Wisteria Bloomed All Summer!?
I have a friend who has a wisteria that she grew from seed. She got the seed from Arkansas and it has grown wonderful in our Wisconsin climate. It is probably about 15 years old and she had never gotten a bloom on it until this year because she was pruning it wrong. It finally bloomed this year and has not stopped blooming and it is October! She says that every week she trims back the vines that grow outside the trellis. Could this regular cutting back promote bud formation? Any ideas???
