When to prune clivia in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune clivia
Cut the spent flower stem as close to the base as possible using clean, sharp scissors or secateurs. Pull away or cut off individual yellowed leaves at the lowest point where they meet the plant base.
Clivia requires minimal pruning. After flowering, cut the spent flower stalk down to the base once blooms fade, to redirect energy away from seed production. Remove any yellowed or damaged leaves at the base. Beyond deadheading stalks, clivia does not need shaping or structural pruning.

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.
