Question: My wisteria blooms in the summer and fall. Is it abnormal? Will it affect the next spring’s flowering?
Answer: Anytime a wisteria comes out of a prolonged dormant period, its natural tendency will be to set buds and then flower. That, of course, happens as it makes ready for spring blooms, but it also can happen to a lesser degree after the summer. Pears and apples will often do the same thing.
