When to prune pineapple guava in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune pineapple guava
For a tree form, remove lower branches and select 3–5 main scaffold limbs. For hedge use, shear to shape after fruiting. Always remove dead, damaged, and inward-crossing branches first, then reduce overall size as desired.
Pineapple guava tolerates heavy pruning and can be trained as a hedge, espalier, or small tree. Annual light shaping after fruiting keeps size in check. For a natural shrub form, minimal pruning is needed — just remove dead wood and crossing branches. It tolerates hard renovation pruning if required.

When should I prune pineapple guava in the UK?
Prune pineapple guava in mid to late spring. RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
Is it illegal to prune pineapple guava in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check pineapple guava for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
