When to prune portulaca grandiflora 'sundial mango' 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 portulaca grandiflora 'sundial mango'
If trimming, use scissors to cut trailing stems back lightly by up to one-quarter, just above a leaf node. Do not cut back hard — portulaca dislikes severe pruning.
Portulaca 'Sundial Mango' is largely self-maintaining — flowers open and close with light and drop cleanly without deadheading. Pruning is rarely necessary. If plants become sprawly by midsummer, trim lightly by up to one-quarter to encourage fresh growth. Beyond that, let this drought-tough annual grow with minimal intervention.

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.
