Before the arrival of herbicides and stump grinders, removing tree stumps was a laborious and time-intensive task. As a result of modern improvements in horticulture, ridding your yard of tree stumps is as simple as drilling holes and filling them with granules. Many stump-dissolving herbicides are composed of potassium nitrate, a slow-acting chemical that may take several weeks to dissolve stumps entirely.
Drill several 1-inch broad holes through the top of each tree stump by using a 1-inch spade bit and bit extension on a power drill. Make every hole about 12 inches deep and 3 inches from the edge of its stump.
Drill more holes that are around 12 inches deep across the surfaces of the stumps. Drill them every 3 to 4 inches apart from each stump shirt and at a 45-degree angle pointing toward the ground.
Pour potassium nitrate stump removal granules into a watering can that has a narrow spout, and pour the granules into all of the holes that you drilled. Fill the holes with water.
Wait four to six weeks for the potassium nitrate to dissolve the stumps. Keep children and pets away from the stumps throughout that moment.
Examine the stumps for sponginess. Chop spongy stumps with an axe to eliminate their parts. Fill cavities left from the stumps using soil or sod.
