When to prune grigua 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 grigua cycad
Cut dead fronds flush to the trunk base with clean, sterilised pruning shears. Wipe blades with isopropyl alcohol before and after use to prevent disease spread.
Grigua Cycad (Encephalartos cycadifolius) is a slow-growing South African mountain cycad requiring almost no pruning. Remove only dead, yellowed, or damaged fronds by cutting at the trunk base. Healthy fronds support the plant's energy reserves over many years — leave them untouched. No shaping or size reduction is appropriate.

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.
