How to Remove a Stump Using Saltpeter

After cutting down a tree, you will have a stump remaining. If you don't want to rent a stump grinder to grind the stump, you can use saltpeter, a form of fertilizer, to kill the stump. Using saltpeter on the tree stump will help speed up the decaying process, which can still take a couple of years. However, using saltpeter is an inexpensive way to remove a tree stump.

Things You'll Need

• Chain saw
• Safety goggles
• Drill
• 1-1/2-inch drill bit

Instructions

1. Cut the stump as low to the ground as possible with a chain saw without creating a safety hazard. Wear safety goggles to prevent injury to your eyes.

2. Drill six to seven holes in the top of the tree stump. Using a 1-1/2-inch drill bit at least 8 inches long, drill the holes at a slight angle about 8 inches deep.

3. Fill the holes with saltpeter.

4. Pour boiling water into the holes over the saltpeter. Do not overfill the holes. The water will cause the saltpeter to flow into the tree trunk. Once the water is gone, add more water. Continue adding boiling water until you have flushed away all the saltpeter.
