When to prune roosevelt 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 roosevelt fern
Use clean scissors or pruning shears to cut individual dead or yellowed fronds off at the base of the stem, as close to the soil as possible without disturbing the crown. Never cut back healthy green fronds.
Roosevelt Fern needs minimal pruning — remove yellowed, dead, or damaged fronds at the base as they appear. No shaping is required; cutting healthy fronds weakens the plant. Focus on hygiene rather than structure. This cultivar of Nephrolepis exaltata is grown for its naturally arching, ruffled fronds.

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.
