Troubleshooting
Cotton Candy Fern problems — and how to fix them
Cotton Candy Fern (Nephrolepis exaltata 'Cotton Candy') 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.
Brown, crispy fronds
The fine foliage browns fast from low humidity or a dry rootball. Keep soil evenly moist and humidity high; trim crisped fronds at the base.
Inner fronds yellowing and shedding
Often overwatering, poor drainage or cold draughts. Improve drainage, let the surface dry slightly between waterings, and move away from vents and cold glass.
Thin, sparse growth
Too little light or spent soil. Move to brighter indirect light and resume diluted feeding to restore the dense, fluffy look.
Spider mites and scale
Dry air invites mites (webbing) and scale (sticky bumps). Rinse fronds, raise humidity, and treat with insecticidal soap; the dense canopy hides pests, so inspect often.
