The wysteria was doing really well and full of buds ready for flowering then over the past 2 weeks a huge amount have died whist on some branches others are flowering. Can you advise what the problem is
Cold! Frost or a blast of cold wind will damage wisteria buds and flowers and heavy winds and rain won't help either. Make sure the plant is not going thirsty and that you give it a good feed of something like seaweed, rose or tomato fertiliser to help it with general health and flower production.
