When to prune pygmy sundew 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 pygmy sundew
Use fine-tipped tweezers or small scissors to remove dead outer leaves at their base without disturbing the central rosette or gemmae (the vegetative buds produced in winter).
Pygmy Sundew is a tiny rosette-forming carnivorous plant that needs virtually no pruning. Simply remove blackened or dead outer leaves as they die back. Do not trim the sticky dew-covered trap leaves — the plant's entire above-ground structure is functional. This species is too small for conventional pruning.

Pruning pygmy sundew in the UK — FAQ
When should I prune pygmy sundew in the UK?
Prune pygmy sundew in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

Is it illegal to prune pygmy sundew in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to pygmy sundew, 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.

This species is too small for conventional pruning.
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.
