When to prune trailing clog plant 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 trailing clog plant
Use clean scissors to trim trailing stems back by up to one-third, cutting just above a leaf node. Remove bare or dead stems at the base. Avoid drastic cuts — Nematanthus is slow to regrow from bare wood, so always cut back to where leaves are present.
Trailing clog plant (Nematanthus radicans) is a cascading houseplant bearing small, pouch-like orange flowers. It benefits from a light trim after flowering to prevent legginess and stimulate new blooming growth. Cut stems back by one-quarter to one-third. Beyond annual post-bloom tidying and removal of dead stems, little pruning is needed.

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.
