When to prune lamb hass avocado in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune lamb hass avocado
Use loppers or a pruning saw to remove upright water shoots and any crossing or dead branches. Head back the tallest scaffold branches by up to one-third to maintain picking height. Avoid removing more than 25% of canopy in one season to prevent sunburn on exposed bark.
Lamb Hass avocado benefits from annual pruning to control height, open the canopy for light penetration, and encourage fruiting wood. Left unpruned, trees become too tall to harvest. Remove crossing branches, water shoots, and head back the main leaders to keep the tree at a manageable 10–15 ft.

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.
