Troubleshooting
Twisted Stanhopea problems — and how to fix them
Twisted Stanhopea (Stanhopea anfracta) 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.
Failure to flower in pots
Stanhopea inflorescences grow downward and must exit through the basket base. Planted in solid pots or dense media, flower spikes abort underground. Always use a wide-mesh slatted basket lined with moss, never a solid pot.
Leaf spotting and fungal rot
Large pleated leaves are prone to fungal spotting in stagnant humid conditions. Ensure airflow with a fan, avoid wetting leaves late in the day, and apply a preventive fungicide if leaf spots appear.
Spider mites
Low humidity during winter rest can trigger spider mite infestations, causing silvery stippling on leaves. Increase humidity, mist the undersides of leaves, and treat with insecticidal soap or neem oil.
