Sounds like it may have been kept too wet or watered too often. If your soil is not well drained this is more likely the cause. Anyway you can either take a sample to your County Extension Office for diagnosis or try purchasing a fungicide and drenching it over the bed according to label instructions. This is a hit and miss approach since we don't know which fungus is causing the problem but it may work. The ingredients to look for when you go shopping are: benomyl or triadimefon (Bayleton) .
Thanks and please stop in again soon!
