When to prune hygrophila corymbosa 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 hygrophila corymbosa
Cut stems horizontally with aquarium scissors at the desired height. Replant the trimmed top section as a new cutting. Pinch growing tips to encourage side shoots. Remove bare lower stems periodically.
Hygrophila corymbosa (temple plant) grows vigorously and needs regular cutting back to stay in bounds and encourage bushy growth. Trim stems to your target height and replant tops as cuttings. Remove lower leaves that yellow or rot. Pinching stem tips promotes lateral branching for a denser appearance.

Pruning hygrophila corymbosa in the UK — FAQ
When should I prune hygrophila corymbosa in the UK?
Prune hygrophila corymbosa in early to mid spring.

Trim stems to your target height and replant tops as cuttings. Remove lower leaves that yellow or rot. Pinching stem tips promotes lateral branching for a denser appearance.
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.
