Monkey Grass Prevention

Q: How do I keep monkey grass from emerging in several different places in my yard?

A: My recommendation will be tedious, and you will hate me before long, but the only way I see to get rid of individual patches is to treat each one individually. Get a foam paintbrush and some nonselective herbicide. I recommend glyphosate or herbicidal soap. Dab the herbicide on each clump. Glyphosate is systemic and will travel down the leaves to the roots. Herbicidal soap kills only the leaves. The foliage will turn yellow by fall, and most of the clumps will be dead by next spring.
