Pruning liriope in early spring
Cold weather can leave liriope (commonly called monkey grass) in tatters. Flower bed edging and driveway borders can be come overgrown and unkempt if the liriope is not kept compact. If your monkey grass is bedraggled or uneven, a Marine “brush cut” might help it.
The best time to trim monkey grass is January – March. If you can adjust a lawn mower to its highest setting, it can be used to remove all of the old greenery from the last few years. New sprouts have not emerged yet and will not be harmed by the mower. If you wait much later, the trimming must be done with a hedge trimmer, after first checking to see how tall the new sprouts have grown. Make your cuts just above these sprouts.
