Mondo grass – Weed control
Q: I have a dry stream bed with stone and dwarf mondo grass that has some weeds in it. How do I control them?
A: Image Kills Nutgrass (Imazaquin) (click for sources) kills many broadleafed weeds plus fescue, ryegrass and crabgrass. Sethoxydim (Poast) (click for sources) kills bermudagrass. Both are labeled for use on mondo grass.
Always read and follow the label
