Troubleshooting
Rowlee's Pleurothallis problems — and how to fix them
Rowlee's Pleurothallis (Pleurothallis rowleei) 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.
Wilting in heat
Despite its broad elevation tolerance, sustained temperatures above 28°C in summer cause rapid wilting as the plant lacks water-storage pseudobulbs. Increase watering frequency and shade levels; use a fan for airflow during heat events.
Root rot from overwatering in winter
Lower temperatures slow evaporation, making it easy to overwater. Reduce watering frequency in cooler months while keeping the medium barely moist. Ensure pots drain freely and never sit in standing water.
Fungal spotting
Purple-brown lesions on leaves indicate Botrytis or bacterial infection, common when airflow is poor. Remove affected leaves with sterile scissors and treat with a copper-based or systemic fungicide; improve ventilation immediately.
