When to prune congo 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 congo cycad
Use sharp, sterilised loppers or secateurs to remove dead fronds cleanly at the base near the caudex. Avoid tearing, which can damage the trunk.
Congo Cycad needs minimal pruning. Only remove fronds that are completely dead or severely damaged. This large African cycad is extremely slow-growing and stores nutrients in its fronds — removing green leaves weakens it significantly. Beyond clearing dead material, no pruning is necessary or beneficial. Let the plant grow naturally.

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.
