A Japanese tree is a low growing deciduous variety that reaches a height of 25 feet with a crown spread of 25 feet. The crown forms a rounded vase shape that benefits from an annual pruning session. Prune Japanese trees during the late summer or early fall months, as this allows the tree to heal during the dormant months. Do not remove more than one-third of the tree growth during a pruning session to prevent excess stress on the tree.
Prune the Japanese tree by cutting off any dead, diseased or damaged branches from the tree with a pruning saw.
Prune off internal branches that cross or rub on each other with a pruning saw. This will increase air circulation in the crown of the tree and prevent open wounds that invite disease.
Prune to remove branches that have a narrow crotch or are growing the wrong direction with a pruning saw or pruning clipper. This will increase air circulation and create an eye-appealing shape.
Prune the crown of the Japanese tree by trimming branches with a pruning clipper to form a desired shape.
