We have had a very dry late summer this year. Dry conditions can take a toll on both new and established trees. Once trees become stressed they are more susceptible to diseases and disorders. However, watering your trees into the autumn until the ground freezes will increase tree health and reduce the chance of winter damage. 
Trees thrive on less frequent, deep watering to maintain soil moisture at proper levels.
Follow these guidelines:
New trees (1-4 years old)
Established trees
