Troubleshooting
Splendid Anthurium problems — and how to fix them
Splendid Anthurium (Anthurium splendidum) 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.
Root rot from overwatering
The most common killer; soggy or compacted substrate suffocates the roots and causes mushy, blackened roots and wilting. Use a chunky, free-draining mix, let the top of the substrate dry between waterings, and never leave the pot sitting in water.
Deformed or browning new leaves from low humidity
Below roughly 70-80% humidity the bullate leaves emerge small, flat, or crinkled and edges brown. Move the plant into a terrarium, cabinet, or enclosed case with consistently very high humidity to fix it.
Spider mites
Dry air and warmth invite mites, seen as fine webbing, stippling, and dull leaves. Rinse the foliage, raise humidity, and treat with insecticidal soap or neem oil, repeating every few days until clear.
Bacterial blight
Water-soaked yellow lesions that turn brown or black, spreading fast in warm, wet, stagnant conditions. Remove affected leaves, improve air circulation, avoid overhead wetting and overwatering, and isolate the plant.
Leaf scorch from direct sun
Direct sunlight bleaches and burns the delicate leaves, leaving crispy tan or brown patches. Move it to bright indirect light or add a sheer curtain to diffuse strong sun.
Fertilizer salt burn
Over-feeding or salt buildup browns the sensitive root tips and leaf margins. Feed at half strength during the growing season and flush the substrate with plain water periodically to leach out excess salts.
