I live in Alabama and have had this pink dogwood for several years now that has only bloomed once. It seems very healthy, why will it not bloom? I do not feed the tree. It is planted amoung pines and gets about have shade and half full sun. The tree is about 6 years old and the foliage is very nice and dark red as the season continues. The average cold temp. is around 35 to 40 degrees and the summers can get in the 90's often. I also have a white dogwood tree that has always bloomed.
