When to prune old world sago cycad 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 old world sago cycad
Use sharp, sterilised pruning shears or loppers to cut dead fronds flush with the trunk base. Do not pull or tear fronds, as this can damage the trunk.
Old World Sago Cycad rarely needs pruning. Remove only fully brown or dead fronds by cutting them cleanly at the base. Never cut green or yellowing fronds early — cycads are slow growers and each frond is valuable. Avoid trimming the central growing point, which would permanently damage or kill the plant.

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.
