Oak Tree Losing Leaves #810406
Asked September 12, 2022, 10:45 AM EDT
I have a red oak tree that is over 15 years old and about 25 ft. high. The new leaves at the tip of the branches are turning brown and dropping. I think it's due to the drought and dry spring. I've been deep root watering it about once a week. Should I water more? If so, how often. Will it recover this winter. Should I water it this winter during warmer weather?
I'm sending photos.
