When to prune fritz luth maidenhair fern in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune fritz luth maidenhair fern
Cut dead fronds cleanly at the base. After a full die-back, remove all top growth to soil level, restore humidity above 50%, and water evenly to encourage regrowth from the rhizome.
Adiantum raddianum 'Fritz Luth' needs only light tidying — remove dead or browning fronds at the base with clean scissors. Its delicate, layered fronds should never be trimmed mid-blade. If the plant dies back from low humidity, cut all stems to soil level in spring; the rhizome will usually resprout.

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.
