When to prune bell cotyledon 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 bell cotyledon
Cut back leggy or untidy stems by up to one-third with clean, sharp scissors, cutting just above a leaf node. Remove finished flower stalks cleanly at the base.
Bell Cotyledon is a shrubby succulent that can become leggy without occasional shaping. Trim back elongated stems after its tubular flowers fade to encourage bushier growth. Remove spent flower stalks at the base. It tolerates pruning better than most succulents, so light annual shaping keeps the plant tidy and well-branched.

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.
