Q.Wisteria Color of Blossoms
Have just moved into house with a garden. There’s a beautiful and well-established wisteria vine, espaliered against a wooden wall. However, the blossoms are not the usual purple or lavender. Instead, they are a dirty white color. Can I change this color by adding something to the soil, as can be done with hydrangea that is pink rather than deep blue?

Unfortunately, there is no way to change the color of the wisteria. Lack of color is normally caused by poor soil nutrition. Have your soil tested and amend it accordingly.
