How Far Can You Plant A Tree From A Septic Tank? (Correct answer)

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.

  • As we mentioned in our previous blog, any trees or shrubs that you plant should be planted as far from the your septic system as they are tall. So a tree that reaches 30 feet in maturity will need to be planted at least 30 feet away from your septic system. Here at Septic Remedies, our goal is to be your one-stop-shop for septic tank care.

Can tree roots damage a septic tank?

Trees can cause significant damage to a septic system. Over time, tree roots can wreak havoc on the pipes and drain lines that lead out to the sewer or to your privately installed septic system. As a result, the roots can grow into the walls of the pipes and block the ability to drain water and waste.

Plants Safe to Grow Over Septic Tanks and Drain Fields

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

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 a tree on a septic field?

Placing trees or shrubs over or near the leach field is risky. Woody plants have deeper roots that may clog drain pipes in relatively short order. Water-loving species are especially chancy and should be avoided, such as willow, poplar, elm, red and silver maple, birch and beech.

How far should garden be from septic tank?

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 I plant a garden on my septic field?

Gardening over septic tanks is not only permissible but also beneficial in some instances. Planting ornamental plants on septic drain fields provide an oxygen exchange and help with evaporation in the drain field area. Plants also help control erosion.

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.

How close to a drain field can you plant trees?

Large trees are more likely to have extended root systems that can damage your leach field. Avoid planting beech, elm, birch, maple, willow or poplar trees close to your leach field. Never plant any tree closer than 10 feet to the edge of your leach field.

Can I plant a palm tree near my septic tank?

Only a few trees are considered safe for septic systems, and they are deep-rooted trees like cherry, crabapple, dogwood, oak, olive, palm trees and pine trees.

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 I plant a tree over a sewer line?

Select a Safe Planting Distance Keep all trees and shrubs at least 10 feet away from your sewer lateral. This goes for even the smallest, slowest growing species. Trees with spreading roots and species that require large amounts of water should be planted at least 20 feet from any underground pipe or utility line.

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. The following are some more plants and shrubs to consider planting near a sewage treatment 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.

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?

Keep in mind that you should avoid planting any plants near your septic system if you intend to eat the produce. Although you may see improved growth, none of the fruits or vegetables produced will be safe to consume.

  • 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.

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

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.

  1. Any huge, mature trees that may be growing in close proximity to your septic system continue to pose a threat.
  2. 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

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.

  • The introduction of more wastewater from the residence serves as a stimulus for their expulsion.
  • 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.
  • Drain field cloth can be used to protect dirt from getting into the holes.
  • “Percolation” is the term used to describe how wastewater moves through the earth.
  • The evaporation of excess moisture from the soil will take care of any excess moisture unless you (inadvertently) do something to hinder it.

A septic service must be hired at some time (usually after three years) to pump away the sludge and scum that has accumulated in the septic tank. The Spruce / written by K. Dave

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

Trees With Roots That Will Infiltrate Your Septic Tank

A septic system is made up of three parts: a main exit, a holding tank, and a drainage area, often known as a leach bed or leach field. The tank takes sewage from the building’s plumbing system, where it accumulates over a period of time until it is full enough to be discharged through an outlet onto the drainage field below. While the tank itself is typically resilient to tree root damage, the roots of some kinds of trees can represent a major danger to the proper functioning of the leach field, particularly in areas where the tank is located.

Tree Blacklist

However, while contractors and arborists generally feel that it is unsafe to plant any tree too close to a septic system, several species have been identified as being particularly undesirable. Among the most hazardous trees to septic tanks and sewer systems are elms (Ulmus sp.), gum trees (Eucalyptus sp.), cypress trees (Cupressus), maple trees, particularly silver maple (Acer saccharinium), birches (Betula sp.), walnut trees (Juglans), poplars (Populus sp.), and willows (Salix sp. Apart from seeking for the nearest and most abundant supply of water, the roots of these trees are also drawn to the vast stores of nutrients present in the soil around a septic system, as well as the oxygen found in the drainage lines.

Planting species such as weeping willows, Monterey pines, and walnut trees at least 100 feet away from the system may prevent them from becoming a problem.

Tree Root Facts

The root system of any tree is responsible for the majority of the tree’s water and nutrient absorption from the soil. Not all tree roots develop in the same manner, and the manner in which they do so is influenced by a variety of variables, including the kind of tree, the environment in which it grows, the quantity of yearly rainfall received, and the availability of water.

