When to prune string of turtles 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 string of turtles
Pinch or snip dead or shrivelled individual stems at the soil level. To tidy an overly long trail, cut the stem back to a node just above healthy turtle-patterned leaves. Use clean, sharp scissors to avoid crushing the fragile stems.
String of Turtles is a slow-growing, delicate trailing peperomia that needs almost no pruning. Simply remove any dead, shrivelled, or rotted stems. If trailing stems become too long or sparse, trim them back to encourage fresh growth from the base. Never cut healthy stems unnecessarily — the plant is slow to recover.

Pruning string of turtles in the UK — FAQ
When should I prune string of turtles in the UK?
Prune string of turtles 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 string of turtles in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to string of turtles, 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 often does string of turtles need pruning in a British garden?
Rarely; only as needed to remove dead growth or trim extreme length. String of Turtles is a slow-growing, delicate trailing peperomia that needs almost no pruning.

Never cut healthy stems unnecessarily — the plant is slow to recover.
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.
