The best way to remove Monkey Grass is to use a combination of hand-pulling and herbicide. For larger infestations, spraying a post-emergent herbicide, such as a glyphosate-based product, is actually the most effective means of eradicating the weed.
Make sure to read the product label and apply the herbicide according to manufacturer’s directions. After spraying, wait at least two weeks before attempting to remove the grass by hand. The manual removal of the grass involves grasping the weed by the base of the stem and pulling it up and out of the ground, root ball and all.
All removed weeds should be disposed of and not left in an area where re-sprouting is possible.
