When to prune agave zebra 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 zebra
Use heavy bypass shears and thick gloves to cut dead outer leaves flush to the base. After flowering, remove the entire spent rosette at soil level.
Agave zebra is a low-maintenance rosette that needs almost no pruning. Remove dead or damaged outer leaves at the base as they dry out. Its bold, banded leaves are ornamental — never shorten or trim green leaves. Like all agaves, it is monocarpic, so the rosette is removed only after it flowers and dies.

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.
