Wisteria not flowering why?



  • Can anyone help with this wisteria problem? I have lived in this house for 26 years and have a wisteria growing on a south east wall, It looked old when we moved in and gave some flowers. I prune it every year in the prescribed manner and it produces vigorous growth. About 22 years ago we built an extension and trained the wisteria across the new wall, now we get flowers on the new (22 year old) section but the other 60% of the vine doesn't produce a single flower - despite vigorous growth all over. I was thinking maybe of cutting out the barren majority of the plant an training growth from the new section back to the original area.

  • We had ours for about 8/9 years before it flowered but it was well worth persevering with as it was fantastic then, sadly we lost it when a wall collapsed on itimage mind you we had it for about 20 years.
