When to prune drosera intermedia 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 drosera intermedia
Use fine-tipped tweezers or small scissors to remove blackened leaves at their base. Avoid disturbing the living rosette or the dew-covered tentacles.
Drosera intermedia, an oblong-leaved sundew, needs very little pruning. Remove dead or blackened leaves as they appear to keep the rosette tidy and discourage rot. Living leaves with active dew are functional — never remove them. In autumn, the plant may die back to a hibernaculum; clear away dead foliage at that point.

Pruning drosera intermedia in the UK — FAQ
When should I prune drosera intermedia in the UK?
Prune drosera intermedia in early to mid spring. 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.
Is it illegal to prune drosera intermedia in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to drosera intermedia, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.
How do you prune drosera intermedia?

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.
