Canna Flower Buds Are Turning Black And Drying Before Opening

Question From: Mathews, Virginia, United States
Q: Hi Nancy, My cannas have vigorous green foliage but the flower buds are Turning black and drying up before they open. Any thoughts about this problem?? Please help!

A: My research indicates you have a disease known as canna bud rot. I could not find a remedy. I live in Michigan and cannas are grown as annuals here. I would contact the American Canna Society for assistance. Google search for contact. Best Nancy
