When to prune golden tree 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 golden tree fern
Sever dead fronds cleanly at the base, close to the trunk. Leave the fibrous trunk undisturbed and never trim the crown or actively growing fronds.
Golden Tree Fern (Dicksonia fibrosa) needs minimal pruning. Remove only completely dead, brown fronds by cutting them at the base of the trunk. Like all tree ferns it has a single growing point at the crown — cutting into it is fatal. Fronds should be left to die fully before removal to allow nutrient reabsorption.

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.
