When to prune cuban 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 cuban oregano
Pinch out the top 2–3 cm of each stem tip regularly to encourage branching. If the plant has become leggy, cut stems back by up to one-third with clean scissors just above a leaf node. Cuttings root easily in water.
Cuban Oregano (a succulent-leaved Plectranthus, not a true oregano) grows vigorously and responds well to regular pinching to stay bushy and prevent legginess. Pinch growing tips whenever stems get lanky. Cutting back by one-third if the plant becomes sprawling keeps it compact. It tolerates hard pruning and bounces back readily.

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

Is it illegal to prune cuban oregano in spring or summer in the UK?

Pinch growing tips whenever stems get lanky. Cutting back by one-third if the plant becomes sprawling keeps it compact. It tolerates hard pruning and bounces back readily.
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.
