    HollyHock infection thingy??

    Hi Guys,
    Can anyone shed some light on these yellow "Spots"

    .... and is it possible to post a thumbnail of the picture that when you click on it takes you to the actual picture?

    Yes it is hollyhock rust. They are very prone to it. You could pick off the infected leaves but it will probably reappear. Best to treat hollyhocks as short lived perennials and replace them every few years. Easy to raise from seed. Sow some now and you'll have some to flower for next year.

      If you don't mind chemicals, a systemic fungicide like Tumbleblight will stop it appearing on the new leaves ... for a few weeks anyway.

        I've given up on hollyhocks because of the rust.

          I find that single hollyhocks are less susceptible than the double ones.

            Thanks Wendy, I've already done some from the seed I collected last year

              Thanks for the advice

              I noticed have a hollyhock with Rust too .
              I'm unsure best course of action
              Guess just remove affected leaves and hope it recovers sufficiently

              Bar that it's growing real well

              I do have some friends from seed last year

                Me too. I've noticed that where hollyhocks seed themselves into cracks in paving/walls/gravelly areas, they seldom seem to be stricken with rust, which makes me wonder if growing them mean, in very poor soil, may be the answer. In my ground they just grow too lush, then succumb to rust. One of my favourite flowers, too

                Endless wonder.
