When to prune agave geminiflora 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 geminiflora
Use gloves and thin-tipped scissors or pruners to carefully cut or pull dead outer leaves from the base of the rosette. Work slowly between the dense narrow leaves to avoid breaking healthy foliage.
Agave geminiflora (Twin-Flowered Agave) is a fine-leaved, globe-forming rosette that requires almost no pruning. The hundreds of narrow leaves self-clean, and dead outer ones can be gently pulled or cut away. Do not trim for shape — the globe form is natural. Wear gloves; tips are sharply pointed. Remove spent flower stalks after bloom.

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.
