is not recommended.
Can you put raised garden beds over septic field?
Tip. A raised garden can interfere with the functioning of a septic or drain field. Installing a raised garden bed over the leach lines is not recommended.
Can you put a garden near a leach 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.
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.
Can you plant trees around a septic tank?
There is still a danger posed by any large, mature trees that may be growing anywhere near your septic system. The general rule is that such a tree needs to be at least as many feet away from your septic drain field as it is tall. So a specimen 50 feet tall at maturity should stand at least 50 feet away.
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 you build 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.
How Far Can I Plant My Vegetable Garden From My Septic Lines?
Make sure you have an accurate schematic of your home’s septic system before you start digging in your backyard for a vegetable garden. Septic field contamination or damage might happen from planting a vegetable garden on top of a septic field, which is a costly and vital aspect of your home’s infrastructure. When it comes to vegetable gardens and septic fields, there are no set distance requirements. However, keeping your vegetable garden 10 to 20 feet beyond the boundary of your sewage system’s drainage field is a good bet for clean vegetables and an efficient septic system.
Get the Dirt on Septic Systems
The majority of septic systems are comprised of an underground tank that collects solids and perforated drainage pipes – generally four – that are placed from six to eighteen inches deep in gravel-filled trenches to aid in the disbursement of wastewater into the soil. The trenches can be 18 to 36 inches wide, 8 to 10 feet apart, and up to 100 feet long. They can also be 18 to 36 inches deep. The quantity and duration of these depend on the number of individuals that live in your family. The depth of the water might vary depending on the geology and terrain of the area.
Waste Not, Want Not
Agricultural waste that seeps into the soil in your drainage field has the potential to be drawn up into the roots of vegetable crops. Among the contaminants are infections that are transmitted through humans, such as viruses and bacteria such as E. coli, which you may consume. When it comes to root crops and low-growing greens, transfer is particularly dangerous since dirt can get on the leaves and spray up after watering or raining.
Digging In
In order to place plants and add soil amendments into vegetable gardens, constant foot movement, digging, and rototilling are required, all of which might cause disturbance to the septic field and potentially damage the pipes. Some vegetable plants have roots that can reach into drainage trenches, particularly those that are less than 1 foot below the soil surface, and cause the pipes to become clogged and ineffective.
Reducing Danger
You can lessen the likelihood of contamination when you absolutely must plant a few vegetables and do not have access to any other open soil, as described below. Plant vegetables that bear their fruit above ground and have a lower risk of contamination from direct soil contact – plants such as pole beans (Phaseolus vulgaris), cucumbers (Cucumis sativus), peas (Pisum sativum), and tomatoes (Lycopersicum esculentum) that can be trained to a trellis or stake have a lower risk of contamination from soil contact.
A covering of mulch prevents damp soil from splashing up onto plants and causing them to wilt.
Wearing gloves in the garden and properly cleaning all veggies with a soft-bristle brush under running water are both recommended procedures for every vegetable gardener, regardless of experience level.
Bulletin #2442, Vegetable Gardens and Septic Fields Don’t Mix
You can limit the likelihood of contamination when you really must plant a few vegetables and do not have access to any other open soil. Plant vegetables that bear their fruit above ground and have a lower risk of contamination from direct soil contact – plants such as pole beans (Phaseolus vulgaris), cucumbers (Cucumis sativus), peas (Pisum sativum), and tomatoes (Lycopersicum esculentum) that can be trained to a trellis or stake have a lower risk of contamination. Avoid eating leafy greens that are near to the ground or root vegetables that are grown in the soil.
Other options include cultivating plants at the far-reaching end of the septic field, where they are farthest from the tank.
Planning Around Your Septic System
In addition to an underground tank, a septic system also includes a soil absorption field, which is sometimes known as a septic system disposal field and is also referred to as a “leach field.” Through filtration and the work of microorganisms in the soil, the wastewater treatment field cleans the wastewater, preventing polluting water from entering nearby bodies of water such as lakes, streams, and groundwater.
Because of the presence of a septic system on your property, you may need to adjust your land use to accommodate the system.
This is especially true in the case of vegetable gardens.
What if You Don’t Know Where Your Septic System Is?
The challenge of locating your system is not always straightforward. Even if you are able to locate your septic tank, the disposal field may be several hundred feet distant. Refer to your septic system design form for assistance in locating your system (known as the HHE-200 form). Whether you are unable to locate a copy, you should inquire with your local plumbing inspector to see if he or she has a copy on file. Maine Subsurface Wastewater Program may be reached through the Maine Subsurface Wastewater Team page on the Division of Environmental and Community Health (Maine.gov) website, or by phone at (207) 287-5689.
