This is the first year that I planted Hollyhocks. I have been pleased with the progress of the plants, not expecting any blooms until next year. The good new is I have two blooms. The bad news is (and he reason I am writing) is that practically all the leaves, the top anf bottom, are infested with something. My husband thinks they are eggs of some parasite. Can anyone help? In the meantime I have sprayed with Dipel, Bacillus thuringiensis, hoping this may help.

    Check out Jerry Baker's site for homemade safe pest sprays.. Try dish soap and water also.

    Help answer this question...I agree with Patti. I would spray with Dawn & water mixed together. And check out Jerry Bakers site.

    The link below is for the UGA Extension Service. They probably offer free advice for problems like this. Call them.

    Thank you Patti and Cheryl. I will try that suggestion.

    I agree with the above suggestions. Seems to me my hollyhocks always had "the crud" under their leaves - which didn't stop them from blooming, spreading - in fact, they thrived!

      @Andi hurtig Thanks, Andi. Do you know what the ratio of water to dish soap should be?

      @Andi hurtig I copied a page but it didn't paste very clear! About 2T/gallon...not more than that or you'll burn your'll have to reapply, but this works on aphids, whitefly, and assorted other bugs!

    Dipel is a caterpillar control. Your hollyhocks have rust, which is a fungal disease that they are extremely susceptible to. You need to remove the affected leaves and use a fungicide. If you want to go an organic route, try one with neem oil. It is very important that you completely cut down your hollyhocks at the end of the season and dispose of all the foliage. Do not compost it.

      @Liliana Wells You might try a different spot, and a different source for seeds. Look for those that are known for being rust-resistant, like the Spring Celebrities series.

    @Douglas Hunt This is good to know - my daughter found one growing out from under the Latice work near her Porch - First year in bloom.

    Oh, Carol S...I love yellow holly hocks. I had hocks all along the front of my house and they looked awesome. Then, I dont know what happened, but over the course of a few years, I am down to one! I dont get it, they used to self sow. *Blatent hint* (I would be most happy to send postage if I could get some seeds!)

    I had the same thing happen to mine.

  • Julie J Julie J on Jul 28, 2014
    Happened to me too. My hollyhock was huge and beautiful, loaded with blooms. Then came the rust and it completely died. I planted a russian sage in it's place and it is fine.

    • Liliana Wells Liliana Wells on Jul 29, 2014
      @Julie J Glad to hear I can plant something else in that place. I have been tearing my hair out; then I read Hometalk and I feel better. Thanks.

  • Julie J Julie J on Jul 28, 2014
    Here's what they looked like. A moment of silence, please. Sniff, sniff.

    @Liliana, I've had similar issues with my clematis which is close to this hollyhock. I don't think it's related but sure is frustrating.
