When to prune kalanchoe pumila 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 kalanchoe pumila
Remove spent flower stalks cleanly at the base. For leggy stems, cut back to a healthy leaf node using clean scissors to encourage denser, more compact regrowth.
Flower dust plant is a compact, low-growing succulent that rarely needs hard pruning. Deadhead spent flowers by cutting the stalk to the base to extend the display. Trim any leggy or straggly stems lightly in spring to maintain a tidy, mounding shape.

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.
