When to prune red riding hood mandevilla 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 red riding hood mandevilla
Pinch or snip stem tips back by 2 to 4 inches above a leaf node to promote branching. Remove any dead or crossing growth. Do not hard-prune — this cultivar's compact form is its main ornamental trait.
Red Riding Hood is a compact, bushy Dipladenia cultivar rather than a vigorous climber — its mounding habit means it needs far less pruning than vining types. Light tip-pinching encourages fullness and more blooms. Avoid heavy cutbacks that destroy the natural form. Milky sap is a skin irritant; use gloves.

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.
