I need to treat this island in my yard that contains A crêpe myrtle tree, and several azaleas that have been affected by disease. I need some advice on how to treat the area to prevent spread. I have read that an aphid or an insect might be the initial problem that has been led to the spores of black mold, attaching, and around in circles I have read. I’m not sure which or in what order I should Treat this area I have Sevin, which is a systemic insect killer. I have a fungicide and I have neem oil at my disposal. I would love some guidance as to where I should begin or how I can contain this area and treat please help if you can.
