When to prune tillandsia polystachia 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 tillandsia polystachia
Trim brown leaf tips diagonally with clean scissors. Once the mother plant has finished flowering, cut or gently pull away the dried bloom spike. Separate pups when they reach about half the mother's size.
Tillandsia polystachia is an air plant that needs almost no pruning. Simply remove dead or brown leaf tips by trimming with clean scissors, cutting at an angle to maintain a natural look. After the plant flowers and begins to decline, remove the spent bloom spike. Focus on the pups that will replace the mother.

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.
