Troubleshooting
Wildwood Twist Painted Fern problems — and how to fix them
Wildwood Twist Painted Fern (Athyrium niponicum 'Wildwood Twist') 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.
Slug damage to new fronds
Emerging spring fronds are particularly vulnerable to slugs and snails, which leave ragged holes or can destroy whole fiddleheads. Apply organic iron phosphate slug pellets around the crown in spring, and inspect regularly at night.
Loss of silver colouration
The distinctive silver variegation fades to plain green in deep shade. Move to a position with gentle dappled or indirect bright light to restore the characteristic silver-grey tones of the twisted fronds.
Frond die-back in winter
This cultivar is deciduous — fronds yellow and collapse in autumn, which is entirely normal. Cut back to the crown in late autumn or early spring before new growth emerges. The plant re-sprouts reliably each spring.
