I have (had), wisteria I bought 3 years ago. It had white blossoms the second year and was about 20 feet. Appeared healthy throughout the winter, and this spring had many more blossoms. As I awaited for them to open they shriveled up and not a single leaf has appeared? what in the world could have happened. It recieved plenty of water. My husband applied a moss killer at some point, I am not sure when, but this spring about the time of blossoms dying he fertilized the lawn. Any Ideas as to what happened? and should I try planting another one in the same spot?
