Tree shapes
The form you choose in the first three years sets the tree for decades. Train for permanent structure early, then prune lightly. Most NZ temperate fruit responds best to summer pruning (after harvest) — especially stone fruit, where winter cuts invite bacterial canker and silverleaf.
Central leader free training
Best for: Apples, pears, cherries, plums — most pipfruit on any rootstock
Goal: One strong trunk with well-spaced lateral branches trained near horizontal to encourage fruiting wood.
Timeline
- Year 1: Establish roots. Select 3–4 scaffold branches. Remove competing leaders.
- Years 2–3: Space scaffolds 20–30 cm apart up the trunk. Keep the central leader dominant.
- Year 4+: Maintenance only — remove dead, diseased, crossing, or overly vertical wood.
Five branches to remove (mid-summer)
Remove entire branches rather than heading back — shortening causes water sprouts and delays fruiting.
- Crossing — rub wounds and disease entry points
- Too low — below your clear-trunk height (typically 60–80 cm)
- Too close to trunk — narrow crotches under 45° are structurally weak
- Too vertical — competes with the leader and stays vegetative
- Tired / drooping — old wood that no longer bears quality fruit
Tool hygiene
Sterilise secateurs with methylated spirits between trees. Cut just outside the branch collar — never leave stubs.
Common mistakes
- Over-pruning young trees — removes future fruiting wood and delays the first crop
- Heading back branches — triggers vigorous regrowth instead of fruit buds
- Winter pruning stone fruit — increases canker and silverleaf risk in NZ's mild, wet winters
- Dense centres — poor light and airflow mean fewer fruit and more fungal pressure
- Ignoring the first three years — correcting bad structure on a mature tree is far harder
