Troubleshooting
Cretan Brake Fern problems — and how to fix them
Cretan Brake Fern (Pteris cretica 'Albolineata') 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, crispy frond tips or edges
Almost always low humidity, underwatering, or proximity to a radiator. Raise humidity with a pebble tray or humidifier and keep the soil evenly moist.
Whole fronds browning and drying out
The rootball has dried out too far. Soak the pot thoroughly and never let this fern dry completely; it does not bounce back from severe drought like tougher houseplants.
Yellowing fronds
Usually overwatering or soggy, poorly drained soil. Let the top inch dry before rewatering, ensure the pot drains freely, and never leave it in standing water.
Scorched, bleached, or pale patches
Too much direct sun on the thin fronds. Move to bright indirect light or partial shade.
Pests: spider mites, mealybugs, scale and aphids
Dry air invites spider mites (fine webbing, stippling). Wipe fronds, raise humidity, and treat with insecticidal soap; ferns can be sensitive, so spot-test and avoid oily or harsh sprays.
Fronds bruise and brown where handled
The delicate fronds mark easily. Site the plant where it won't be brushed against, and handle by the pot rather than the foliage.
