Troubleshooting
Costa Rican Stanhopea problems — and how to fix them
Costa Rican Stanhopea (Stanhopea costaricensis) 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 pot — no blooming
The single most common cause of non-flowering in Stanhopea is growing in a solid pot. Spikes grow downward and are blocked by solid walls or bases, rot, and fail to emerge. Always use an open slatted wooden or wire basket. If this mistake has been made, repot immediately into a basket.
Pseudobulb shrivelling
Caused by root loss (from rot or desiccation) or insufficient watering during active growth. Inspect roots at repotting — healthy roots are plump and white-green. If root rot is found, trim affected roots, dust with cinnamon or fungicide, and repot into fresh sphagnum.
Spider mites and thrips
The large, soft pleated leaves are attractive to spider mites (especially in low humidity) and thrips. Both cause stippling, silvering, or streaking of leaves. Maintain high humidity, inspect leaf undersides regularly, and treat with insecticidal soap, neem oil, or a registered miticide.
