Spiny Orostachys problems — and how to fix them
Spiny Orostachys (Orostachys spinosa) 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.
Root rot in wet winters
Even though the plant is extremely frost-hardy, cold and wet soil together are fatal. In the UK and Pacific Northwest, grow in a raised bed, a cold frame in winter, or a well-drained alpine house. If outdoors, slope the planting site for rapid drainage.
Rosette death after flowering
Perfectly normal monocarpic behavior — the rosette dies after its single flowering event (typically in late summer or autumn). Offsets produced earlier in the season carry the plant forward. Save and pot up chicks before the spike appears.
Vine weevil damage
Vine weevil grubs eat the roots from below, causing sudden wilting without obvious above-ground cause. Check the root zone; treat with nematode biological control (Steinernema kraussei) in late summer to early autumn when soil is warm enough.
Prevent spiny orostachys problems before they start
Most spiny orostachys issues are care-mismatch, not bad luck. Dial in the basics:
