Q.Vibernum Does Not Turn Red In Fall
We have 3 healthy looking vibernum shrubs planted 30 years ago. Since then they have grown into one huge healthy looking bush. They are in a sunny location.It was only a few years ago that they has begun to flower, though we don’t have many. They turns brown instead of red in the fall. What can we do to encoourage more flowering and, especially, the red color we love so much?
