Hi, I am new and would appreciate some help regarding my Live Oak. Two days ago it looked healthy and beautiful.... Today it has brown leaves, and very sick.... What do I need to look for, and what do I need to do to help my tree recover? Not all leaves are brown: I would say about 50% of this tree is affected. Please help. Thank you ColleenGodwin
Mineral salts in irrigation water? Salt-laden coastal winds? What has happened in the planting site recently?
Lots rain. We water from a well. Fertilized the lawn last week: Scott's turf builder. This tree was planted 5 years ago.
I almost included herbicide damage in my list of questions. Timing would certainly suggest that it got burned by something in the fertilizer. Maybe you put on too much.
