Types of Cuts

Heading Cut

Remove part of the branch

Stimulate bud break near cut

Stimulate localized branching

Page 14: Fruit Trees Pruning and Training - Professor · Summer pruning apples and pears allows sunlight to ripen the fruit and ensures good cropping the following year Pinching competitive

Inhibits lateral bud break

Inhibits lateral shoot growth

Affects branch angle

Page 15: Fruit Trees Pruning and Training - Professor · Summer pruning apples and pears allows sunlight to ripen the fruit and ensures good cropping the following year Pinching competitive

Types of Cuts

Remove branch at point of origin

Least invigorating cut

Promote light penetration into canopy
