Frohnleiten Epimedium problems — and how to fix them
Frohnleiten Epimedium (Epimedium × perralchicum 'Frohnleiten') 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.
Worn evergreen leaves
Old foliage can look battered by late winter. Cut it back in late February to reveal fresh growth and the spring flowers.
Vine weevil
Root-feeding larvae can damage plants, particularly in containers. Check roots and use nematode biocontrol if grubs are present.
Slow initial spread
It establishes gradually before spreading vigorously. Keep watered and mulched during the first season.
Reduced flowering in dense shade
Very dark, dry sites curb bloom. Enrich the soil and provide some indirect light for the best flower display.
