Sempervivum 'Emerald Empress' problems — and how to fix them
Sempervivum 'Emerald Empress' (Sempervivum 'Emerald Empress') 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.
Winter wet rot
Cold, soggy soil rots the rosettes far more readily than frost itself. Ensure very sharp drainage and keep nearly dry through winter, especially in pots.
Etiolation indoors
Grown inside without intense light, rosettes loosen and lose colour. It performs best outdoors; if kept indoors, give it the sunniest possible spot.
Parent dies after flowering
Each rosette is monocarpic and dies once it blooms. This is normal, not disease; simply remove the spent rosette and let the surrounding chicks fill in.
Vine weevil and mealybugs
Weevil grubs chew roots in pots and mealybugs hide between offsets. Check roots when repotting and treat pests promptly to protect the colony.
