How to Kill Kikiyu Grass

Overview

Kikiyu grass, also called kikuyu grass, is native to Africa, adapts well to temperate climates such as those in coastal areas of the United States. The aggressive weed tends to spread throughout turf grass, orchards and ornamental areas. Killing the grass may be difficult, as it forms a thick mat along with 1-to 4-inch-deep underground stems. Diligence and repeated treatments should produce the results you're looking for.

Step 1

Pull out kikuyu grass plants by hand, if there are only a few in the lawn.

Step 2

Test and adjust a garden sprayer. Fill it halfway with water. Spray the water on the grass or driveway. Twist the nozzle to adjust the spray.

Step 3

Funnel a glyphosate herbicide into the garden sprayer's tank. Follow the label instructions for mixing details, which may include adding water.

Step 4

Saturate the kikiyu infestation. Press the garden sprayer's trigger and move the wand back and forth over the area until it is covered with the herbicide.

Step 5

Pull up the kikiyu grass as it re-emerges.

Step 6

Apply the herbicide to the area after pulling the grass. Expect to reapply the herbicide two to three times after the initial application to permanently kill the kikuyu grass.
