When to prune super king ixora red 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 super king ixora red
Hand-prune by cutting just above a leaf node or lateral shoot after flower clusters fade. Remove any dead or crossing branches at the base. If the shrub is overgrown, cut back by up to one-third in early spring before the main growing season, not mid-bloom.
Ixora 'Super King' is a large-flowered tropical shrub that blooms on new growth. Light pruning after each flowering flush encourages repeat blooming and prevents legginess. Avoid excessive shearing with hedge trimmers, which removes flower buds. A light thinning and tip-prune by hand gives far better results than a mechanical flat-top cut.

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.
