wisteria buds look very dried out and no signs of opening
My Wisteria sinensis has lots of buds but they all look very dried out. Last year lots of leaves but no flowers, and was told I was watering too much. So last summer I watered during dry spells and gave it some tomorite. Made one seed pod, which also looked very dry and shrivelled (previous year it had been very full). Bought plant well established and flowering. Not sure if buds will plump up now or just dry out and fall off. Scratched stem and green underneath so still alive!

There are several things that can cause this issue.
It could be thrips. They attack the blossoms. This article will help if you think that it may be thrips:
It could also have been a frost. Was there a frost in your area after the buds were on the plant? The flowers are much more vulnerable to frost than the rest of the plant and can die if exposed to it.
It could have been underwatering, but you would need to be in drought conditions if it were this.
