    For the past 2 years I have had a problem with a serious fungus on my French Hollyhock. See the attached pictures. I have tried various fungus sprays but nothing seems to help. The fungus only seems to attack my hollyhocks but does not affect the hydrangea plants that are next to it. Occasionally I will see the same fungus on my grape leaves but I will remove the leaf(s) and the problem goes away. The fungus appears to spread from the bottom of the plant (1 or more) leafs at a time until I find it all over the plant and usually have to destroy the entire plant. Does anyone know what this fungus is and how do I get rid of it. Thanks.
