Troubleshooting
Big Blue Lilyturf problems — and how to fix them
Big Blue Lilyturf (Liriope muscari 'Big Blue') 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.
Leaf tip burn
Usually caused by fluoride in tap water or low humidity. Use filtered water and raise humidity to resolve.
Root rot
Overwatering in poorly draining soil causes crown and root rot. Ensure the pot has drainage holes and allow the top soil to dry between waterings.
Scale insects
Waxy brown scales may appear on stems. Remove manually with a cotton swab dipped in rubbing alcohol and treat with neem oil.
Sluggish growth
Insufficient light is the most common cause. Move to a brighter position out of direct sun.
Yellow leaves
Can indicate overwatering, nutrient deficiency, or natural ageing of outer leaves. Check watering frequency and feed during the growing season.
