When to prune deparia acrostichoides in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune deparia acrostichoides
Cut dead fronds cleanly at the base with scissors or hand pruners. Avoid cutting into the crown or disturbing emerging fiddleheads.
Silvery glade fern (Deparia acrostichoides) is a deciduous native fern requiring minimal pruning. Fronds die back naturally in autumn. Remove dead or tattered fronds in late winter or early spring before fiddleheads push through. No structural pruning is needed — just an annual spring tidy is sufficient.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
