When to prune agave nizandensis 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 agave nizandensis
Cut dead outer leaves at their base with clean shears, as close to the stem as possible. Wear gloves — even on smaller-statured agaves the terminal spine can cause injury.
Agave nizandensis is a rare, compact Mexican agave that needs very little pruning in cultivation. As with all agaves, simply remove dead or browning outer leaves at the base when they appear. Do not attempt to shape the rosette. Its naturally tight, symmetrical form requires no intervention to stay attractive.

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.