If no record of your system can be discovered, you can contact a Site Evaluator to assist you in locating it.
How Septic System Wastewater Can Contaminate Your Garden
Untreated wastewater, commonly known as sewage, can be a health issue since it contains pathogens. Septic system disposal fields are intended to treat or refurbish the wastewater produced by septic systems. Because plants can become polluted by wastewater that has not yet been refurbished by a septic system disposal field, it is imperative that you do not grow a vegetable garden on top of, or immediately close to, a septic system disposal field.
Plants growing on disposal fields have the ability to absorb pathogens from wastewater. If you eat veggies that have been exposed to germs from wastewater, you might become quite ill.
What You Should Know About Disposal — Field Design
Since 1974, the majority of septic system disposal fields have been designed to be built partially or entirely above the original ground surface. This is due to the fact that the majority of Maine’s soils are hardpan, bedrock, and/or have a shallow seasonal groundwater table. A sufficient elevation above any of these limiting constraints is required to allow wastewater to flow into and be rejuvenated by the soil underneath the disposal field’s bottom layer of soil. How a disposal field is built is explained in detail.
- The upper layer is made up of components such as plastic or concrete chambers, fabric-wrapped pipe, geo-textile sand filters, or stone.
- A layer of compressed hay or filter fabric is placed just above the stone or other disposal-field components to prevent fine soil particles from entering the crevices between the stones or in other devices in the disposal field.
- A layer of fill material is placed above the compressed hay or filter fabric, which is typically eight to twelve inches deep.
- This is done in order to allow for the open flow of air into the disposal field, which will allow bacteria to immediately attack and refurbish the wastewater as fast as possible.
- The reasons why septic system disposal fields are undesirable for gardening purposes
- The wastewater level in a new septic system disposal field is often fairly low, especially in the early stages of the system’s operation. Over time, however, as the disposal field grows, it is possible that effluent will accumulate in ponds. A partial obstruction of the soil pores by particles escaping from the septic tank as well as the live and dead bodies of microorganisms is the cause of this. The greater the thickness of this clogging layer, the higher the level of wastewater in the disposal field will grow. The amount of wastewater produced will also increase over time as the number of family members grows and matures, as well as as a result of high-volume events. Water (including wastewater) will wick up into soil as a result of capillary attraction, and eventually the levels of wastewater in a disposal field will be high enough for even shallowly rooted plants to come into touch with it
- Even shallowly rooted plants will come into contact with it. The capillary pull of the wastewater might lead it to wick up to a height of 18 inches in the disposal field if it rises high enough in the disposal field to come into touch with the fill material on top of it. This could happen depending on the texture of the fill material. Consequently, it is not recommended to plant a vegetable garden next to a landfill fill expansion, especially if it is located close to the landfill. However, even though there may be no wicking up to the top of the disposal field or fill extension material at first, it is possible that it will occur as the disposal field matures. Generally speaking, the soil over the top of a septic system disposal field is very permeable, particularly in the early stages of the system’s installation. As a result, in order for the plants to thrive in a garden that has been planted on top of a septic system disposal field, irrigation will be required. Addition of water to the top of a disposal field, particularly if the disposal field is only moderately functioning, has the potential to cause it to collapse. Turning the top of a disposal field might cause harm to the compacted hay or filter fabric on top of the field. if the compressed hay or filter fabric is damaged, it could allow soil particles to migrate down into the stone or other devices in the disposal field, reducing the wastewater holding capacity
- If the compressed hay or filter fabric is damaged, it could allow soil particles to migrate down into the stone or other devices in the disposal field
- In order to provide a safe growing environment for vegetable plants on top of a waste field, it is not recommended to place extra fill on top of the field. The addition of fill material has the potential to choke the disposal field by interfering with the free flow of air in the area. It is significantly more probable for an anaerobic (oxygen-free) disposal field to become clogged and fail than it is for a well-oxygenated disposal field. Additionally, adding more fill material to the disposal system may result in damage to the components of the disposal field. It is expected that any plants put on top of the disposal field would shoot roots down in search of water and nutrients, which will not be found in the gravelly sand fill material used for the disposal field. After everything is said and done, septic system disposal fields are unsuited for gardening because roots that come into touch with wastewater might absorb infections such as viruses, which can subsequently infect anybody who consumes the plants.
