My garden flox started showing all these white spots on its leaves. It almost looks like mold. Does anyone know how to treat it?

    It’s just powdery mildew. It affects phlox pretty commonly. Remove the leaves affected if you don’t have anything to use. You can use a copper fungicide on it but it’s mostly from high humidity and lack of airflow and if that’s not changed, it’ll return.
