Can tree roots penetrate septic tanks?
They can block or even break drainage and distribution pipes, and they can sometimes even penetrate the tank. Aside from sewer blockages and backups, tree roots growing inside sewer pipes are one of the most expensive septic maintenance items.
How far should plants be from 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. Some trees need to be located even further from a septic tank.
How do you keep tree roots out of septic drain field?
There are special chemicals designed to kill tree roots in a septic tank system so they don't grow back. Copper sulfate septic treatments are the most common. This method is especially effective as it creates a poison barrier within the soil that kills the tree roots before they can grow into the pipe.
Can I plant a tree over a leach 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.

What can you grow near a septic tank?
The go-to plants for your septic drain field will be herbaceous plants like annuals, perennials (including bulbs) and ornamental grasses. The advantage of ornamental grasses is their fibrous root system, which will hold soil in place and offer ground cover all year round.
Can you plant trees around a septic system?
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.

Can you put plants in a septic field?
Planting on septic drain fields and around your septic system and leach field is not only permissible but advisable. Plants will prevent erosion and suck up some of the excess moisture from the drain field.
Is it safe to plant a garden over a septic field?
Septic system disposal fields are designed to treat, or renovate, this wastewater. 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.
How far should a septic system be from trees?
The barrier should be at least 3 feet from the drain system so that it doesn't interfere with operation of the system, and no closer than 5 feet to the trees. It should run the length of the drainfield to prevent roots from growing around it.
How far should a drain barrier be from a tree?
The barrier should be at least 3 feet from the drain system so that it doesn't interfere with operation of the system, and no closer than 5 feet to the trees. It should run the length of the drainfield to prevent roots from growing around it.
What plants are dangerous to septic systems?
Although they aren't trees, bamboo plants have highly invasive and aggressive rhizomes. Some trees, such as red, scarlet or white oak (Quercus rubra, coccinea, and alba), have deep taproots and pose a smaller danger to septic pipes. Other such relatively benign species include dogwood (Cornus sp.), crabapple (Malus sp.) and cherry (Prunus sp.).
What tree species are good for drainfields?
Once you've cleared the field, removing trees that pose a threat, framing the drainfield with benign tree species, such as cherry or crabapple, provides ornamentation, helps bind the soil and might increase the life of the field.
What would happen if trees were growing on top of drainfield?
Minimum Safe Distance. Even if trees growing on top of the drainfield didn't pose a root problem for the pipes, they would still have to go because they're a physical obstruction. Trees in the surrounding landscape are a different matter, however.
Do you have to cut trees in a septic system?
Roots are attracted to the nutrient-rich fluids in the pipes, and if they start growing inside the pipes, they can cause system failure. You don't have to cut every tree in the vicinity of your new drainfield, though. Some are less damaging than others, and ...
What plants can be planted near a septic system?

Azalea Shrubs. Keep in mind that you shouldn’t plant any vegetation that you plan on eating from near your septic system. You might get better growth, but it won’t be safe to eat any of the fruit or vegetables produced.
What trees can be planted near a septic system?
Tree roots are often found to be responsible for the blockage, a situation that can be prevented by planting certain types of trees a minimum safe distance from septic tanks and drainage fields. Oak trees are believed to be among the safest trees to plant in such areas, as their roots systems aren't as widespread and are less invasive than those of other species.
How far can a tap root travel?
This initial root, or tap root, can travel vertically into the soil to as much as 5 feet before the tree's first leaves start to develop. The seedling's energy then shifts to the parts of the plant above the ground, and the tap root starts sending out side, or lateral, roots that grow horizontally away from the plant.
How do oak trees grow?
Oak trees propagate by means of acorns that fall from the trees in early autumn in most areas. Under the right conditions, acorns become quickly established where they fall, sending down a root often within days of coming into contact with the soil. This initial root, or tap root, can travel vertically into the soil to as much as 5 feet before the tree's first leaves start to develop. The seedling's energy then shifts to the parts of the plant above the ground, and the tap root starts sending out side, or lateral, roots that grow horizontally away from the plant. Lateral roots continue to grow in this direction in search of water and nutrients and are naturally drawn to the type of very fertile nutrient-rich, soil normally found near septic tanks and leach fields. Even if an oak tree is thought to be located a safe distance away from a drainage field, there is no guarantee that its roots won't seek out its effluents, especially if it is growing in an area that sees little annual rainfall.
How can oak trees be threatened?
In addition, oak trees are easily threatened by any type of root disturbance that includes building too near or over them, moving the soil above or near them, or trying to trim any that are protruding through the soil's surface. Along with being a potential threat to sewage systems, an oak tree's vulnerability to any type of disturbance reinforces the need to plan where it will go well in advance of the actual planting, as it will be too late to make any changes once the tree is established other than to cut it down. In short, locate oak trees in areas where there is the least likelihood that they will become problematic.
How far can an oak tree fan out?
Yet, the evidence detailing oak tree root growth contradicts this theory, as the roots of a mature oak tree can fan out as much as 90 or more feet from its base.
Is it too late to cut down an oak tree?
Along with being a potential threat to sewage systems, an oak tree's vulnerability to any type of disturbance reinforces the need to plan where it will go well in advance of the actual planting, as it will be too late to make any changes once the tree is established other than to cut it down.
Is oak a septic system?
Oak trees, including bur oak (Quercus macrocarpa), white oak (Quercus alba), and northern red oak (Quercus rubra) are considered to be low threats to septic systems by some organizations, such as the Morton Arboretum in Lisle, Illinois. While other types of trees such as willows are natural water seekers and shouldn't be planted in the vicinity of a septic system at all, trees such as oaks may be considered threats due their increased drought tolerance. Planting oaks at least 50 feet away -- or more, if the tree is going to grow into a big one -- from the farthest point of a drain field provides a relatively wide buffer zone, especially in areas that experience adequate rainfall.
How far away should I plant dogwood trees from a septic tank?

What happens if you fall into a septic tank?
If someone falls into a septic tank, most often they die. Quickly.#N#I would not lease such a property before finding out just what is installed, and making sure that the property is safe. In my opinion both property owner and leasee (you) could face liability if someone is injured. It's one thing for an owner to tell you not to walk on the grass, and it's a different problem controlling where visitors to the property may walk. Meanwhile, if the question is one of safety, rope off the area and keep people away.#N#If the owner thinks that stepping on a (safe, secure, properly-installed) septic tank or walking over one is going to hurt the function of the septic system, she's mistaken.#N#If the owner thinks that the reason to keep off the grass is because the septic system is in failure - pushing sewage effluent to the ground surface, an unsanitary condition - then she's right: you do not want people visiting your cafe to be walking in sewage effluent.#N#If that's the problem I would not lease the property until the septic drainfield has been repaired or replaced.
How far from a septic system can you plant hydrangeas?

Can't see weeds in drain field?
With the apology that I can only answer conceptually because I can't see your weeds nor do I know the construction of your drain field , the worry would be plants who send roots down deep enough to invade the absorption bed trenches and piping.#N#I suspect that most surface weeds are not a problem and I would just mow them when I cut my grass. If you wanted to be scientific about it or do the sort of experiment that I might try, you could pull out or dig up a couple of the most ugly looking or larger weed plants or other plants over the drainfield and take a look at the depth of their roots.