Better Choices for Covering Disposal Fields
Grass is the most appropriate plant to grow on top of septic system disposal fields and fill extensions since it is drought resistant. Flowers may also be effective, but only if you avoid rototilling the soil and excessively watering the plants, as described above. It is not recommended to grow woody-rooted plants on disposal fields or fill expansions because the roots of these plants may choke pipes and other equipment in the disposal field, causing them to fail. The use of bark mulch to cover the bare soil of your disposal field is a suitable choice if you do not want vegetation to grow over your disposal site.

Septic System Gardening Info: Planting Gardens On Septic Drain Fields
Susan Patterson, Master Gardener, contributed to this article. A common source of concern for many homeowners is the planting of gardens on septic drain fields. This is especially true when it comes to planting a vegetable garden over a septic tank area. Continue reading to find out more about septic system gardening and whether or not it is advised to grow over septic tanks.
Can a Garden be Planted Over a Septic Tank?
Gardens over septic tanks are not only permitted, but they may be helpful in some circumstances. Septic drain fields benefit from the addition of attractive plants because they promote oxygen exchange and aid in the removal of moisture from the drain field region. Plants also aid in the control of erosion. Often, it is advised that leach fields be covered with meadow grass or turf grass, such as perennial rye, to improve the overall appearance. Furthermore, ornamental grasses with shallow roots can have a very pleasing appearance.
In either case, planting on a sewage bed is permissible as long as the plants you choose are neither invasive or deeply established.
Best Plants for Septic Field Garden
A septic field garden should be planted with herbaceous, shallow-rooted plants such as the grasses indicated above, as well as other perennials and annuals that will not damage or clog the sewage lines. Planting trees and shrubs over a septic field is more challenging than planting shallow-rooted plants over a septic field. It is possible that tree or shrub roots may cause damage to pipelines at some point in time. Small boxwoods and hollybushes are preferable than woody shrubs or huge trees in this situation.
Vegetable Garden Over Septic Tank Areas
It is not suggested to grow vegetables in a septic tank. Although a fully functioning septic system should not create any difficulties, it can be difficult to determine whether or not the system is operating at peak performance. As vegetable plant roots grow downward in search of nutrients and water, they may come into contact with sewage or other liquid waste. People who consume the plants may become infected with pathogens such as viruses. Whenever feasible, it’s a good idea to reserve the space above and near the septic field for decorative plants and to locate your vegetable garden someplace else on the property.
Septic System Gardening Info
It is generally a good idea to obtain as much information as possible about your specific septic system before you begin planting. Consult with the house builder or the person who built the septic system to see which option would be the most appropriate for your unique scenario.

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. It is not suggested to grow vegetables over a leach field.
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.
- 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.
- Solid woody plants have deeper roots that have the potential to clog drain lines in a very short period of time.
- 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.
- The roots of a tree will normally reach at least as far from the trunk as the tree’s height from the ground.
- 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.
- Furthermore, residential effluent typically contains significant quantities of sodium, particularly if you use a water softener.
- It is not a good idea to plant vegetables over a leach field.
- 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.

Planting Vegetables Over a Septic Leach Field
It it OK for me to establish a vegetable garden on the drain field of my septic tank. – Eric et al. The drain field of a septic tank makes for an attractive location for a vegetable garden since it is vast, flat, and typically sunny. However, it is typically not suggested to grow vegetables in this location for a variety of reasons, including the following:
There is a risk of contamination:
- As septic tank effluent drains out into the lines, it is gently filtered through the soil, where helpful soil microorganisms digest dangerous bacteria and viruses, allowing the effluent to return to the tank. This indicates that there is some level of contamination around the lines, and the extent of the contamination is dependent on the kind of soil, the rate of absorption, and the overall quality of the system. Septic systems are intended to prevent disease-causing soil pollution, but there is no simple method to determine whether or not your system is working correctly. Consider all of the home chemicals that are flushed down your drains on a daily basis, in addition to bacteria. In general, plants benefit the environment by absorbing and digesting chemicals – some of which may wind up in your food. Root crops are more susceptible to contamination, and their roots can become entangled in drainage systems. Leaves and vegetables might be polluted by water that has splashed up from the soil surface. Higher-growing or fruiting plants (such as tomatoes and cucumbers) are less likely to be infected
- But, there is no way to know what kinds (or how much) bacteria are present on them. It is possible that you have a water-softener system that may release brine (salt) into the system, which will hurt salt-sensitive veggies such as peppers and beans
- Nevertheless, it is not recommended.
Also, the proper functioning of your septic system can be harmed by:
- The use of raised beds that hinder the evaporation of moisture
- Tilling, excavating, and foot traffic are all activities that might cause damage to septic lines. It is irrigation that causes the delicate process of filtration and evaporation to be disrupted.
