Cutting down an oak tree is only half the battle when trying to kill it. New sprouts are generated naturally as a defense mechanism against the climatic elements and animals such as deer. Sprouting also helps to ensure continuation of the species through reproduction. To counter the growth of oak sprouts, it is necessary to kill the roots of the tree. For those choosing not to use chemicals such as herbicides, a more natural solution is available.
Cut the standing oak tree down with a hand saw or chainsaw depending on the size of the tree trunk. Cut the tree so the remaining stump is as close to ground level as possible.
Drill three to five holes into the stump and more along the roots where they have surfaced above ground. Space the holes 4 or 5 inches apart, and use the largest drill bit that the drill will handle. Drill at least 6 to 8 inches into the oak when possible.
Pack the holes with rock salt. Cover the stump and roots with 2 to 3 inches of soil. Use a shovel to spread the dirt. Water the soil to moisten thoroughly.
Add a layer of mulch such as miniature pine bark nuggets over the soil to help hold moisture in place around the stump and rock salt. The moisture will help with the decaying process.
Periodically rake back the mulch and soil. Add more rock salt as needed, and cover the stump again with soil and mulch. Continue until you see no sign of new growth from the roots or stump.
Things You Will Need
- Hand saw or chainsaw
- Safety glasses
- Drill with large bit
- Rock salt
- Top soil
- Have the tree removed by a professional if the height of the tree could pose potential problems when it falls in regards to utility lines, nearby trees or structures. Also consult a professional even if the tree is not that large, but you are not comfortable with any part of the cutting and felling process.
- Wear safety glasses for protection when cutting the tree and drilling holes.
