Troubleshooting
Purple Cliff Brake Fern problems — and how to fix them
Purple Cliff Brake Fern (Pellaea atropurpurea) 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.
Crown rot
Caused by waterlogged soil or water pooling at the crown. Use gritty mix, ensure excellent drainage, and avoid wetting the centre of the plant.
Frond yellowing
Often indicates overwatering or excessively acid soil. Allow soil to dry well between waterings and verify pH is not below 6.0.
Slow growth indoors
Adapted to outdoor conditions; growth is naturally slow indoors. Provide the brightest indirect light available and avoid overwatering.
Scale insects
Flat brown scales may appear on stems. Remove with a cotton swab dipped in rubbing alcohol and follow up with neem oil.
