I just planted an autumn brilliance serviceberry on 6/27 (6.5 gallon/multi stem). It has been hot the last two days. The nursery suggested watering once a week at a rate of 1 gallon per minute for 15 minutes. I watered it when I planted it and 7 days later I did the same. The tree appears to need water. The leaves are rolling and have a silver tint but the ground feels moist. Some leaves are also showing a red/yellow line that starts and stops at the stem and has a similar shape as the leaf. Inside of the line the leaf color is a rich green. Outside of the line the leaf appears to be dying as if the tree is in stress and it’s life blood is receding. I had an autumn maple in the same place previously and it died. I was told that it was due to lack of water or lack of iron. Prior to the trees being planted, this same area was overgrown by a very healthy juniper bush which was removed 8 years ago. Any advice would be greatly appreciated.
