A large number of the problems experienced by your dogwood tree will likely be as result of poor soil conditions, inadequate moisture and watering, or  improper care.  Ensuring the proper growth conditions should be your first concern.

Dogwood borer Dogwood Borer
The Dogwood Borer is a pest which threatens not just dogwoods but also members of the hickory, elm, willow, oak chestnut and apple families among others. It is common in the United States west of the Rockies and in Canada. Damage is caused by insects in the larval or caterpillar stage burrowing beneath the bark of trees to eat healthy tissue. Moderate infestations slow growth while heavy or repeated infestations can kill trees by girdling and disrupting the flow of sap.

Dogwood anthracnose Dogwood Anthracnose
The lovely flowering dogwood, source of so much delight from its spring flowers to its autumn colors, has a lethal enemy - dogwood anthracnose. Caused by a fungus, Discula destructiva, dogwood anthracnose has devastated wild flowering dogwood populations in large areas of North America. The disease is relatively recent in origin, first noticed in 1978 with the fungus itself only identified in 1991.

Powdery Mildew
Powdery mildew is a common fungal disease that can appear on many types of trees and plants.  While it will not necessarily kill outright, the plant or tree will become more susceptible to other problems and its appearance and the amount of fruit it produces will become compromised.
