How to Kill Ornamental Grass

Overview

Incorporating ornamental grasses is a good way to create texture and year-round interest in your lawn. But ornamental grasses must be chosen carefully. The wrong grass can overwhelm your yard. Some ornamental grasses spread easily and are considered invasive. Removing ornamental grasses can be difficult, due to the fact that many have razor sharp blades. Killing an ornamental grass must be done with care to prevent injury.

Step 1

Assess the size of your ornamental grass. Smaller ornamental grasses can be dug out of the lawn, but larger ones, such as mature pampas grass, have a massive root system that is not easily dug out.

Step 2

Pull on protective clothing, including gloves, long sleeves and long pants, safety goggles and close-toed shoes before killing ornamental grasses.

Step 3

Bind the grass into a sheaf using rope or bungee cords.

Step 4

Cut the grass to the ground using a chain saw.

Step 5

Dig smaller grass roots from the ground using a spading fork.

Step 6

Treat the cut stems of larger clumps of ornamental grass with a systemic herbicide containing glysophate.

Step 7

Cut back the grass clumps and reapply the spray whenever the grass shows signs of growing again.
