Help! Wisteria not flowering

Hi! 

What am I doing wrong! We moved in a 3 years ago and the wisteria was nearly dead, hanging off the wall and not pruned. Since we have pruned it to 5 buds in autumn and 3 in winter. It has never flowered. All the buds become leaves. I have put some Q4 fertiliser down last week. What are the chances it will flower this year?

    Hi and welcome to the forum.
    This has some advice on growing wisteria and may hold the answer to the flowering problem. https://www.rhs.org.uk/plants/popular/wisteria/growing-guide

    Feeding it is definitely a good idea but the pruning system is a bit wrong.  The usual rule is to cut back to 7 buds/nodes in July and then 2 in February.    However, once they get to certain size that's way too much counting so with the two big ones we inherited here I now prune back and new long whippy growth which appears here form June to September and I don't count.  I just cut them back to a bud or node just within the main framework so we can walk past without being mugged and also so that doors and windows are not blocked.
     
    For the February prune I cut back any stem heading up behind gutters and trying to get into the roof tiles and then, when they've been cleared, I check the general shape and prune out any that looks unbalanced. 

    I suggest you go over yours again cutting off any dead stems that are left beyond a  bud - eg that one in the middle of your close-up and then leave it be till July apart form making sure it has plenty to drink in dry spells.   In July, cut any new long stems back to 7 buds, making a sloping cut just beyond the bud/node.   You can also train in those long whippy growths as they grow above the door and window.

    This is what ours looked like when I did them last month.   This one is not growing in a pot, despite appearances.

    I would also water copiously. Your wisteria is surrounded by paving and it takes a lot of moisture to produce flowers and leaves. I would pour two buckets of water slowly onto the root area at least twice a week from the end of March to mid September. More often in warm dry spells.

    Hi @katrinks    Its a little bit early for them to be flowering and it's still quite cold. The buds are there so you just have to wait.
