Troubleshooting
Silver Brake Fern problems — and how to fix them
Silver Brake Fern (Pteris argyraea) 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.
Loss of silvery variegation
Variegation fades in low light. Move the plant to a brighter position with more indirect light to restore the characteristic white frond stripe. Avoid direct sun which bleaches the colour in a different, damaging way.
Brown frond tips and edges
Low humidity or underwatering. Raise ambient humidity above 50%, water more consistently, and mist the fronds regularly. Accumulated fertiliser salts in the compost can also cause tip burn — flush the pot with clean water periodically.
Root rot and wilting despite watering
Caused by compacted, waterlogged soil. Repot into fresh, free-draining compost with extra perlite; trim rotted roots back to healthy tissue. Ensure the pot has drainage holes and never sits in a saucer of standing water.
