Troubleshooting
Royal Purple Lilyturf problems — and how to fix them
Royal Purple Lilyturf (Liriope muscari 'Royal Purple') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown and root rot
Soggy, poorly drained soil rots the crown — the most common cause of failure. Plant in well-draining soil and avoid overwatering, particularly in containers.
Weathered winter foliage
Evergreen leaves can brown and look tatty after a cold winter. Cut the entire clump back hard in early spring just before fresh growth emerges.
Slug and snail damage
Tender spring shoots are grazed by slugs and snails. Protect emerging growth with barriers, traps or evening removal.
Few flowers in deep shade
Very shaded plants grow lush but produce little of the prized purple bloom. Give some direct sun to maximise flowering.
