Leaf order refers to the arrangement order of leaves (or axillary buds) of fruit trees on branches. Different kinds of fruit trees have different leaf orders; The order of leaves sometimes changes with different tree potentials. Apple trees and most other fruit trees are 2/5-shaped, that is, two adjacent leaves (or axillary buds) account for 2/5 of the circumference of branches.

The leaf order of fruit trees plays a very important role in the shaping and pruning of fruit trees. The shape of apple trees is scattered and layered. When choosing three main branches at the base, we must choose three suitable directional buds. The best way is to choose them according to the leaf order. After determining the location of 1 bud, the second directional bud should be selected in the 7th section of 1 bud, and the third directional bud should be selected in the 3rd section of 1 bud. The selected bud branches can basically ensure that there is an included angle of 120 degrees between the three main branches at the base, and the phenomenon of neck sticking will not be formed.
