Two years ago I brought some Hollyhock that flowered beautifully and grew to their maximum height. The following year rust decimated them, so in the spring I got rid of the infected plants. This year its back and has attacked two of my four plants I grew from seed. I thought I'd got rid of the infected leaves but today I had to trim more off and a couple of flower buds.
It feels like a loosing battle and I'm wondering if anyone has tips? Do the fungal spores rest in the ground or something?
