Destroy Tree Roots to Guard Against Plumbing, Foundation, and Paving Damage

In the pursuit of maintaining a well-manicured garden, the need to remove unwanted tree roots may arise. However, it's essential to approach this task with care, considering the potential impact on the ecosystem and surrounding plants.

One method that has been suggested is using rock salt or Epsom salt to kill tree roots. While this approach can be effective, it's important to note that results may take several months to appear, and the salt can remain in the soil, potentially causing harm to the ecosystem.

Bleach, on the other hand, might not penetrate deep enough to kill the roots, instead causing surface damage. Pouring large amounts of bleach on a tree root is not recommended due to potential harm to nearby plants and the surrounding soil.

The Royal Horticultural Society (RHS) does not support the use of weed and stump killers due to potential damage to wildlife and other plants.

Herbicides such as triclopyr are effective, particularly on woody plants. These can be applied by drilling holes in the stump and large exposed roots.

Glyphosate herbicide, when mixed with water to create a 50/50 solution, can also be used to kill tree roots. This solution should be saturated around the outer ring of the tree stump.

Jane Dobbs, a horticultural expert, recommends using a glyphosate-based herbicide directly on the stump. She advises drilling several holes in the stump and large exposed roots, filling the holes with the herbicide or a salt solution, and covering the stump with a plastic bag to keep the solution in place.

However, it's crucial to exercise caution when using salt, as advised by Graham Smith MCIhort, who recommended certain chemicals for tree root removal back in 1982. He warns that salt can remain in the soil and potentially harm the ecosystem.

Before embarking on any tree root removal, it's essential to consider any local regulations. There may be restrictions around removing trees, roots, and stumps, so it's advisable to consult our guide to cutting down trees: the rules and regulations.

In conclusion, while there are several methods available for tree root removal, it's essential to choose one that minimises harm to the environment and other plants. Always consider the potential impact of your actions and follow any local regulations to ensure a safe and successful outcome.
