Troubleshooting
Loranthus-leaf Pleurothallis problems — and how to fix them
Loranthus-leaf Pleurothallis (Pleurothallis loranthophylla) 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.
Crown rot
Water pooling at the base of leaves in low-airflow conditions rapidly leads to crown rot. Always water early in the day, ensure a fan or ventilation is present, and avoid wetting the crown directly.
Leaf yellowing and drop
Can indicate heat stress (temperatures above 26°C), overwatering leading to root rot, or severe underwatering. Check root condition and temperature first. Yellow basal leaves that drop naturally at the bottom of older growth are normal.
Mealybugs
White cottony masses in leaf axils and on roots are a sign of mealybug infestation. Remove manually with rubbing alcohol on a cotton swab, and treat with insecticidal soap or neem oil. Quarantine affected plants immediately.
