Athyrium niponicum 'Ursula's Red' problems — and how to fix them
Athyrium niponicum 'Ursula's Red' (Athyrium niponicum 'Ursula's Red') 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.
Washed-out colour
Excess sun bleaches the silver and red while deep shade mutes the maroon. Position in bright dappled shade for the boldest colour.
Drought scorch
Soft fronds crisp and brown if the soil dries out. Maintain even moisture and a leaf-mould mulch; never let containers dry through.
Slug damage to new growth
Slugs and snails graze the tender unfurling fronds in spring. Use wildlife-safe deterrents around emerging croziers.
Frost nip on spring croziers
Newly emerging fronds are vulnerable to late frosts. Shelter the plant or fleece it during cold spells; it normally produces fresh fronds afterwards.
