How does the open-centre training system work for peach trees?

The open-centre training system is a method used for trees that respond well to severe annual pruning, such as the peach. This system works by creating a tree structure with a short trunk that supports a scaffold of four or five main branches. These branches then divide multiple times to provide the necessary fruiting wood.

By maintaining an open centre, this training technique ensures that the tree remains relatively small and allows for efficient annual renewal pruning. This structure is particularly beneficial for managing peach trees, as it helps maintain a balance between flowering and leaf surface, improves light exposure for the leaves, and facilitates easier spraying and harvesting operations.1
