Default Hollyhocks

Please can someone advise on the cause and cure of masses of yellow

spots -
merging into yellow areas - on the leaves of hollyhocks.


It's a fungus infection known as Rust. It's quite common and has a
devastating effect on Hollyhocks. Which is why they aren't anywhere so
common as they used to be when I was a lad.
Cut off and burn/dispose of any leaves infected, don't leave any plant
debris on the ground now or over winter. Spray regularly with a fungicide as
a preventative.

Thank's for reminding me, I'll do mine tomorrow. :-)
