Trembling Brake Fern problems — and how to fix them
Trembling Brake Fern (Pteris tremula) 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.
Frond drop
Caused by underwatering, temperature shock, or sudden environmental change. Maintain consistent moisture and temperature.
Brown frond tips
Low humidity or dry air. Increase humidity with a pebble tray or humidifier.
Pale, leggy growth
Insufficient light. Move to a brighter location with indirect light.
Fungus gnats
Larvae thrive in continuously moist topsoil. Allow the very top layer to dry slightly between waterings and use yellow sticky traps.
