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!
