Why are my tree leaves yellowing or browning out?
This often happens as we approach fall. New plantings are very susceptible to this. I also see older trees do this, especially large-leaved trees, but all will do it.
The tree is pulling sap and energy to the root system and saving it for winter. It starts this process in early August. This, of course, is a stress on the tree.
The response by some trees is to relieve some of that stress by dropping leaves.
This stress also opens the tree up to many leaf diseases that are present all the time and just wait for the right circumstances to show themselves. I normally do not recommend spraying trees for disease this time of year. It’s often not very effective.
Best Management Practices should be observed through the fall and winter. Water it if gets dry, fertilizing, and spraying fungicides next spring at green up will most likely get your tree through this time period.
