Answer: I think I'd try again in the fall. With the cooler weather your new trees won't suffer quite so much transplant shock and should have several months to establish themselves before the hot and humid weather arrives. Water stress can cause the symptoms you describe, as can fungal diseases and aphid attacks. Inspect the curling leaves for pests, or a white fungal coating. If you find neither, water stress is probably the cause of the problems with your dogwoods. Wish I had more suggestions to offer!
