When to prune lacandon zamia 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 lacandon zamia
Remove dead or yellowed fronds by cutting cleanly at the trunk base with sterile pruners. Never cut into the central crown or caudex.
Lacandon Zamia (Zamia lacandona) needs minimal pruning. This rare tropical cycad benefits only from removal of dead, yellowed, or damaged fronds. Do not attempt to shape or reduce healthy growth — cycads do not regenerate from hard cuts and pruning healthy tissue causes unnecessary stress.

Pruning lacandon zamia in the UK — FAQ
When should I prune lacandon zamia in the UK?
Prune lacandon zamia in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

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.