Instead of vegetables, you should plant your septic drain field with decorative plants, grasses, or ground coverings that have shallow roots and are drought resistant. For further information and plant recommendations, please see:

Can You Plant A Garden Over A Septic Field?
The rear corner of my land is where I’m planning to develop my garden, but while I was talking about my plans with a buddy, he said that his home is equipped with a septic tank, which made gardening a bit more difficult. It’s not something I have to be concerned about, but it’s something I would be concerned about if I lived in a property that relied on a septic tank for waste disposal. I recall that my sister had a septic system installed on her property some years ago, and she also had a flower garden on her land.
- Despite the fact that you are cautious about what you are growing and are aware of the hazards associated with probable contamination and damage to the septic system, you should not plant a garden over a septic field.
- These are the start of two very distinct inquiries.
- Yes.
- No.
- Gardens flourish over septic fields for the same reason they flourish when manure is incorporated into the soil: there are an abundance of nutrients available for your plants to absorb and use.
- However, vegetable gardens and flower gardens are two whole different things.
- A little manure on my garden soil is fine with me, but having bacteria contaminates splashed all over my food is not something I am interested in.
For me, it’s a question of not knowing whether or not the septic system is properly functioning or whether or not I’ve caused harm to it, and I don’t want to take any chances with my health or with the septic system’s functionality.
If you’re dead set on starting a vegetable garden, but your only option is to dig up a septic field, you’ll want to think twice before proceeding.
If at all possible, avoid planting root vegetables immediately over drainage lines because if there is contamination, the root vegetables will absorb it and this will be detrimental to your health.
Planting tomato and cucumber vine crops in cages and trellises will keep the plants off the ground and prevent as much splashing from water impacting the soil as is feasible.
Raised garden beds should not be used because they make it harder for your septic system to drain correctly since they hold too much water in the soil.
Oh, and please, please, please do not place your garden next to a septic field.
In reality, growing over your septic field is not a significant concern for most garden plants (with the exception of root vegetables), but it might cause problems for your sewage system and lead to the contamination of your food supply.
Apart from this, you should also think about keeping some other objects away from your septic field.
Some of the drainage lines are rather close to the surface, and even tiny machines such as 4-wheelers, dirt bikes, and riding mowers might cause an issue and break the drainage lines as a result of the weight of the vehicle.
You should also avoid hardscaping or planting raised beds directly over the septic field.
RELATED QUESTIONS
After persuading you to keep your garden away from the septic field, you’re probably wondering how close you can get to the edge without falling off. Keeping your fruit and vegetable plants at least 10 feet away from the outer perimeter septic system or leach field is the safest chance for avoiding contamination and avoiding damage to the septic system itself, which can be quite costly.
Can I place a raised bed over a septic field?
Placing a raised garden bed on top of a septic field might be fatal. Don’t even think about it! However, while this may assist to protect your plants from a higher danger of pollution since it effectively shifts the plants and roots further away from the septic system, it will cause problems with the septic system itself. Septic systems and leach fields must be able to drain moisture from the system. Placing a raised garden bed on top of your septic system or leach field keeps rainwater from escaping and can cause harm to the system and surrounding area.
Everything from paths and pavers to firepits and raised garden beds should be avoided over your septic system since it will prevent rainwater from evaporating.
safe distance for garden from septic field
If anything in my initial response came off as condescending, please accept my apologies; nevertheless, please be assured that this was not my aim. Although human waste is used as fertilizer, it is most commonly found in Asian countries, as well as in the United States of America, where it is found in the form of processed sludge from sewage treatment plants (although the latter is still somewhat controversial, partly due to concerns about the very real health risks if it is not done correctly, and partly due to the “Ohhhh, gross!” factor).
According to the Institute of Natural Resources, the standard distance minimum for separation of any portion of a septic system from a private water well is 100 feet (may vary by locale; probably does).
I can’t imagine that a similar separation between the lines of a garden and the roots of plants would cause a problem (I have heard of instances where the separation was significantly less, with no apparent ill effects), but you might want to check with your local health department to see what they say.
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.
A smart choice for ground coverings is tiny, non-woody ground covers for the same reason. It goes without saying that there are several instances of such plants, so you will want to limit down your options. Consider the following growth conditions as a good place to start:
- 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. Dave’s / K. Dave
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.

The Basics of How Septic Systems Work
In general, avoid planting huge, fast-growing trees in your landscape. Aside from that, trees and shrubs with active root systems are among the greatest offenders, since they seek out and use water at an alarming rate. Their preference for the water supply they use means that the pipes in your septic tank’s drain field are completely fair game for them. Among the most well-known examples are weeping willow trees. Many trees and bushes should be avoided, however the following are only a few examples: No matter how careful you are with your landscaping, you should avoid planting any of the most troublesome plants immediately over your septic tank’s drain field.
