Hello everyone, I have a few questions about a few gerbera daisies in a bed that gets full sun. They are wilting almost as if they are dieing. I water this bed often and my other plants in this bed are doing well. What could be causing my gerbera's to be wilting? I was reading that it could be crown rot if I did not plant it correctly, but I think I planted them right. Does anyone have any suggestions on what I might try?

Thanks.
