Many wisteria can take more than 7-8 years before ever flowering. You can encourage flowering with fertilizers that are high in phosphate. You can root prune the wisteria. You should also prune the branches.





August: Shorten-back current season’s shoots to 30cm (12in). This allows more sun to get to the wood, encouraging flower-bud formation.





February: Shorten-back the summer-pruned shoots to within 2.5-5cm (1-2in) of older wood or two to three buds. It should be possible now to distinguish the plumper flower buds from the slimmer growth buds.





Long, whippy shoots that grew after the summer pruning should also be pruned. Cut these back to five or six buds from the main branch, making the cut just above a bud.
Reply:Probably too much nitrogen resulting in excessive growth at the expense of flowers.
