When to prune ceratozamia mexicana 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 ceratozamia mexicana
Use sharp, clean loppers or heavy-duty scissors to cut the dead frond petiole close to the stem. Wear gloves as leaflets can be sharp-tipped. Leave all green and semi-green fronds undisturbed on the plant.
Ceratozamia mexicana is a shade-loving Mexican cycad that requires very little pruning. Remove only fully brown, dead fronds, cutting cleanly at the petiole base. Green fronds must never be removed — they are essential energy stores for this slow-growing plant. Its graceful arching fronds are the main ornamental feature and should be left intact.

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.
