Troubleshooting
Variegated Lilyturf problems — and how to fix them
Variegated Lilyturf (Liriope muscari 'Variegata') 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.
Anthracnose leaf blight
Colletotrichum fungal blight causes reddish-brown lesions with yellow halos, especially in warm, humid conditions. Cut back affected foliage in late winter and avoid overhead irrigation. Improve air circulation; treat with a copper-based fungicide if infection is severe.
Slug and snail damage
Slugs chew through leaves at the base, causing ragged damage particularly on young plants in spring. Apply iron phosphate pellets or a sharp grit barrier around plantings. Nematode treatments are effective in mild, moist conditions.
Loss of variegation in very deep shade
In very dense shade, leaves may revert to producing less defined gold margins and the overall vigour can decline. Move the plant to a brighter (but still shaded) position to restore characteristic variegation and flower production.
