When to prune pseuderanthemum carruthersii 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 pseuderanthemum carruthersii
Cut stems back by up to one-third using clean, sharp scissors or pruning shears. Pinch soft tips throughout the season to encourage branching and fuller growth.
Pseuderanthemum carruthersii is a tropical shrub that benefits from light pruning to maintain a tidy, bushy shape. Without trimming it can become leggy. Pinch growing tips in spring and cut back longer stems after any flowering flush to promote dense, colourful foliage growth and prevent bare lower stems.

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.
