Crested Silver Lady Fern problems — and how to fix them
Crested Silver Lady Fern (Blechnum gibbum 'Silver Lady') 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 frond tips
Most commonly caused by low humidity or fluoride in tap water. Use rainwater or filtered water and raise ambient humidity.
Yellowing fronds
Can signal overwatering, poor drainage, or excessively cool temperatures. Check roots for rot and ensure the pot drains freely.
Scale insects
Appear as brown waxy bumps on fronds and stems. Remove manually with isopropyl alcohol and treat with neem oil.
Frond die-back in winter
Normal in low light and cool conditions. Remove dead fronds and reduce watering; new fronds emerge in spring.
Crown rot
Results from watering directly into the crown or poor air circulation. Water at soil level and ensure good ventilation.
