Fastest Way to Remove Unwanted Pampas Grass

Overview

Mature pampas grass clumps are massive and difficult to dig out. The quicker method: cut down, then treat with herbicide.

Step 1: Cut Down

Reduce clump to 3 feet or less using pruning shears. Bundle handfuls and chop away until manageable.

Step 2: Apply Herbicide

Spray all exposed surfaces with a glyphosate-based herbicide per label directions. Grass dies within two weeks.

Step 3: Remove or Decompose

Dig out dead roots or leave in place to decompose naturally.
