When to prune hemigraphis alternata in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune hemigraphis alternata
Trim overlong or straggly stems back to a healthy node using clean scissors. Remove dead or yellowed leaves by pinching them off at the base of the petiole to keep the plant looking tidy.
Hemigraphis alternata (Purple Waffle Plant) is a low-growing tropical foliage plant that spreads along the soil surface. It needs very little pruning. Trim back any stems that have become straggly or are spreading beyond the pot edge, and remove damaged or yellowed leaves as they appear. No structural pruning is required.

Prune hemigraphis alternata in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune hemigraphis alternata in spring or summer in the UK?

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.
