Bizzy Lizzies dying quickly
Hi I'm new to this forum but I hope someone can help me. The past few years have been disastrous for my bizzy lizzies. I've spoken to other people who have the same problem. There was one year when it was hard to get of these plants and then they returned but they've never been the same since. The "newer versions" dont grow as big,they don't go to seed and even worse they die overnight in Aug/Sept. One minute they look great and the next the leaves and flowers have all dropped off leaving bare stems. In the past they would continue until the first frost. No one I know manages to keep their bizzies that long any more. I should add that all the plants have been bought from local nurseries. They are one of my favourites and I'm wondering if I should try growing my own to see if they are any better. Has anyone else experienced this problem?
