Allison's Pine Tree

Paul determines a number of problems with the pine that he will try to address in order to save the tree:

Problem 2: Flush pruning cuts have left open wounds that allow a lot of tree sap to flow.

Problem 3: Dead branches can attract insects and disease.

When limbing up a tree, be sure to leave an inch or so of wood to retain the branch collar so the pruning wound heals properly. How high you limb up depends on the length of your pole pruner. Paul and Allison take the opportunity to also tidy up the red oak growing next to the pine, where the two trees have been crossing branches.

After drilling the holes, Paul helps Allison fill them with a composted product that contains beneficial fungus known as mycorrhizae. It dramatically increases the roots' ability to take up nutrients and fight disease. In return, the roots feed the fungus. This symbiotic relationship results in improved plant growth, prolonged life, less need for fertilizers and, hopefully, a much healthier tree. It’s a natural way of promoting the health and vigor of the tree, but it takes a while so don’t expect overnight results.

One more thing is crucial to a healthy tree: deep, thorough watering. Try for 30 minutes, and watch for runoff so you don’t waste water. A good watering should get way down into the subsoil. It will help the tree, and also help get the beneficial fungi growing actively.
