When to prune agave guiengola 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 guiengola
Use a sturdy pruning saw or heavy knife with gloves to cut dead outer leaves at the base. For pups, expose the rhizome connection and cut cleanly; callous the cut for 24 hours before potting. Avoid disturbing the central rosette.
Agave guiengola is a large-growing agave from Oaxaca, Mexico, that needs minimal pruning. Remove dead or damaged outer leaves at the base as they dry down. Its broad, glaucous leaves and architectural form are best left natural. It may produce basal pups that can be removed 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.
