Talkback: Hollyhock rust
in Talkback
My hollyhocks have had rust for 3 years now. I've always put it doiwn to the same rust as my apple tree and hawthorn hedge suffer with.Obviously not! I pulled all the infected leaves from the hollyhocks and burnt them. As soon as I saw the leaves starting with rust I removed the the infected ones and sprayed each p[lant thoroughly with a specific fungus killer.
Even the self seeded youngsters have the rust...so have been sprayed as well... and all will be sprayed regularly.
Fingers crossed!

No -only using a chemical spray will control rust-you will need to dispose of them after flowering and the spores can remain in the soil-there are rust resistant varieties available -check those out
