How to Kill Hawthorn Stumps

Hawthorn is considered an invasive plant in some regions, and eradicating it can be challenging. Killing the stump effectively is essential to prevent regrowth. Here's a widely recommended method:

1. Cut the Stump:

- Use a chainsaw, lopper, or pruning saw to cut the hawthorn tree trunk close to the ground level, leaving the stump about 6-12 inches tall. Make sure the cut is clean and even.

2. Apply Herbicide:

- Once the stump is cut, immediately apply a systemic herbicide to prevent new growth from emerging. Glyphosate is commonly used for this purpose. Mix the herbicide according to package instructions and use a paintbrush or sprayer to cover the entire cut surface of the stump.

3. Drill Holes:

- Drill holes in the stump using a drill bit that's slightly larger than the width of your herbicide applicator. Drill several holes around the circumference of the stump and at least 2-3 inches deep.

4. Re-apply Herbicide:

- Pour undiluted herbicide into the drilled holes. Be careful not to spill herbicide on surrounding soil. Allow the stump to absorb the herbicide.

5. Seal the Holes:

- After applying the herbicide, use a sealant, such as wax, putty, or spray foam, to plug the drilled holes. This prevents further herbicide from escaping and reduces evaporation.

6. Monitor and Repeat:

- Wait for several weeks and monitor the stump for signs of regrowth. Hawthorn is known for its persistent nature and may require multiple treatments. If new growth appears, re-treat the stump by applying more herbicide.

7. Check Soil Contact:

- Prevent soil from directly contacting the stump's cut surface by removing any soil that may have accumulated at the base. This helps isolate the herbicide and prevents it from dissipating into the ground.

Killing hawthorn stumps can be a time-consuming process, but by following these steps consistently, you can effectively prevent regrowth and eliminate this unwanted plant from your property. Proper disposal of the treated stumps may also be required based on local regulations, so make sure to check and comply with any relevant laws.
