Q: OK, I am going to remove my old, infested mulch. But, what do I do with it?
A: The best thing to do is probably bag it in a biodegradable bag and take it to a landfill. At least the mulch is organic and will rot away. Make sure you don’t put the infested mulch somewhere where you could be held responsible for someone else’s artillery fungus problem. This is out of my field, but it has been suggested that the infested mulch could be put in a yard waste-composting facility. But you really need to ask this question to a “compost expert.”
