The ring shaped fruiting zone is about four feet wide and four feet deep. The fruiting zone of an open center tree can be thought of as a doughnut supported by scaffold branches. Light penetrates only about three or four feet into the tree canopy. Leaves intercept light and the biochemical reaction, called photosynthesis, light energy is used to produce carbohydrates that are used for growth of all parts of the tree. This more uniform architecture is adaptable to tighter in row tree spacings, which can result in improved yields for the first several years and increased opportunities for mechanization. The natural tree form of a standard type peach tree is a vase shape making it easy to train trees to an open center system with three or four primary scaffold branches.Ī modification of the vase is a V shape with two to four scaffold branches. However, with judicious pruning, standard trees can be maintained at a height of seven or eight feet. The lack of suitable dwarfing rootstocks limits the extent of orchard intensification.
Peach trees are pruned to maintain tree size and shape and to help manage light and crop load.
