October glory maple leaves are wilting and brown :(
First time home owner here, and I have a October Glory Maple that was planted in Sept-Oct of last year. I live in Oklahoma and this spring it has been raining like spring weather should. I went away for the weekend, and it was a hot weekend, so the tree didn't get watered. I noticed in the last week the leaves have drooped and now have a burnt chrisp look to them. I water twice a week for 20 minutes at a time, soil below is moist, and I have mulch to help. Please help me!!!