In order to find the most plentiful supply of water, tree roots naturally seek for the nearest and most abundant source of water. As a result, trees planted too close to a sewage system will have their roots grow in the direction of the damp soil surrounding it.

Septic System Facts

Modern septic systems are likely to have little more than 2 feet of soil cover, which makes trees with extremely deep taproot systems, such as oaks (Quercus sp. ), less of a hazard because their main roots naturally travel in a fairly vertical direction straight down into the soil. One element that leads to the invasion of tree roots into drainage systems is the presence of numerous holes in the pipes used to build leach fields, which allow any form of root to gain access with relative ease. It doesn’t take long for the strain from spreading roots to build up to the point when the pipes shatter and split open, which is usually constructed of PVC plastic.

Finally, as the obstruction increases, sewage begins to back up into the tank, and eventually the tank itself ceases to drain at all.

Safe Tree List

Generally speaking, the larger the tree, the more complicated its root system will be, and the reverse is true as well. Certain smaller types of trees, such as the Japanese maple (Acer palmatum) and the Amur maple (Acer ginnala), may not represent a significant hazard to a septic system. These are two of numerous trees that grow to no more than 25 feet in height, and they include the Japanese maple and the Amur maple. The University of Tennessee Extension also offers flowering dogwood (Cornus florida) as an excellent alternative, as well as smoke tree (Cotinus spp.) and Eastern redbud (Cercis canadensis), which are both low-growing species with limited root systems, according to the university.

It is normal for the roots of any type of plant to seek out and take advantage of the rich environment provided by the system when certain unanticipated situations exist.

What Trees Can be Safely Planted Near a Septic Tank?

Your septic tank is connected to your home by heavy pipes that run over and through your property. Because of the requirement of these pipelines, you may be wondering what you may safely grow in the vicinity of this location. It’s unfortunate, but there are some tree types that can cause major harm to a drain field or a septic tank, so you must exercise caution while working around them. However, if you follow the advice and information provided here, you may be certain that you have identified a few viable possibilities.

What to Plant Near or Over Your Septic Tank?

Please disregard any of the information you have received to this far. By selecting the appropriate species of tree or plant, you may actually aid in the efficient operation of your septic system as well as reducing the risk of erosion occurring on your property. It is likely that the plants that would thrive in this environment will have softer, greener stems and will have been adapted to the quantity of rain that is normally seen in your location.

Trees, believe it or not, may also be useful in some situations. Pick plants with shallow roots, and avoid placing them too near to the tank’s perimeter.

Fruit Trees, Japanese Maples and Oak Trees

While it is feasible to grow the three trees mentioned above near your sewage tank, doing so can be difficult. Because tree roots are naturally drawn to water sources, it makes sense that they would do so. It follows as a result that if you choose to plant your trees or shrubs in close proximity to your septic system, it is quite possible that they will make their way into the pipes and create difficulties. This will have a negative impact on the water flow in your home as well as the complete septic system.

Crabapples and white oaks are two examples of such trees.

Other varieties of fruit trees are also unlikely to be a good match for this particular variety.

Consider the implications of this.

Safe Trees for Septic Tank Areas

A list of trees that can be planted in and around the septic tank area can be found further down this page. Although it is recommended that you keep them as far away from your system as possible, it is still a good idea. Some plants to consider for these kind of environments are as follows:

  • The boxwood shrub, Hemlock, White oak, White pine, Pygmy date palm, American holly, Ornamental cherry, Lady palm, and Dogwood are some of the plants that grow in the United States.

Getting in touch with professionals is the best course of action if you have any more inquiries concerning trees or your sewer system. They may assist you in determining which trees are suitable for specific locations and which trees should be avoided due to the possible damage they may bring after they have reached maturity. Also, bear in mind the material presented below, which gives a useful summary of this essential subject matter.

Q: How far away from my septic tank should trees be located?

I am having my septic tank moved to the side of my house where I have fruit trees and other plants, and I am quite excited about it. Can you tell me how far away these trees should be planted from my septic tank? A: There is a plethora of material available on the internet about the topic of the distance between trees and septic systems. I’ve seen distances as little as 20 feet (at the University of Minnesota) and as long as 100 feet (at the University of Minnesota) (North Carolina State University).

  • It is crucial to note that tree roots can develop two to three times the distance between the drip line and the trunk.
  • Let’s imagine one of the fruit tree limbs was ten feet in length, which is not out of the ordinary for fruit tree branches.
  • Those roots have the potential to interfere with the natural processes of the septic tank and cause significant harm.
  • If you need to relocate the fruit trees, do so and then replant them in a new location.
  • When you move them, try to get as much of the root ball as you possibly can.

