Mary's Prosthechea problems — and how to fix them
Mary's Prosthechea (Prosthechea mariae) 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 bloom
Omitting the cool dry winter rest is the main cause. Provide a 6-8 week period with reduced watering and cooler nights.
Root rot
Caused by dense potting medium or overwatering. Repot into fresh bark every 2-3 years and ensure fast drainage.
Pseudobulb shrivelling
Indicates underwatering or root loss. Check root health and adjust watering accordingly.
Fungal leaf spots
Stagnant humid air, especially in winter. Improve ventilation and remove affected tissue with sterilised scissors.
Mealybugs
Hide in pseudobulb sheaths. Treat early infestations with 70% isopropyl on a cotton bud; larger infestations with systemic insecticide.
