    Customer's saying they have a fungus present in the lying area just underneath a Magnolia Tree. An arborist tells them it may be from over watering the tree itself(or something to that sort). They're wanting to know if that troubled area underneath the tree can be treated with a fungicide and/or will it affect/harm the Magnolia itself?

    its probabally from being in the shade and being overwatered. Check the label on
    a good systemic fungicide. Armada maybe.

    Is it sooty mold, which is frass from aphids or scale?

    I was just looking at the site below yesterday. I'd say magnolia scale without seeing it. I had a customer who had it on a saucer mag. and suggested they use a light weight summer oil. If they are heavily infested, it may take two apps, IMO

    is this black sooty mold under the tree or is the grass thinning or yellowing out?
