    @john558 At a guess your Hibiscus syriacus is not flowering, because you pruned it. If I remember right the flowers form on older wood rather than young shoots. I've had a couple over the years and they have never needed pruning.
    Your foliage is a very light colour, but that could be down to light conditions when photo was taken, my foliage is generally dark green.
    Not enough sun can result in no flowers and that is why I need to move mine when I have a vacant spot in a sunny area as it is being shaded out where it is at the moment.

      Hi, the pic of the flower was from last year, there are a few flower buds this year, but I need a stepladder to see them!!!

      It's in the ground Pete

      I really want the bush around 3ft high, so is it prune and not feed next year:scratch:

      I'm going to disagree with Nigel on this.
      They flower on new wood after mid summer, so you can winter prune, but really hard pruning does affect flowering, at least that is what I find.

      I've got about a dozen or more planted in the garden or on the allotment, most are just seed grown with only a couple named varieties.

      The foliage will be yellow now as its getting ready to fall.
      But I have noticed some of mine are a bit yellow in summer, I think an iron feed maybe the way to sort that out, but never bothered.

      I think you can feed too much, never feed mine, and never water them.

        Have to agree, pete. The theory goes that you prune in early spring. If I do that, the shrubs struggle to regain their strength. Put on lots of wispy shoots, but don't flower as well. I leave them alone now, apart from dead-heading the seed pods. @john558....they're quite big shrubs normally and I really don't think yours is going to be happy being chopped down to 3' every year! Older plants don't move well, so your best bet is to let seed pods form and sow new shrubs. You should get one or more the same colour, then you could plant it somewhere where it can reach it's natural height. Then it will flower well.
