Douglas's Sinningia problems — and how to fix them
Douglas's Sinningia (Sinningia douglasii) 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.
Spider mites in dry indoor air
Low humidity encourages spider mite infestations on the felty leaves; maintain humidity above 50%, mist the surrounding area (not directly on flowers), and treat early infestations with insecticidal soap or neem oil.
Stem collapse from root rot
Waterlogged compost rapidly rots the tuber and roots, causing sudden stem collapse; use a free-draining mix, ensure the pot has drainage holes, and never let the plant stand in water.
