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.

Skill level:

Things you need

  • Electric drill
  • Drill bit, 3.7 cm (1 1/2 inch)
  • Rock salt
  • Duct tape

  1. 1

    Attach a 3.7 cm (1 1/2 inch) drill bit to an electric drill.

  2. 2

    Drill a series of holes into the top of the tree stump. Make each hole on a 30- to 45-degree angle and 25 cm (10 inches) deep. Space the holes 5 cm (2 inches) apart in a circle around the top of the stump.

  3. 3

    Repeat the drilling on the side of the stump. Make the holes the same depth and angle, and space them 5 cm (2 inches) apart in a ring around the stump.

  4. 4

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

  5. 5

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

  6. 6

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