Training and Pruning Deciduous Plants Correct training and pruning during establishment is critical if one is going to have a functional and attractive hedge. Immediately after planting, cut back deciduous plants to 6 to 8 inches above the soil line. This is done to develop branching near the soil line. While a variety of hedge shapes or forms are possible, one must have the base wider than the top. This allows the lower portion of the hedge to receive light.
Inadequate light reduces photosynthesis, and leads to death of the basal branches.
Basic Pruning Cuts Proper cutting can help develop the desired form and density. Every time the branches grow 12 inches, cut new growth back to 6 inches. Prune to an outside facing bud. Continue with this method until the hedge reaches the desired height. This is a slow process and can take five to six years, but a properly trained hedge is a striking addition to a landscape.
