When to prune dryas primulina 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 dryas primulina
Snap or cut spent flower scapes cleanly at the base. Gently peel or cut off yellowed outer leaves flush with the rosette crown to prevent rot.
Primulina dryas needs very little pruning. Simply remove spent flower stalks at the base once blooms finish, and peel away any yellowed or dead outer leaves. The compact rosette form is self-regulating — do not cut into healthy foliage. Beyond dead-heading and leaf hygiene, no structural pruning is required.

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.
