When to prune guava 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 guava
Train young trees to a single trunk with three to four lateral scaffold branches. On established trees, use thinning cuts to open the canopy, head back long shoots to control spread, and pinch growing tips to encourage bushier, more floriferous growth. Remove suckers at the base throughout the season.
Guava flowers and fruits on new growth, so pruning is genuinely productive — not optional. Annual trimming in late winter encourages vigorous new shoots that carry the season's crop, controls the tree's dense habit, and makes harvest manageable. Suckers and dead wood can be removed any time.

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

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.
