Sempervivum heuffelii problems — and how to fix them
Sempervivum heuffelii (Sempervivum heuffelii) 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.
Rot from winter wet
Cold combined with soggy soil is the main killer. Ensure extremely sharp drainage and keep nearly dry in winter; remove any mushy, blackened rosettes.
Etiolation indoors
As an alpine it stretches and loses colour in low light and warm rooms. Grow it outside or in the brightest, coolest spot available.
Monocarpic rosette death
A rosette dies after it flowers, which alarms growers. This is normal; the surrounding divisions carry the plant on, so remove only the spent rosette.
Vine weevil and mealybugs
Root-feeding weevil grubs and mealybugs can attack clumps. Check roots when repotting and treat infestations promptly.
