When to prune agave parryi 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 parryi
Wearing heavy leather gloves, use sharp loppers or a pruning saw to cut dead outer leaves close to the stem. Remove only what is clearly dead or damaged. The blue-grey rosette is self-symmetrical — do not cut healthy leaves for shaping.
Agave parryi (Parry's Agave) is a compact rosette succulent that requires minimal pruning. Remove dead or desiccated outer leaves flush at the base when they appear. Wear thick gloves — the spines are stiff and sharp. After flowering (monocarpic), cut the tall stalk down once the plant has fully died and dried.

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.
