Q.My Wisteria Tree
I live in southern New Jersey. My wisteria was budding when we just had a couple of days of unseasonal cold weather. When I went out to look at it after the cold days the buds had turned brown. Will it still flower? Do I cut all the buds off?
I'm sorry your Wisteria got affected by the colder temperatures! It is very possible that it will not bloom this year. Here are two articles that may help you:
