Liriope (also called lilyturf) is a tough, low-maintenance ground cover. It spreads quickly and can be left to its own devices once established. This perennial evergreen grass looks great grouped as a mass planting or edging. Liriope grows in USDA hardiness zones 6-11.
Remove grass from the area you're chosen to plant your liriope. Digging up as many roots and runners now will save you difficult weeding later. Crabgrass in particular can infiltrate liriope's thick clumps.
Choose a site that is either shady or sunny. According to the University of Florida Extension Service, liriope can tolerate no more than four to six hours of full sun in USDA zones 9-11. Liriope prefers a fertile and slightly acidic soil (ph 6.0 to 7.0), but it's really not very fussy and can thrive even in clay soil.
Dig a hole slightly larger than your plant's root system. Place the liriope in the hole, backfill with dirt and tamp down firmly to remove air pockets. Water thoroughly.
Mulch your liriope with pine needles or hardwood mulch. Water each week during the plants' first growing season. After that, you need water only in extreme drought conditions. Liriope does not like "wet feet."
Separate and divide liriope every 3-4 years. This will give your older plants breathing room and also give you new plants for your garden.
