Troubleshooting
Pyrenean Ramonda problems — and how to fix them
Pyrenean Ramonda (Ramonda myconi) 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.
Rosette rot in winter
The most common cause of death: moisture accumulates in the rosette during wet winters and causes rapid rotting. Grow plants nearly vertical in rock crevices or raised beds, and protect with an open-sided cloche in climates with prolonged winter wet.
Slugs and snails
The hairy leaves are highly attractive to slugs, especially in damp conditions. Use copper tape barriers around pots, crushed grit mulch at the base, or organic slug pellets in a rock garden setting.
Failure to flower
Insufficient chilling in winter can prevent flowering in warm climates. Plants need cold winter dormancy to set flower buds. Ensure they experience temperatures close to or below freezing during their winter rest.
