Troubleshooting
Wimsett Brake Fern problems — and how to fix them
Wimsett Brake Fern (Pteris cretica 'Wimsettii') 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 frond tips
Most commonly caused by low humidity or under-watering. Raise humidity and maintain consistent soil moisture.
Pale fronds
Insufficient light intensity. Move closer to a window with bright indirect light.
Fungus gnats
Allow the top centimetre of soil to dry slightly between waterings. Use yellow sticky traps to monitor adult populations.
Mealybugs
Inspect the frond bases and crested tips; treat with isopropyl alcohol on a cotton swab.
Loss of crested tips
Occasionally occurs on new growth under stress. Ensure consistent watering, good humidity, and adequate light.
