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

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, Gaynor,
Looks like rust to me. Best thing to do is cut it back this autumn and destroy all the leaves - don't compost them because this can help spread the disease. In spring, you can apply a fungicide on new leaves to prevent rust from coming back.

My recently planted Hollyhocks are growing well, about 3ft high. Have just discovered bronze, light coppery flecks. I suspect rust. Looking closer is it magnesium deficiency? Can you please advise. Help very much appreciated. Thanks,
Gaynor.
Gaynor.
