Effectively Eliminating Liriope (Monkey Grass) with Glyphosate

Effectively Eliminating Liriope (Monkey Grass) with Glyphosate

Liriope (monkey grass) is tough but can be eradicated with glyphosate (Roundup) using the right technique.

Procedure

1. Bruise the foliage (rake, trample, or cut) to create entry wounds.
2. Apply glyphosate to the damaged foliage.
3. Timing: Early fall is best; spring applications are ineffective.
4. Repeat as needed—several applications usually required.

Safety Around Trees

Glyphosate is absorbed through green tissue only and does not move in soil. Spraying under tree canopies is safe if you avoid contacting desirable foliage.

Persistence and proper timing are key to complete removal.
