Q.Black Dahlia Leaves

Zone YO42 2TH | Anonymous added on September 27, 2021 | Answered

My Dahlias this year have performed well and I have been pleased with them however there have been a few problems that I have not encountered before. Can you help me with the following issues: Some of my Dahlias seem to have suffered from dying leaves throughout the season even though the plants themselves have performed well with many good sized flowers repeating on a regular basis( see photo) Also a needed to remove one plant as it went from very healthy flowering well to a very unhealthy state almost overnight. The second photo just shows a Dahlia that has been flowering well but now seems distressed and has stopped flowering. Can You help with these problems please.
