cultivated tree form (fruit trees)
Tree forms for top fruit trees are developed and maintained by training and pruning (including heading back), and are broadly divisible into two-dimensional forms including the cordon, step-over, espalier and fan, and three-dimensional forms. Three-dimensional forms either have a centre leader or an open centre.
