Hollyyhock Rust and Propane Burner. Anybody who grows hollyhocks knows just how disfiguring this fungus (Puccinia malvacearum) can be.
http://ukeep.notlong.com/ 27 June 2007 Pictures of a few of my hollyhocks with no rust (Puccinia malvacearum) present.
The area was flamed in the fall and I contribute the absence of rust to this practice. Over the last three years by this time in the season the hollyhocks were severely infected with rust. The flaming does not kill the plants. I have about 12 plants in the same area (not in bloom yet), and no rust is present on any them.
