Use a weed wacker/string trimmer.

Do you just trim it where it lays, rather than trying to hold it up and "haircut" on clump at a time?

Lirope puts out only one flush of leaves a year. Run over it with a lawn mower before new growth sprouts in the spring.

The deer pruned mine! That's the only useful thing that they've ever done for me. But, I was prepared to use the lawn mower.

The lawn mower does a super job!

At this point in the spring lawnmowing may not work. If the new growth is above the mower blade you will chop the ends off, and it won't look right with square ends.
