How to Kill Tree Stumps With Salt

Unwanted tree stumps are unsightly blemishes in your yard that can be obstacles to proper landscaping. Accidentally mowing over roots from a low tree stump can damage your lawn care equipment. Killing the tree stump makes it easier to remove completely at a later date. Overdosing the stump with salt will effectively kill the stump.

Step 1

Attach a 1 1/2 inch drill bit to an electric drill.

Step 2

Drill a series of holes into the top of the tree stump. Make each hole on a 30- to 45-degree angle and 10 inches deep. Space the holes 2 inches apart in a circle around the top of the stump.

Step 3

Repeat the drilling on the side of the stump. Make the holes the same depth and angle, and space them 2 inches apart in a ring around the stump.

Step 4

Pour rock salt into each hole until the hole is full.

Step 5

Cover each hole with duct tape so rainwater does not dissolve the salt.

Step 6

Check the holes in two weeks. If the salt level has lowered, refill the holes. Repeat this until the stump is dead.
