When to prune restrepo's chigua 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 restrepo's chigua
Cut dead frond rachises cleanly at the base with sterilised loppers or pruning shears. Minimal intervention is the guiding principle for this conservation-grade specimen.
Restrepo's Chigua (Chigua restrepoi) is a critically endangered Colombian cycad. It needs essentially no pruning — remove only fronds that have entirely died back, cutting at the base of the frond stalk. As an extremely rare species, this plant should be disturbed as little as possible. Never remove green or partially live fronds under any circumstances.

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.
