When to prune kalanchoe 'calandiva' 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 'calandiva'
Pinch or cut spent flower heads back to the nearest leaf node. After flowering, shorten any leggy stems by up to one-third using clean scissors. To rebloom, give the plant 6 weeks of 14-hour dark nights after trimming.
Kalanchoe 'Calandiva' benefits from deadheading to encourage reblooming. Pinch or snip off spent flower clusters at the stem junction once they fade. After a full bloom cycle, cut leggy stems back by about one-third to keep the plant compact. Beyond that, it needs very little pruning — just remove dead or damaged leaves.

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.