Existing huge and mature trees that may be growing anywhere near your septic system continue to pose a threat.
To put it another way, a mature specimen that is 50 feet tall should be at least 50 feet away from you.
Otherwise, root barriers can be installed to prevent tree roots from infiltrating your septic drain field, although this is not always successful (similar to the bamboo barriers used incontrolling invasive bamboo). An example of this would be the Spruce K. Dave’s Contribution

Planting over a septic leach field (drain field) is possible, but it must be done with caution to avoid contamination. 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.
How close can you plant a garden to a septic field?
DO NOT grow vegetables in close proximity to your sewage tank. If you want to avoid bacterial contamination, you should grow your fruits and vegetables at least three meters away from the drainage field of your septic tank. Although this appears to be a straightforward concept, it is really crucial to bear in mind when you plan your planting!
What plants are safe to plant near septic systems?

6 Things to Know About Landscaping Around Your Septic Tank
You’re undoubtedly already aware that dumping some items into your sewage system, such as paint or grease, can cause harm to your septic tank. However, you may not be aware that certain gardening methods can actually cause harm to your septic system. In order to avoid unwittingly causing difficulties or damage to your septic tank, here are six things you should know regarding landscaping around your septic tank. 1. The location of the access point. It is OK to use landscaping to conceal the entry port to your septic tank; however, you must not totally conceal it.
- One option to conceal your access port without totally concealing it is to use a landscaping element such as a birdbath or any other fixed lawn decoration to mark out its position on the property.
- Characteristics of Vegetation that is Safe It is possible for some species of vegetation to grow above and around a septic tank without the risk of septic tank damage rising.
- You should also limit the vegetation that grows above your tank to plants that do not require a lot of water.
- In order to grow anything other than grass over your sewage tank, use perennials that are drought-resistant to the elements.
- Characteristics of Trees that Have the Potential to Be Destructive Large bushes or trees should not be planted anywhere near your septic tank under any circumstances.
- In the case of a 20-foot-tall tree, it is recommended that it be placed at least 20 feet away from the septic tank.
- Trees with actively growing roots can cause damage to septic tanks and pipelines, even if they are located a long distance away.
4.
Grazing animals consume the protective vegetation that covers your drain field, exposing the components of your septic system to the elements.
There are a lot of methods you may use to keep livestock from grazing on your septic tank.
You may also apply animal repellents around your drain field, which deter animals by emitting unpleasant sounds or odors that they find uncomfortable.
Preventing vehicular and pedestrian traffic.
Your landscaping should be planned and your yard should be put out in such a way that cars do not drive over the area where your septic tank is positioned.
Foot traffic, in addition to car traffic, can cause damage to a septic tank.
As an alternative, if possible, direct foot traffic away from the area.
The Positioning of Architectural Elements You could choose to include architectural elements into your landscaping, such as retaining walls, stone paths, or fire pits.
If you plan to incorporate architectural elements into your landscaping, be certain that these elements are located far away from your septic tank. Get in contact with Walters Environmental Services if you want to learn more about maintaining your septic tank in excellent working order.
West Coast Gardener: Gardening Around Your Septic System
NEWater SepticDrainage Ltd.’s John Langard contributed to this article. Incorporating gardens and establishing a landscape plan for newly constructed homes or older homes with onsite sewage systems (septic systems) may be both gratifying and demanding endeavors. There are several different types of septic systems, each with a distinctive appearance in your yard. These range from an in-ground gravity system with a single tank to a raised sand mound with a treatment plant and up to three tanks, among others.
The following are some general guidelines to consider while landscaping over a septic system drain field: Keep all irrigation lines at least 10 feet away from one other.
On or near your drain field and septic tank, keep plants and shrubs with aggressive root systems out of the way, such as cedar, willow, maple, bamboo and aspen.
Do not plant anything near your septic field that will interfere with water drainage.
However, a blend of wildflowers and other grasses may be used to produce a low-maintenance, meadow-like look that is low in care.
If you are going to plant flower gardens, annuals and perennials with shallow root systems are suitable selections for your planting needs.
A well built and operating drain field can help support the growth of vegetable gardens, albeit it is not suggested for use with an old-fashioned gravity system.
Planting root vegetables over your septic field is not recommended.
Now is an excellent time to think about any new landscape ideas you may have.
Any landscaping or garden features, as well as the construction of any retaining walls within 25 feet of your drain field, should be discussed with your maintenance provider or landscape designer before beginning work.
