    If you had a cold spell or a frost, they may have become damaged in the cold. Flowers are much more cold sensitive than the rest of the plant and will be damaged when the rest of the plant is fine.

    If you have not had cold, it could be thrips. They attack the base of the flower buds and cause the buds to drop off before they are formed. This article will help if you suspect them:

    It will not harm the plant to either remove the pods or leave them on the plant.

    Lack of color is normally caused by poor soil nutrition. Have your soil tested and amend it accordingly.

    Have you had a cold snap lately? The buds that withered, may have done so if they were touched by frost. Flowers are for more susceptible to cold damage than the rest of the plant. The ones that remained undamaged may have had some protection from frost from a near by wall or structure that gave off enough heat to keep the frost from touching the flowers.

    It may also be thrips. If you suspect thrips, this article will help:

    It may help cool the bars, but it could encourage fungus to develop on the plant. On the other hand, with it being so hot, the water could evaporate before the fungus had a chance to settle in.

    I would say that it is worth trying. Wisteria are pretty hardy, so if a fungus were to develop, in most cases the worst it would do is make the plant look a bit unsightly until the fungus was treated.

    Did you have a late frost in your area? If so, it likely killed the blooms.
