Hi, Gerri,
First thing to do is make sure you remove and destroy (not compost) any infected leaves. Have heard of two remedies that are supposed to work (but haven't tried myself - still worth a try, though!). The first is to spray with a milk/water solution - have heard 3oz of milk to one gallon of water but I'm sure more milk can be used. Other method is to top-dress soil undier the hollyhock with cornmeal. Finally, make sure when the plant dies down, all infected leaves are cleaned up and destroyed - the fungus can overwinter in the soil.

Hi Kathy,

Many thanks for your suggestions. I have been removing and disposing of the leaves as suggested but was unaware of the two solutions that you have offered - worth a try. I will let you know if either of them work.

Best wishes
Gerri
