Japanese Painted Fern 'Pictum' problems — and how to fix them
Japanese Painted Fern 'Pictum' (Athyrium niponicum var. pictum) 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.
Crisped, browning frond edges
From dry soil or low humidity. Keep the soil evenly moist, raise humidity indoors, and shelter from hot sun and drying wind.
Faded, washed-out colour
Too much direct sun bleaches the silver and burgundy; too little light dulls it. Bright dappled shade gives the richest markings.
Complete winter die-back
Normal for this deciduous fern. Fronds collapse in autumn; cut them away, keep the crown lightly moist, and it reshoots in spring.
Slug and snail damage outdoors
Young spring fronds are a target. Use barriers or wildlife-safe controls around emerging crowns.
