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 cork palm

Cut dead frond stalks at the base using clean loppers or a pruning saw. Sterilise tools before and after, especially if grown alongside other cycads.

Cork Palm (Microcycas calocoma) is a critically endangered Cuban cycad requiring virtually no pruning. Remove only fronds that are fully dead or badly damaged, cutting cleanly at the frond-stalk base. This species is extremely slow-growing and long-lived — any unnecessary removal of living fronds is detrimental. Treat it as a conservation specimen and disturb it as little as possible.

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.