It is not necessary to alter the new hole where the tree will be planted; instead, it is sufficient to keep the trees properly hydrated. It is advisable to plant them during the dormant season to ensure the health of the tree and the production of future fruit. 0

Planting Trees With Shallow Roots Over Septic Systems

Do you have a septic tank in your home? In a recent blog post (Common Problem With Tree Roots), we described how the possibility for tree roots to grow into underground pipes, septic systems, sewage lines, or water lines is a major source of concern for house and business owners. As a result, except avoiding growing trees near your septic tank, what are some additional alternatives? Planting plants or trees with shallow roots over or near a septic tank is one option to consider. This might be a fantastic approach to create the landscape design you wish in a safe and limited manner with less restrictions.

Perennials and grasses with shallow root systems are typically the best choice for septic-safe planting solutions.

  • Salvia perennialis, Montauk Daisy, Delphiniums, Coneflower, Red Hot Poker, and Bearded Iris are some of the flowers that grow in the garden.

When planning your landscaping around your septic tank, keep these shade-loving plants in mind:

  • The Lenten Rose, the Bleeding Heart, the Bunchberry, the Hosta, the Leopard Plant, and the Jacob’s Ladder are all beautiful flowers.

The following plants and trees have shallow roots and may be planted atop sewage tanks, despite the fact that it is a bit riskier than planting ground covering grasses or perennials: The Japanese Maple Tree is a beautiful tree.

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

Important to note is that while you may believe that growing vegetation you want to eat near or above your sewage system is a good idea (since it will grow quicker), it is not always safe to consume fruit or vegetables that have been grown over or near a septic system. There are also several trees you should avoid planting over or near your septic system (usually, trees should be placed at least 50 feet away from subsurface drainage/systems), including the following: The Elm Tree

  • Japanese Willow Shrubs, Aspen Trees, Birch Trees, Beech Trees, Elm Trees, most Maple Trees, Ash Trees, and American Sweetgum Trees are some of the trees that grow in the area.

A huge tree’s aggressive roots may wreak havoc on the structures around it, including your home’s foundation, your driveway, your decks, and any subsurface drains or pipes on your property. It is critical to consider the location of trees in respect to these crucial structures in order to avoid costly damages. In the event that you are acquiring a new house, it is critical to have trees surrounding the property assessed for a variety of reasons, including their placement in proximity to key systems such as your septic tank.

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.

  • 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?
  • I’m not sure where to begin with my gardening endeavors.
  • (Answer)Congratulations on your major relocation!
  • In general, your septic system may be thought of as a little wastewater treatment facility.
  • 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).
  • 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.
  • 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:

This paper covers recommended separation distances between leaching beds and other structures such as gardens, trees, pools, and so on.

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.

Worst Trees for Septic Systems

Trees are often considered to be an addition to the home landscaping, but some species can pose a threat to subterranean pipelines if they grow too close. When determining where to build your septic system, it is critical to consider whether plants in the surrounding area may pose a threat to your tank. The root system of any tree is responsible for the majority of the tree’s water and nutrient absorption from the soil. Not all tree roots develop in the same manner, and the manner in which they do so is influenced by a variety of variables, including the kind of tree, the environment in which it grows, the quantity of yearly rainfall received, and the availability of water.

As a result, trees planted too close to a sewage system will have their roots grow in the direction of the damp soil surrounding it.

In other words, not every tree is equally dangerous, but as a general guideline, you’ll want to keep trees as far away from your water and sewage systems as possible.

Planting most trees near your septic system should be avoided as a general rule of thumb since they are potentially hazardous. Having said that, some trees are more aggressive in their behavior than others.

These are the worst trees for your home’s septic system:

As soon as a tree root reaches the surface of your septic tank, it begins to collect nutrients from the water contained within the tank. It is as a result of this that the root will also absorb chemicals from the water. Apart from the possibility of thousands of dollars in repairs, the tree may also begin bearing fruit that is dangerous to consume as a result of the damage.


Willow trees grow to be quite large and spread out. As a result, they require a substantial root system. They are well-known for spreading their roots far and wide in quest of moisture. For many septic tanks, the soil is just two feet deep, which is nothing in comparison to the depth of the roots of a Willow. Its roots have the potential to readily penetrate and destroy your septic tank.


