Q: I bought a flowering Japanese Wisteria from a local nursery. I planted it in my backyard next to a pillar where we get plenty of sunlight and water. The soil is clay. I live in Seattle with rather damp weather throughout the year. Off late, the leaves of my Wisteria have turned yellow. My husband thinks that is what happens to the leaves in fall. Is this normal? Should I be worried?
Your husband is right on. Wisterias are deciduous shrubs that loose their leaves in fall. The leaves turn yellow from lack of chlorophyll. So not to worry. Best And Happy Yardening, Nancy.
