Given the chance, tree roots develop into septic system pipelines, slowing flow or plugging them. Copper sulfate kills tree roots in a leach area without digging, but some compound that isn’t taken up from the roots persists in the soil, where it can damage desirable plants. Digging up tree roots and pruning them eliminates the use of substances, but makes a tree susceptible to blowing over. Pruning is merely a temporary solution, and some older trees endure tension and die from the process. To keep roots eternally from the septic system, remove the tree and kill the stump so roots won’t ever return.
Saw through the tree back near the ground using the chainsaw. Do this when the tree is actively growing. Herbicide doesn’t operate on a tree that is dormant.
Drill five or six holes to the stump within 15 minutes of cutting down the tree. Pour glyphosate into each hole. Take care not to spill any on nearby plants you do not wish to kill, or even on the ground.
Cut up the tree and remove it in the region.
Determine whether any of the pipelines in the leach area are plugged by scraping away the soil over the manhole cover the septic tank using a shovel. Remove the manhole cover and check the liquid level inside the tank. It should be no higher than one foot from the top of the tank. A level less than 1 foot from the top of the tank can indicate a plugged line.
Dig up the pipeline nearest the tree roots that have invaded the leach field. Take care not to damage the pipe. Inspect it for roots growing into the pipe. If roots are growing to the pipe, dig up the conclusion of the pipe from the septic tank. These pipes are usually open-ended. Insert the sewer auger to the end of the pipe and cut out the roots. Replace the soil and pipe around the pipe as you discovered them.
Wake up and pull out tree roots that are at surface level of the leach field as soon as they’ve begun to decay. Roots die within a couple of hours or therapy, but it requires several months for them to decay. After roots deterioration, they’re easier to eliminate from the soil. Be careful not to dig to pipes in the leach field.
