A tree stump on your property can be both unsightly and dangerous. Without any intervention, a tree stump will eventually rot. This process may take many years to happen naturally. There are a few things you can do to speed up the process. Microorganisms are responsible for eating the rotting wood. By fertilizing the stump and keeping it moist and covered, you will give the microorganisms the best environment to do their work. Cedar, mulberry, Osage orange and locust trees take the longest to rot.
Place the chain saw on the side of the tree stump as close to the ground as possible. Cut across the tree stump, removing as much of the top of the stump as you can.
Drill holes into the stump using a drill with a 1-inch drill bit. Each hole should be at least 3 to 4 inches deep. Drill as many holes as the stump size allows. Each hole exposes a larger area of wood to the microorganisms that will eventually decompose the wood.
Apply the fertilizer over the stump at the manufacturer's recommended strength. Do not use fertilizer at a stronger than recommended strength. Excessive nitrogen levels can burn the beneficial microorganisms.
Cover the tree stump with a plastic tarp. Place one brick at each corner to keep the tarp in place.
Check under the tarp every few months. You will notice the stump decaying. After one year, sprinkle a thin layer of sugar over the stump to feed the microorganisms.
