Troubleshooting
Green Cliff Brake Fern problems — and how to fix them
Green Cliff Brake Fern (Pellaea viridis) 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
The most common problem — caused by overwatering or poor drainage. Allow the soil to dry partially between waterings and ensure the pot drains freely.
Frond tip browning
May indicate under-watering or excessively dry air. Water when the upper half of soil is dry and increase humidity slightly.
Yellowing fronds
Often due to overwatering or low light. Check drainage and move to a brighter location.
Mealybugs
Check frond bases and stem junctions for white cottony masses. Remove manually and apply insecticidal soap or diluted neem oil.
