Troubleshooting
dryas primulina problems — and how to fix them
dryas primulina (Primulina dryas) 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
Water sitting in the rosette center or on hairy leaves causes rapid crown rot, especially in cool conditions. Always water at the base of the plant and ensure temperatures stay above 10°C.
Botrytis (grey mold)
Poor air circulation combined with high humidity in a terrarium can encourage Botrytis fungus. Ensure gentle ventilation, remove any dead leaves promptly, and avoid overly dense planting.
Failure to bloom
Insufficient light or skipped cooler rest period prevents flowering. Provide a cooler winter rest (10–15°C) with reduced watering, then resume warmth and feeding in spring to trigger blooming.
