Martius's Stanhopea problems — and how to fix them
Martius's Stanhopea (Stanhopea martiana) 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.
Flower spikes trapped in medium
If not grown in a slatted basket, pendant spikes cannot emerge and flowers rot underground. Always use an open wooden or wire basket and inspect the base of pseudobulbs in late spring for emerging spikes.
Root rot from poor drainage
Heavy, slow-drying media causes root loss. Use an open, fast-draining bark mix, ensure baskets have wide gaps, and increase air circulation. Never let plants sit in standing water.
Spider mites in dry conditions
Low humidity encourages spider mite infestations on the undersides of leaves. Maintain 50%+ humidity, improve airflow, and treat with insecticidal soap or neem oil at the first sign of stippling.