Beech trees are majestic beauties that are well-known for their durability and height, among other characteristics. They have robust, shallow roots that may pose difficulties with both structures and pipelines, despite how impressive they appear at first. When you cut down a beech tree, the roots will typically send up sucker shoots, which will eventually grow into new trees. It is this same tenacity that causes beech tree roots to be a source of concern when they are placed close to subterranean pipelines.


In addition to the fact that they would aggressively grab for water sources such as willows, maple trees also generate a substance known as maple syrup, which works against them. When the roots of a Maple tree intrude into your septic system, you are confronted with not only the damage to your tank, but also an inedible batch of Maple Syrup for the upcoming fall season.


Despite the fact that they have a shallow yet powerful root system, eucalyptus trees may reach distances of up to 100 feet. The root system of the trees is intended to keep them alive in adverse conditions—and it even resprouts from these invasive roots when the trees are cut down and replanted. It should come as no surprise that the roots might make their way into water pipelines and septic tanks.

Honey Locust

Honey locust trees rely on a strong root system to support a top structure that is similarly strong. Suckers from honey locust trees, like those from many other species with invasive roots, grow freely from their roots, sending up prospective new trees that must be dealt with. Those roots can potentially cause issues with subterranean pipelines if they grow too close together.

Mulberry trees grow quite quickly, both in terms of sprouting and in terms of reaching maturity. Their success will be dependent on their ability to maintain a robust root system that will travel wherever the promise of moisture takes them—including ancient subterranean pipelines with leaky seams.


Aspen prefers to grow in thickets, which may provide a pleasing grove-like appearance. The thickets form from the root system of a single tree, which means that a single aspen tree may grow into a grove of similar trees stretching 100 yards over the landscape.

Although that free-roaming root structure is ideal for vacant areas, its performance near subterranean pipes in residential landscaping is less than optimal.


Empress trees are extremely fast growers, taking on 5 feet or more of growth each year on average. The tropical appearance of the large leaves, as well as the bright purple summer blossoms, have made the tree popular with certain people. Others, on the other hand, believe it to be a weedy pest. It has a very active root system, as do many weedy pests, and its roots can cause problems for subterranean utilities and pipelines.


Elm trees are drought tolerant and can survive in arid circumstances. They will, however, readily expand their roots in the direction of leaking old pipes if left alone. They can deal with drought, although they would prefer to have their fair amount of precipitation. When it comes to leaking underground drain pipes, that intense desire may be a dangerous trap.

Consider Planting These Trees Instead

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. The ideal plants to use around your septic tank and drain field are perennials and grasses (including decorative grasses). Because of their thin root systems, they are less prone to infiltrate and destroy the subsurface infrastructure. Small, non-woody ground coverings are a wonderful choice for the same reason: they are low maintenance.

It is important to remember that eating food crops grown on the ground around a drain field is not recommended 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, Azalea shrubs, Boxwood shrubs, and Holly shrubs are examples of ornamental trees and plants.

How Far Away from the Drain Field Should an Oak Tree Be Planted?

Almost any septic contractor will tell you that clogged systems are responsible for thousands of dollars in replacement and repair costs for homes every year. The roots of trees are frequently responsible for a clog. This problem, on the other hand, may be avoided by planting particular types of trees at a safe distance from the drain field and the storage tank. Oak trees are generally considered acceptable to grow in such regions because their root systems are less invasive and less extensive than those of other species.

In spite of this, there is evidence to suggest that this notion is incorrect, since mature oak roots may grow out as far as 90 feet or more from their origins.

Consequently, the minimum recommended planting distance should be the same as the expected height of the tree at maturity.

Bur oak and northern red oak are two types of oak that are regarded to provide a minimal risk to septic tanks and other septic system components. If you have reason to believe that tree roots are creating a hazard to your drain field, contact Lee KirkSons Septic in Lakeland, Florida, for assistance.

Anyone who works in the septic industry will tell you that clogged systems are responsible for thousands of dollars in replacement and repair costs for homes every year. Most of the time, it is the roots of trees that cause the obstruction. Planting specific types of trees at a safe distance from the drain field and tank, on the other hand, can help to avoid this issue. Oak trees are generally considered acceptable to grow in these types of environments since their root systems are less invasive and less extensive than those of other tree species.

In spite of this, there is evidence to suggest that this hypothesis is incorrect, since mature oak roots may grow out as far as 90 feet or more from their origin point.

So the minimum recommended planting distance should be the same as the tree’s predicted maturity height.

