When to prune codonanthe crassifolia 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 codonanthe crassifolia
Pinch or cut stem tips back by one-quarter to one-third to stimulate lateral branching. Cut dead or overly long trailing stems back to a healthy node or to the base. Use clean scissors or pruning snips.
Codonanthe crassifolia is a trailing gesneriad that benefits from light pruning to keep it bushy and encourage flowering. Pinch back long, bare stems after flowering to promote branching. Remove any dead or weak stems at the base. It grows vigorously and tolerates moderate trimming without issue.

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.
