I have a wisteria 15 years old.. no flowers have ever appeared. even though I have religiously pruned the whippy shoots etc in Aug and in Dec each year.
I have even had other trees cut down to make sure it was getting enough light. it is south facing.
I am now going to prune it very hard and shock it into life. if I lose it I lose it !! Any helpful advice
