Pruning after storms

The explosive cracking sounds of trees crashing to the ground are sickening to the stomach. With the damaging storms that have affected the area lately, trees will require special care and can make a full recovery.

Remove debris, then assess the damage

The first step in caring for damaged trees is to remove all debris. This is mainly a safety factor, but also enables you to completely assess the extent of the damage.

Can the tree be saved?

Next, determine whether the tree can be saved. Most trees will be salvageable and will need time to recover. If there is heavy splitting of the bark and the cambium, growth layer is exposed, or the main trunk is split, the tree will probably not survive and should be removed.

Also, if there are so many broken limbs that the form of the tree is destroyed, replacement may be the best option.  

Once it has been determined that the tree can be saved then pruning begins. Broken branches should be cut back to the next larger branch or back to the trunk. Never leave a stub when making a pruning cut. Stubs lead to rot and decay, and slow the healing process. 

When cutting back to the next larger crotch or branch angle, do not cut flush with the branch. Instead make the cut in the area referred to as the branch collar. The collar is a transition area between the branch and the trunk. Cutting flush with the branch or trunk leaves a larger wound, which takes longer to heal. The collar area is raised with bark tissue, much like the crease on your hand where your thumb joins the other fingers.

Larger limbs should be taken off in stages. Cutting a large branch at once often leads to a strip of bark being ripped from the tree increasing the amount of damage. The following steps to removing large branches are:

1. First cut about 15 inches from the trunk or next larger branch. Start from the bottom and cut about one third of the way up through the branch.

2. The second cut should be made from the top down, a few inches out from the first under cut. The branch will break away at the first cut as you make the second cut.

3. Lastly, cut the remaining branch at the collar, which can be supported to prevent the bark stripping.

Avoid “door knockers.” Hire a local reputable tree company

Large trees are best handled by a reputable tree care service. When selecting a firm always ask for a certified arborist and never pay in advance. Quality companies will bill or collect after the work is completed.

Topping is not a recommended practice of repairing storm damage. Topping weakens trees and makes them more susceptible to disease. If the damage is this severe then the tree should be removed. Also, no wound dressings are needed.
