Troubleshooting
Chinese Brake Fern problems — and how to fix them
Chinese Brake Fern (Pteris multifida 'Cristata') 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.
Crispy or brown crested tips
The crested frond tips are prone to browning in low humidity or when watered with hard tap water. Use rainwater and raise humidity.
Pale, etiolated growth
Insufficient light causes stretched, pale fronds that lack the decorative crested structure. Move to a brighter indirect light position.
Root rot
Results from overwatering or compacted soil. Use a free-draining mix and allow the top of the soil to dry slightly before rewatering.
Mealybugs
White cottony deposits at frond bases and in the crown. Treat with isopropyl alcohol and follow up with neem oil.
Frond loss in winter
Normal in cool, low-light conditions. Reduce watering, maintain temperatures above 10°C, and new fronds will emerge in spring.
