I have a section on garden bed that I'm letting rest for awhile. I covered it with wood chips as ground cover and to hopefully prevent a lot of weed growth while it is not in use. A few days ago we had a large amount of rain and now there are patches of fungus growing all over that bed. I have searched the internet and I'm finding a lot of conflicting information. What is the best way to stop, kill, or remove the fungus? Since the bed is not in use can I just cover it with a tarp and let the heat kill if off? Will that just make it worse? Any advice is greatly appreciated!
