Q: I’ve noticed that liriope has taken over almost half of my nice carpet of mondo grass. Any tips for getting rid of the liriope without harming the mondo grass?
A: These two plants happily coexist with each other in the shade. There’s no product that’s selective enough to take the monkey grass out of the mondo grass. The easiest thing to do is mix up a bit of glyphosate in a small bucket and dab it on each liriope plant with a foam paintbrush. It will take time but that’s the only thing I know to do.
