When to prune lance-leaved 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 lance-leaved sundew
Pull or snip dead leaves away at the base of the rosette using clean, fine-tipped scissors. If removing flower scapes, cut at the base. Take care not to disturb the shallow root system or the living sticky leaves surrounding the crown.
Drosera adelae requires very little pruning. Simply remove any dead or fully browned leaves by pulling them gently free from the crown. Flower stems can be left to self-seed freely (this species spreads readily via root cuttings) or removed to direct energy into the rosette. No other pruning is needed.

Pruning lance-leaved sundew in the UK — FAQ
When should I prune lance-leaved sundew in the UK?
Prune lance-leaved sundew in spring, once growth resumes. 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.
Is it illegal to prune lance-leaved sundew in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to lance-leaved 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.
How do you prune lance-leaved sundew?
Pull or snip dead leaves away at the base of the rosette using clean, fine-tipped scissors. If removing flower scapes, cut at the base. Take care not to disturb the shallow root system or the living sticky leaves surrounding the crown.
How often does lance-leaved sundew need pruning in a British garden?
As needed — very infrequent; tidy when dead growth is visible. Drosera adelae requires very little pruning. Simply remove any dead or fully browned leaves by pulling them gently free from the crown. Flower stems can be left to self-seed freely (this species spreads readily via root cuttings) or removed to direct energy into the rosette. No other pruning is needed.
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.