Placement of Septic Tank and Drain Field

If you’re looking for a new Underground Sewage Treatment System in Minnesota, Septic Contractors like Custom Septic, Inc. (CSI) will thoroughly evaluate numerous distinct aspects before recommending the optimal location. During the course of the project, some trees may need to be removed. They take into account factors such as the type of soil, the location of an underground water supply, and the size of the Septic Tank and Drainfield that will be required for adequate wastewater treatment.

Risks of Trees Too Close to Private Sewer System

  • Cracked sewer pipes as a result of tree roots getting into the pipes
  • Pipes that have been broken by trees that have been upended by a storm
  • Septic pipes clogged as a result of tree root invasion
  • Interference with the proper operation of the drainage field
  • Fruit has been contaminated by a root system that has burrowed into a sewage

Worst Trees to Have Near Drain Field

Maples, weeping willows, and poplars are some of the worst trees to have near a septic drain field, and they should be avoided at all costs. There is a history of their causing sewage system damage if they are planted fewer than 100 feet away from all septic system components. The majority of tree species should be kept at least 30 feet away from the drain field. When you look at the predicted height of a mature tree once it has reached full maturity, you may get an idea of the root structure.

This is only a simple rule of thumb that applies to a wide variety of tree species.

Trees to Avoid Planting Close to Private Sewer System

  • Weeping Willows, Silver Maple Trees, Red Maple Trees, Ash Trees, Birch Trees, Walnut Trees, Cypress Trees, Elm Trees, Cottonwood Trees, and Poplar Trees are some of the trees that may be found in the woods.

Can I Plant Near My Septic?

The planting of trees or big bushes within 10m of your septic tank or drainage field is discouraged by the EPA. The roots will naturally go towards your septic tank and drainage field, which are both excellent sources of water for the plant. Because tree roots are so powerful, they have the potential to burst through the concrete of your tank or the pipes in your drain field, causing a costly problem for you. This does not imply that the region around your wastewater system must be a desolate wasteland; there are still some possibilities for adding vegetation to the area.

What to avoid

Planting anything that you intend to consume within 5 meters of your wastewater system is not a good idea. Because your system’s primary function is to clean wastewater, the soil surrounding your system includes bacteria that should not be ingested by humans.

Large trees

It is a basic rule of thumb that a tree’s root system extends as far as the tree’s height in all directions. If you plant a tree that has the potential to grow to 5m in height, you may anticipate its roots to extend out to a distance of 5m from the tree’s base. As the expansion of giant trees’ roots continues, the water in your system will become more accessible to the roots. These roots are extremely powerful and have the potential to do significant damage to your tank and pipes.

What to plant

Grass is the most environmentally friendly alternative for foliage surrounding your system. You are free to plant grass over your tank and drain field without fear of contamination. The roots are superficial and do not pose a danger to your system’s integrity.


Planting flowers over your septic drain field is safe since flowers have short root systems and will actually assist to minimize soil erosion by absorbing excess water.

  • Elephants Ear
  • Coral Bells or Heuchera
  • Purple Coneflower
  • Cherry Pie or Heliotrope
  • Indigo Spires or Salvia

Small, drought-resistant shrubs

Generally speaking, smaller shrubs that have become acclimated to thriving without an abundance of water will not have extensive root systems and are therefore safe to place around your system.

  • Willow Myrtle, Swallow Wattle, Papyrus shrubs, and Oleander shrubs are examples of such plants.

Trees and Your Septic System – Septic Maxx

In virtually all circumstances, the best advise is to avoid planting any trees in close proximity to your septic tank or drainfield. Sewage system difficulties can be caused by trees growing close to a septic system because the roots can infiltrate the system, break through the septic tank, and grow beneath the drainfield. In the worst-case situation, a tree that has broken through a septic tank might result in thousands of dollars in repair costs for the property owners. In addition, planting trees that grow fruit or are otherwise edible near a septic system is nearly always a bad idea since the tree’s roots may absorb part of the sewage that is being discharged.

However, there are certain trees that, in some rare instances, may be safe to plant near a septic system due to the species’ very shallow root structure.

Trees You Should Never Plant Near a Septic System

  • Elm trees, walnut trees, and any other tree that produces fruit are all good choices. Any vegetable or anything that is edible
  • Maples, cypresses, and gum trees are examples of such trees. Any tree species that has been shown to have a large root system

Trees That Are Somewhat Safe to Plant

  • Smoke tree, Eastern redbud, shrubs, and tiny trees with extremely little root systems are examples of such plants.

Smoke tree, Eastern redbud, shrubs, and tiny trees with extremely short root systems are examples of what you may expect to see.
