Pruning Fruit Trees

The brief version of Margaret Siri's series on the ABC (circa 2010) about pruning fruit trees: Gardening Online With Margaret Siri

Apricots
Prune back to the fruiting spur
Fruiting spur is usually a trio of buds
Check for end fruiting spurs on softer branches
Prune dead material
Bring down height of tree so fruit can be reached, remove crossover branches in the middle - trim back to a fruiting spur, encourage fruiting spurs to grow thicker by having them at the end.
Spray with lime sulphur after

Peach & Nectarine
Bring the height down, trim off dead and dying
Fruiting spurs have multiple buds (2 or 3)
Trim back to a fruiting spur (check for multiple spurs)
Spray with lime sulphur after pruning (before bud swell)

Apples
Fruiting spur on an apple is pretty thin and not so clumped.
Cut just behind a growth spur, forming a short stub for the fruit to appear
Thin out shoots that are too near to the trunk, and any little pieces that have died.
Cut back to a stub, control heigh and growth, clear centre of tree, and encourage fruiting spurs to form each year rather than growth.

Japanese Plums - Blood and Golden
Try to promote new growth each year.
Small shoots are the fruiting spurs. Double and triple buds are fruiting buds.
New growth has small growth buds. To encourage growth, cut ahead of growth buds in direction to grow.
To encourage fruiting, cut behind growth buds.
Take off old wood to encourage new wood.
