Cutting down trees irresponsibly is not recommended, but sometimes it becomes necessary to remove a tree for various reasons. While cutting the tree itself is easy, removing the roots is the most challenging part. Tree roots cannot be left to grow in unwanted directions, as they may clog sewage lines, crack pavements, or take up unnecessary space and create an unpleasant appearance. You can hire a professional to remove the roots, or you can do it yourself using the right tools.
How to Get Rid of Tree Roots
There are several methods to remove tree roots. Here are the most effective ones:
1. Manual Root Removal
Manual removal is done as follows:
- Dig around the tree roots until they are completely exposed.
- Pull out the loosened roots and cut any visible ones, taking care to avoid the main root ball.
- Use a shovel to lift the cut roots, continuing to cut and lift until you can remove the entire root ball.
- If manual removal becomes too difficult, you may use an electric saw or a stump grinder.
2. Removing Roots Using Chemicals
Chemical removal involves the following steps:
- Use a saw to make fresh cuts on the tree stump, then spray it with water—moisture helps distribute the herbicide into the roots.
- Mix a herbicide with water in a 50/50 ratio and spray it onto the stump, avoiding nearby plants.
- After two weeks, the tree roots will die completely.
3. Removing Roots Using Rock Salt
Rock salt can also be used:
- Drill several holes, 7–10 cm deep, into the stump and any exposed roots.
- Fill each hole with rock salt, then add enough water to dissolve it without spilling outside, as it may damage other plants.
- Repeat monthly. The salt will absorb moisture, preventing the roots from taking up water until they die.
4. Encouraging Natural Decomposition
Dead wood—including stumps and roots—will naturally decompose when exposed to moist soil. To speed up the process:
- Cover the roots with grass clippings or organic waste.
- Alternatively, dig around the roots and apply a pile of compost on top.
- Check the roots periodically for signs of decay.
5. Poisoning Tree Roots
Commercial root-killing products are available. You’ll need to make cuts in the stump and roots, then apply the product inside. These chemicals—often containing potassium nitrate—kill the roots and accelerate decomposition without damaging the surrounding garden.
How to Remove Tree Roots Without Harming the Tree
Sometimes you may need to remove harmful roots without damaging the entire tree. This can be done safely by following these steps:
- Identify the root you want to remove and measure the tree trunk’s diameter.
Multiply the diameter by three to determine the closest safe distance at which you can cut without harming the tree.
Avoid major structural roots and never remove more than 20% of the root system. - Dig at a safe distance from the trunk until the roots are exposed.
- After exposing the root, mark the section to be removed using paint.
- Use pruning shears or a mechanical saw to cut the marked section.
- Install a root barrier approximately 75 cm below soil level to prevent regrowth.
