When to prune macadamia 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 macadamia
Remove dead, diseased, and inward-growing branches first. Then thin crossing branches and any that are shading the interior. Make clean cuts at a 45-degree angle just outside the branch collar. Aim to keep the tree to a manageable picking height of 4–5 m for home orchards.
Macadamia integrifolia benefits from light annual pruning to open the canopy, improve airflow, and maintain a manageable harvest height. Prune after harvest in late winter before the next flush of growth. Remove no more than 25% of the canopy in one season — heavy cutting delays cropping. Macadamias bear on current-season growth, so excessive removal directly reduces yield.

Pruning macadamia in the UK — FAQ
When should I prune macadamia in the UK?
Prune macadamia 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 macadamia in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to macadamia, 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 macadamia?
Remove dead, diseased, and inward-growing branches first. Then thin crossing branches and any that are shading the interior. Make clean cuts at a 45-degree angle just outside the branch collar. Aim to keep the tree to a manageable picking height of 4–5 m for home orchards.
How often does macadamia need pruning in a British garden?
Annually, after each harvest. Macadamia integrifolia benefits from light annual pruning to open the canopy, improve airflow, and maintain a manageable harvest height. Prune after harvest in late winter before the next flush of growth. Remove no more than 25% of the canopy in one season — heavy cutting delays cropping. Macadamias bear on current-season growth, so excessive removal directly reduces yield.
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.
