When to prune microsorum pteropus 'narrow' 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 microsorum pteropus 'narrow'
Cut dead or yellowing fronds at their base near the rhizome. Detach and reposition leaf-tip plantlets once small root clusters have formed.
Java fern 'Narrow' has slim, elongated fronds and slow growth that rarely calls for pruning. Remove old or deteriorating fronds at the rhizome. Leaf-tip plantlets that form can be detached once rooted and replanted. Avoid trimming healthy fronds — cutting leaves does not promote growth and harms appearance.

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.
