Trees - Pruning

Tree wounds from pruning heal faster in the summer.

Trees are pruned to remove branches that are too low or obstructing traffic, to give the tree a better shape and appearance, to remove dead, diseased or broken limbs, and to raise the shade level so that grass or flowers may be grown.

Two very important elements of tree care are pruning and wound treatment. These are the most often overlooked fundamentals of tree care. Trees are pruned to remove branches that are too low or obstructing traffic, to give the tree a better shape and appearance, to remove dead, diseased or broken limbs, and to raise the shade level so that grass or flowers may be grown.

Some prefer summer…

Pruning can be undertaken at any time. Some gardeners and tree experts prefer summer pruning because it is easier to spot dead limbs plus the wounds heal faster during the growing season.

Pruning tools…

The job of pruning can be done more safely and correctly if the proper tools are used. Generally, a tree saw is most preferred; it can be mounted on a pole or used as a hand saw. Bow saws or carpenter saws can also be used. The prime objective is to remove the limb with a minimum of injury to the tree and to keep insects and diseases out of the pruning wound.

Larger limbs…

Limbs larger than one inch require a special technique because larger limbs will fall before the
cut is complete. Many times this will tear the tissues or splinter. To prevent this requires three separate cuts, with the first one 6 - 12 inches from the trunk on the bottom side of the limb, cutting about halfway through the limb. Make the second cut on the top a few inches further out than the first cut. The weight of the limb will cause it to break back to the first cut. The third cut should be cut close to the trunk or a major limb.

Wound treatment…

Large wounds and wounds on Silver and Norway Maple may not heal or callous rapidly and completely. Healing can be quicker if the wounds are pointed. This means rather than a round, oval wound the wound is made to be a long elliptic by using a knife or chisel to taper the wound at the top and at the bottom. Always make cuts as smooth as possible. Large wounds may require several seasons to heal.

Remember pruning is undertaken to repair damage to a tree or to make them safer and more attractive in form and shape.
