Big Blue Lilyturf

Year-round

Liriope is an easy grassy edging plant that handles sun or shade, sandy soil, and dry spells once established.

• Grows in full sun to part shade and tolerates near-full shade with slower, floppier growth.
• Needs well-drained soil, which sandy Long Island yards already have.
• Water regularly the first year, then very little.
• Deer and rabbits generally leave it alone.

Liriope makes a neat, HOA-friendly edge along walks and beds.

Fall

Fall needs just a little tidying, and it is a good time to plant new clumps.

• Remove any leaves that look spotted or rotted.
• Plant or divide in early fall so roots settle before winter.
• Keep new plants watered until the ground freezes.
• Wait to cut back until late winter.

Winter

Winter leaves can look ragged on Long Island, and that is fine. Cut them back as spring nears.

• Shelter new plantings from cold wind if you can.
• Leave the leaves for now to protect the crown.
• Plan to cut tops back each February before new growth begins.
• No watering needed unless the ground is dry and unfrozen for long.

Spring

Early spring is the time to cut it back and give it a light feed.

• Cut the old leaves back before new growth starts, typically late winter to very early spring.
• Add a light slow-release or organic fertilizer in early spring.
• Watch for slugs and snails on new growth.
• Divide crowded clumps now if you want more plants.

A spring haircut keeps borders looking fresh from the street.

Summer

Summer is easy. Water new plants and let established ones ride out dry spells.

• Water new plantings regularly to keep soil moist in their first year.
• Established clumps are drought tolerant and need little extra water.
• Skip heavy fertilizer, since it is a light feeder.
• Check for slugs, snails, or crown rot in wet, shady spots.

Year-round

Big blue lilyturf is a tough grassy clump that holds a neat edge in Ozark yards with thin rocky soil and hot humid summers.

• Give it part shade to full sun. In Springfield area heat, afternoon shade keeps the leaves greener and less scorched.
• It handles the thin cherty soil over limestone as long as water drains. Work in a few inches of compost at planting to help young roots.
• Space plants 12 to 15 inches apart for a solid edge or groundcover under trees where turf gives up.
• Water weekly the first season. After it is established it takes dry spells well.
• This is the clumping kind of liriope, not the running kind, so it stays where you put it instead of creeping through the bed.
• Purple flower spikes come mid to late summer, then dark berries follow.

Its low, even mounds make a clean front-yard edge along walks and driveways, which reads as intentional to an HOA-conscious neighbor.

Fall

Fall is a good planting and dividing window, and the black berries show up after the flowers fade.

• Early fall planting works well here. Soil is still warm and the fall rains help roots settle.
• Dividing in fall is fine too if you missed spring. Give divisions six weeks before hard freezes.
• Leave the foliage standing going into winter. It is your evergreen cover and it protects the crown.
• Dark berries follow the flower spikes and hold on the plant.
• Keep fallen tree leaves from packing down on top of the clumps so the centers do not stay soggy.
• No fall fertilizer needed.

Skip a fall cutback here. Liriope looks tidier left standing through winter, and the real trim belongs in late winter.

Winter

In zone 6b to 7a the foliage usually persists but gets beat up by cold, and that is normal.

• Expect leaves to go tan, streaked, or flattened after hard freezes and ice. The crown is still alive underground.
• Do not pull or rake at damaged leaves. Wait and shear the whole clump in late winter.
• Leave a light mulch layer around the base for winter root protection in exposed street-edge beds.
• Avoid piling shoveled snow with road salt onto liriope along the driveway or sidewalk.
• Nothing to water in winter unless you get an unusually long dry warm spell on a new planting.
• Plan your late winter shear for late February or early March, before new blades appear.

If winter-burned foliage looks messy out front, that late winter shear is the fix, not a mid-winter cleanup.

Spring

Late winter into early spring is when you cut back the old tattered leaves, and it is the best window to plant or divide.

• Shear or mow the whole clump to about 3 inches before new growth pushes, usually late February into March in southwest Missouri.
• Set the mower on its highest setting for a big edging run. Hand shears work fine for a few plants.
• Do not cut after the new blades start showing or you will leave them with blunt clipped tips all year.
• Divide crowded clumps now. Dig, pull apart into fist-sized pieces with roots, replant at the same depth.
• Plant new divisions in spring so roots settle in before summer heat.
• A light feeding of general purpose fertilizer after cutback is plenty. It does not need much.

Do the cutback in one pass across the whole front-yard run so the edging looks uniform rather than half trimmed.

Summer

Summer is easy, mostly just water during long dry stretches and enjoy the purple flower spikes.

• Ozark summers swing between heavy storms and dry weeks. Water deeply about once a week only when rain has been missing.
• Established clumps tolerate drought, so do not overwater in the humid stretches.
• Flower spikes rise above the leaves mid to late summer. Leave them so berries can form.
• A thin layer of mulch around clumps keeps roots cooler and holds moisture in shallow rocky soil.
• Plants in full afternoon sun may look bleached in August. That usually greens back up in fall.
• If leaf tips brown, check drainage first, then watering habits.
