How to Use Brush Killer

Overview

If you live next to the woods or out in the country, you might have encountered woody brush. Some varieties of brush can be difficult to control. You might have cut them back to the ground, only to see them re-sprout and possibly even grow taller than before in a single year. Herbicide is the most effective way to remove this brush, but you can't just apply herbicide for weeds. You need a stronger herbicide that contains Triclopyr. These herbicides will typically be labeled as a brush killer.

Step 1

Purchase a brush killer herbicide that is in concentrate form. Look for a bottle that hooks up to the end of the garden hose. The bottle will mix the appropriate amount of herbicide into the water spray.

Step 2

Spray all the foliage of the brush in an even sweeping motion. Coat all the leaves until they are shiny and wet-looking. The herbicide will be absorbed into the leaves and trans-located to the roots.

Step 3

Check on the brush and allow up to 6 weeks for total kill. Do not spray any more brush killer during this time.

Step 4

Apply another round of brush killer to the brush if they are still alive after 6 weeks.

Step 5

Cut down the brush using a pruning saw and discard it in your yard waste or burn it for easy disposal if burning is allowed in your municipality.

Tips and Warnings

  • Don't apply brush killer during windy conditions. The herbicide can come in contact with desirable plants. It is non-selective, which means it will kill any plants it comes in contact with.
