Hollyhock Double Red with Rust
Wednesday, 02 May 12 Storms 29°C / 84°F
Hollyhock has what look like eggs on some of the leaves. Can someone ID the dots and what to do about them?
I did some research and discovered it to be a rust defect that is common to Hollyhocks: http://learningstore.uwex.edu/assets/pdfs/A2613.PDF
Is there a way to prevent the problem from occurring?
