Dogwood trees can experience transplant shock when planted as a bare root tree and the main reason we only offer our trees as potted trees. Potted Dogwood trees transplant extremely well and can be planted year round. Dogwood trees prefer afternoon and evening shade, especially in southern states. Dogwood trees flower in early spring with white, pink or red flowers. Dogwood and Redbud trees mark the beginning of spring because of thier early flowering time.
