Answer: The native dogwood is an understory tree in the woods and as a result does not usually do well in a hot sun location such as the one you are describing. It needs an evenly moist, organic, acid soil and prefers morning light or dappled light all day. It is also now subject to some serious disease problems. Instead, you might look into a Cornus kousa, an oriental dogwood; this plant tolerates sun better and is less prone to disease.
