UK pruning guide · RHS timing
When to prune agave tequilana in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune agave tequilana
Cut dead outer leaves flush to the stem with a pruning saw or serrated blade — the leaves are large and fibrous. Remove pups by exposing the rhizome and cutting cleanly; let the cut surface callous for 24 hours before potting in dry mix.
Agave tequilana (Blue Agave) grown as a container plant needs minimal pruning. Remove dead or damaged outer leaves at the base. In garden settings, lower leaves naturally dry and can be cut away. Pups (hijuelos) develop regularly and are typically removed to keep the parent plant vigorous and for propagation.

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.
