At times the height of a tree needs to be controlled (i.e. growing into power lines, obstructing a view, etc.) we do this by reducing the height down to the lateral branches that are at least 4% of the diameter of the parent limb that it is growing off of. This allows the lateral branch to resume the role as leader. By cutting back to the correct size lateral branch, "sprouting" is minimized from the cut. Many trees can be reduced in height and still retain and very natural look and shape.
