Answer: You're right, dogwoods can be temperamental, but when given the right growing conditions they develop into beautiful landscape trees. Since you've only recently planted your tree I think it is just adjusting to its new environment. This transplant stress will continue until the roots become well established. Lots of rain can keep the soil too saturated and the roots can suffocate. There's not much you can do about rainfall, but you can take care in watering - when it finally stops raining! - by deeply soaking the soil once each week throughout the growing season. It is early in the season so I think the tree will replace the dead leaves. By next spring it should flower and leaf out beautifully for you. Enjoy!
