CITRUS PRUNING: Pruning techniques for tree health, pest control, fruit production and size control: Tree Shapes • Citrus trees are generally pruned to a central leader or a modified central leader shape. • A full canopy of leaves should be maintained in order to protect the bark of the trunk and scaffold branches from direct sun and potential sunburn. • Trees can have branches close to the ground (have a full skirt) or can have the lower branches pruned off to expose the trunk. • When the lower branches have been removed, the tree is said to be skirted • Multiple trees are sometimes planted together in one hole to produce what appears to be a single tree with multiple trunks. • Although each individual tree will produce less fruit, multiple plantings will result in a greater variety of fruit or in an extended period of fruit harvest in the space of a single tree. • The tree trunks are planted close together and are angled outward at a 30 degree angle from ve...
