When to prune queen sago 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 queen sago
Cut dead fronds cleanly at the petiole base with sanitized bypass pruners or a small pruning saw. Avoid tearing. Wear gloves — cycad fronds are sharply pointed.
Queen Sago needs minimal pruning — remove only fully dead or damaged fronds at the petiole base. New leaves emerge in periodic flushes; wait until a flush has hardened before removing any older foliage beneath it. Never cut into the trunk or remove the crown. Tidying is the only task; there is no shaping to do.

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.
