When to prune two-ranked aechmea 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 two-ranked aechmea
Trim individual dead or damaged leaves at the base with sterile scissors. Remove the fully spent mother rosette by cutting it away at soil level, taking care not to damage surrounding pups.
Two-Ranked Aechmea requires little pruning. The mother rosette blooms once then gradually dies. Remove yellowing or damaged leaves as they appear using clean scissors or a blade cut close to the base. Once pups (offsets) have grown to roughly one-third the size of the mother, remove the spent rosette cleanly.

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.
