Do I need to treat the soil around the plant? If so, how often should I spray?
Clearys Spectro 90 WDG is labeled for shothole. It is not labeled for homeowner use. We recommend that you treat the Otto Laurels for Coryneum blight (shot hole disease) with Bonide Liquid Copper Fungicide Concentrate. Bonide Liquid Copper Fungicide Concentrate should be treated around the area as well. The residual of the product will only adhere to the areas it was applied to and dried on. You would spray all plant parts thoroughly (top and bottom of leaves), and unless otherwise directed in the crop table, repeat every 7 to 10 days.
