Hey guys i've had my Wisteria for for over 5 years and in that time it hasn't once. I just don't understand what is wrong. Every spring the leaves grow and thats it.

    Is it a named variety ? Do you prune it twice a year ? how much sunlight

    I've never pruned it really and it gets sun later in the day

    Is it a named variety ? Named variety are grafted onto a root stock which flower much younger than a seed grown plant , can you see a graft if you are unsure .  
  • I found mine flowered more profusely when I started to follow the twice yearly pruning schedule and fed it in autumn with potassium.  Cut all new growth to 6 buds in August and again to 2-3 buds on Feb.  When you see the curved fat buds you know there’s flowers coming.  I’m trying to train two as trees right now.

    I'm a bit concerned about the sun 'later in the day'. Roughly how much sun are we talking  about? They do like lots of light and heat. It  looks a bit small for five years, too. Is it sheltered from cold wind late winter? Do you see flower buds  form at all?

    If you google "RHS+pruning wisteria" you will find a guide to pruning your plant every July and January/February in order to encourage it to produce flowering buds rather than foliage.  You certainly don't want to be leaving all those soft, whippy stems I can see trailing up the shed.

    They do like a lot of sun but I've seen very successful wisterias on tall, west facing walls that get no sun till early afternoon.   It will probably help to feed it with a a rsoe or tomato fertiliser as these encourage flowers to form.

    Some wisterias do take 10 or 12 years to get to flowering maturity so patience is in order.   Well-trained and pruned they are beautiful even without flowers.
