When to prune macho 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 macho fern
Cut individual dead fronds at the base. For the spring refresh, trim all fronds back by one-third, cutting at the base rather than mid-blade, to promote vigorous, bushy regrowth.
Macho Fern is vigorous and benefits from regular maintenance. Remove dead or brown fronds at the base throughout the year. In early spring, cut the whole plant back by about a third to remove tired growth and encourage a dense flush of large new fronds. Trim long, unruly runners any time.

Pruning macho fern in the UK — FAQ
When should I prune macho fern in the UK?
Prune macho fern in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune macho fern in spring or summer in the UK?

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.
