To kill a tree stump effectively, there are several methods you can use depending on how quickly you want results and the resources available:
Common Methods to Kill a Tree Stump
1. Epsom Salt Method (Safe and Environmentally Friendly)
- Drill multiple deep holes (about 10 inches) into the stump using a 1/2-inch drill bit.
- Fill the holes with 100% Epsom salt (magnesium sulfate).
- Water the stump to dissolve the salt without washing it out of the holes.
- Cover the stump tightly with a dark, waterproof tarp and secure it with rope or rocks.
- Leave it covered for 2-3 months until the stump is dead and soft enough to crumble
2. Herbicide Method (Fastest Chemical Way)
- Drill fresh holes or wounds into the stump to improve absorption.
- Use a systemic herbicide like Triclopyr, applying it with a foam paintbrush on the cut surfaces.
- The herbicide will be absorbed and kill the stump and roots within days.
- Use protective gear and dispose of materials safely
3. Controlled Burn Method
- Only use in safe, legal areas with no nearby flammable materials.
- Drill holes and soak the stump with kerosene.
- Ignite carefully and monitor the burn until the stump is destroyed.
- This method is fast but requires caution and permits
4. Grinding Method (Physical Removal)
- Rent a stump grinder.
- Cut the stump down to about 14 inches if necessary.
- Grind the stump and roots below ground level.
- Remove wood chips and fill the hole with soil or mulch.
- This kills and removes the stump quickly but requires equipment and effort
5. Rock Salt Method (Alternative to Epsom Salt)
- Drill holes and fill them with rock salt.
- Cover with soil and mulch, watering regularly to dissolve the salt.
- This dehydrates and kills the stump over several months
Methods to Avoid
- Do not use bleach or motor oil/fuel to kill stumps as they contaminate soil and groundwater and are ineffective
Summary
- For a safe, low-cost approach, use Epsom salt with drilling and tarp covering, but expect to wait several months.
- For quicker chemical action, use a systemic herbicide applied to fresh wounds.
- For immediate removal, grinding is the fastest but requires equipment.
- Controlled burning is fast but risky and regulated.
Choose the method that best fits your timeline, safety considerations, and environmental concerns.
