Thank you for your response Sandi. The are on a steep incline and get good drainage as does the bed directly next to them does, which also contains lambs ear. we have about 40 lambs ear in each bed (they are our main landscape border in the front of our house)- they are west facing beds so they get lots of sun to dry them out. One bed has this "soil disease", the other apparently does not. We have spent hundreds of dollars replacing lambs ear in the past two summers, not realizing that we had this fungus. But the fungus doesn't seem to go away. The beds were prepped by a professional 3 years ago when we built our house. We continually work them, mulch them, etc. Isn't there something we can add to this bed to kill this fungus so we can save the remaining plants? I read about some fungus in the soil called 'phytoplorus-' something like that. Is that maybe what we have? Someone told me cornmeal would help but how do I apply it?
