When to prune oregano 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 oregano
Cut stems back by up to half using clean scissors, just above a leaf node. Remove any flowering stems promptly if you want to extend the harvest window for leaves.
Oregano grows vigorously and benefits from regular cutting to keep it productive and prevent it flopping over. Cut stems back by half before or just after flowering to stimulate fresh leafy growth. Regular harvest throughout summer acts as continuous pruning and improves flavour concentration before the plant sets seed.

Pruning oregano in the UK — FAQ
When should I prune oregano in the UK?
Prune oregano 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 oregano in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to oregano, 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 oregano?
Cut stems back by up to half using clean scissors, just above a leaf node. Remove any flowering stems promptly if you want to extend the harvest window for leaves.
How often does oregano need pruning in a British garden?
2–3 times per growing season. Oregano grows vigorously and benefits from regular cutting to keep it productive and prevent it flopping over. Cut stems back by half before or just after flowering to stimulate fresh leafy growth. Regular harvest throughout summer acts as continuous pruning and improves flavour concentration before the plant sets seed.
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.
