Hairy Raphionacme problems — and how to fix them
Hairy Raphionacme (Raphionacme hirsuta) 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.
Tuber rot during dormancy
The caudex will rot if kept moist when dormant in winter. Cease all watering from the time leaves yellow and drop; resume only when new growth appears in spring. Keeping the tuber partially exposed above the soil surface aids air circulation and reduces rot risk.
Cultivation holes in the tuber
Physical damage to the tuber from rough handling, excessive sun exposure when fully bare, or pest (rodent) attack can create entry points for rot. Handle repotting carefully and ensure the tuber is partially but not excessively exposed.
Failure to emerge in spring
If temperatures are too cool (below 12°C) or the plant has been over-dried for too long, it may be slow to break dormancy. Ensure overwintering temperatures stay above 12°C and resume light watering as temperatures warm in spring.
