Structural Pruning on a Walnut
Structural pruning refers to a pruning approach that involves cutting back competing lateral branches to favor a strong leader. In this approach, a tree will have a strong leader and competing side (lateral) branches are kept narrower than half the diameter of the trunk. Co-dominant branches are not allowed to grow. This approach can be practiced on trees of all ages, but in this case one cut was made to improve the structure of an unpruned ,mature walnut tree.
