My hollyhocks are too loaded with rust to save. I cut them down last year (in seed) and now I have infected baby plants everywhere. I just cut them down today & I'm putting 'everything killer' on the open wound of each stem (small paint brush) to kill them off, since I am too weak to dig them out.

I just learned of the rust resistant strain, but I'm afraid to put them into such a heavily rust infected area ("water resistant vs water proof!) afraid they too will become infected. I need a plant that will NOT get rust to put in that area? or is there a treatment that will kill it in the ground? I can treat my few rose bushes. But the hollyhocks were too much. I would like a plant(s) 3-5 ft high, long bloom in summer. Can I treat area? use 'resistant' in such infected area? Other ideas? One photo shows the hollyhocks which are In the far right back corner of my cutting garden. Second photo is an overall view of both my center garden areas. back cutting garden is 25x12 or so, smaller water garden is 12x8 or so, and besides the hollyhock issue they are both doing very well. Water garden is just about filled in - cottage style. & this year I'll be removing any remaining weed block in the larger cutting garden - time to let the plants spread (and buy a few more, I'm sure). photos are a few yrs old already. Any help very much appreciated. I have a total of 4 gardens, not even counting the area around the house. I'm loving my retirement gardening!

You don't need to be concerned about other plants except those in the mallow family getting hollyhock rust, if that helps. That includes (according to the RHS) Hibiscus, Lavatera, Malvastrum and Sidalcea. That's not to say that you can't get a different rust on other plants, there are thousands of different plant rusts, but rusts are generally specific to certain plants and it would not be from the hollyhocks. Not sure if that helps answer the question?
