Troubleshooting
Western Maidenhair Fern problems — and how to fix them
Western Maidenhair Fern (Adiantum aleuticum) 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.
Crisping fronds
From drying out or dry indoor air. Keep the soil cool and evenly moist and shelter from heat and wind.
Sun scorch
Direct sun damages the fine pinnae. Grow in dappled to full shade or bright indirect light only.
Winter dieback confusion
It is deciduous and dies back over winter, re-sprouting in spring. An empty-looking pot in the cold months is normal, not a dead plant.
Slug damage on new growth
Emerging croziers are vulnerable in spring. Protect with barriers or pet- and wildlife-safe slug controls.
