Troubleshooting
Lace Fern problems — and how to fix them
Lace Fern (Cheilanthes gracillima) 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 from overwatering
The primary cause of failure. Allow soil to dry completely and ensure excellent drainage. Reduce watering in all but the warmest summer months.
Frond tip dieback
If not caused by overwatering, check for salt buildup from hard tap water — flush soil thoroughly with filtered water and switch to rainwater if possible.
Frond drop and wilting
Natural drought response — fronds curl when dry as a protective mechanism. Water thoroughly and fronds typically recover within 24 hours.
Mealybugs or aphids
Inspect frond bases for cottony masses or clusters of insects. Treat with neem oil spray or insecticidal soap, applied carefully to avoid over-wetting.
