To remove a stump with chemicals, drill 1-inch holes 8 to 12 inches deep, fill them with potassium nitrate stump remover, add water and cover the stump. After 4 to 6 weeks the wood softens enough to break apart with an axe or mattock.
Before you start, compare this slow method with what stump grinding costs in your state.
Step 1: Cut the stump low
Cut the stump as close to the ground as possible to reduce the amount of wood to rot.
Step 2: Drill holes
Drill 1-inch holes 8 to 12 inches deep across the top, about 3 to 4 inches apart. Drill angled holes into the sides to meet them.
Step 3: Add stump remover and water
Fill each hole with potassium nitrate granules and soak with water. See our best stump removers.
Step 4: Wait and keep it moist
Cover the stump with a tarp and wait 4 to 6 weeks. Re-wet if it dries out.
Step 5: Break it up and fill the hole
Chop out the softened wood, then fill and level the hole as described in how to fill a stump hole.
