Why is my redbud tree wilting?
A. It’s possible your redbud tree has verticillium wilt, a disease caused by a common soilborne fungus. The fungus usually enters through a plant’s roots and produces toxins that clog its tissues and make it hard for leaves to get enough water so they yellow and wilt. These plants need 1 inch of water a week.
How do you treat Redbud verticillium wilt?

What does verticillium wilt look like on a redbud tree?
