Troubleshooting
Broadleaf Stonecrop problems — and how to fix them
Broadleaf Stonecrop (Sedum spathulifolium) 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.
Crown rot in wet winters
The main risk outdoors in wet UK/Pacific Northwest winters. Rosettes blacken and collapse when sitting in waterlogged soil. Plant in raised beds or troughs with deep grit drainage layers, and ensure the crown stays dry. Move container-grown plants under cover in prolonged wet spells.
Vine weevil larvae (outdoors)
Larvae feed on roots, causing plants to wilt and detach from the soil easily. Check the root zone in early autumn. Apply nematodes (Steinernema kraussei) in late summer when soil is warm and moist, or use licensed vine weevil compost treatments.
Loss of waxy silver bloom
Handling the leaves removes the glaucous coating. Avoid touching rosettes unnecessarily when re-potting. The natural bloom also fades under persistently low light — increase sun exposure for best silvery appearance.

Most broadleaf stonecrop issues are care-mismatch, not bad luck. Dial in the basics:
