Heuffel's Houseleek problems — and how to fix them
Heuffel's Houseleek (Jovibarba heuffelii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot from overwatering or winter wet
Sitting moisture at the dense rosette cluster, particularly at low temperatures, causes the centre to blacken and collapse. Ensure grit-based compost, tip containers to drain after heavy rain, and avoid wetting the rosette crown when watering.
Reluctance to divide (mistaken for disease)
Gardeners unfamiliar with J. heuffelii sometimes assume the compact, inward-growing offsets are a problem. This is normal growth. Divide mounds in spring by teasing apart rosettes with a sharp, clean knife and potting individually into gritty mix.
