Tuesday at Two (July 16th) and Hollyhock Rust

Beautiful weather again. If we could just have a good rain one night it would be perfect!

Down in the rockery a hollyhock has bloomed, and is looking fairly healthy still.

However, the dreaded rust is already attacking its leaves. I shall have to remove them and dispose of them, as I would hate it to spread to the nearby Hibiscus. Do you have any plants affected by rust? Does anyone have a cure for it? I’d love to hear your suggestions!

The RHS website www.rhs.org.uk has some useful tips on dealing withhollyhock rust here.

  1. I hope you get a nice soaking gentle rain soon! Your hollyhocks are lovely (such a beautiful colour!) – they’re one of my favourite plants, although I don’t have the space to grow them. Rust is such an issue with them, it’s too bad.

    • Thanks Sheryl. No sign of rain yet! This is the only one that has prevailed – originally I had a lot of pale yellow ones – I’m so glad this one is pink!

  2. Your hollyhock is beautiful, I’ve never tried to grow them because of the rust, maybe I should have a go, I have somewhere they would look rather nice. I think some people grow them as annuals because of the rust, I haven’t heard of any organic remedy, sorry.

    • This one has come up the last four or five years, but all the others I originally sowed have long disappeared. Some people are fortunate and don’t get rust, so give it a go. You may be lucky!

  3. pretty flowrs, my hollyhocks get these yellow lines every year, but it doesn’t stop the flowers from blooming beautifully, in fact the kind I have is resistant to it, it still gets it it just doesn’t affect the plants overall beauty and health, It seems to happen only when they are blooming and I am guessing the stress of blooming is taking alot of nutrients from the leaves to make and I am thinking if I increase the sulfer in the soil that would help, sulfer, magnesium and iron from what i can tell are what is needed for plants to produce reds, and purples and so maybe some of these nutrients rae taken from the leaves leaving them vunerable to the virus. not sure not a botanist or anything, sulfer and other minerals seem to be solely lacking in the usa because of the reduced sulfer and minerals in the waste products of water processing, utility companies burning less sulfer rich coal and scrubbers reduces the nutrients in the soil, of course not wanting to breath the stuff notwithstanding.

  4. They always suffer from rust, I don’t think it usually spreads easily to other things. I hope you have some rain, I think we won’t have any more now for a while but I could be wrong.

    • There are some on sale claiming to be “rust-free”, but I don’t see how it’s possible… (like my zucchini plants claiming to be mildew resistant. 😉 )

  5. I love hollyhocks and so do the bees. They withstand the heat and dry so well I could not imagine doing without them. The bottom leaves do seem to suffer from rust as they age but it never seems to go onto anything else so I don’t worry about it.

    • Mine is a hardy shrub: Hibiscus syriacus. It’s survived down to -22°C (-7°F) and would probably survive even colder winters too. 😀

      • Wow I doubt my gem from Lowes Department store would do that well it was on it’s last leg and root bound when I paid so much for it. I will keep it warm inside this winter and try her in a sunny space next spring and try a bucket over her to protect from icy winds 🙂

  6. I haven’t grown hollyhocks for years, but the RHS says that rust is worse in wet summers – so maybe you should rethink that wish for rain! Such lovely flowers though, they must be worth putting up with a bit of rust for.

  7. Is it climate? My mother grows hollyhocks every spring and I’ve never noticed rust. We get so much heat and very little rain. She does keep them well watered, but it is a bit surprising to me that they do so well in the heat. Naturally, the heat we’re talking about is spring heat, not summer. I hope someone comes up with a suggestion, because they are really such a beautiful focal point in the garden!

    • I think the virus that causes rust likes humidity, which would explain the success in your climate. Lovely that your mother can enjoy them in the spring! 😀

  8. I hope you get some rain. We got some yesterday, which is very unusual for us in July! Your hollyhocks are beautiful. I love that shade of red. I’ve never tried growing hollyhocks, so I can be of no help, but you would think that someone would have come up with a rust-resistant variety by now.

    • There are apparently rust-resistant ones, but I’m skeptical! I always buy “mildew-resistant” zucchini seeds, and they ALWAYS get powdery mildew later in the year! Still, the flowers aren’t affected and they draw the eye away from any unattractive foliage. 😀 (No rain forecast for the next 10 days… 😦 )

  9. Rust is putting me off growing them too although they’re beautiful…until rust hits them. Hygiene is extremely important, removing leaves as you notice infection, never put them on the compost, cut down after flowering, mulch in the autumn and it’s probably best to remove and replace them after flowering. Also you shouldn’t use seed of affected plants. Do you have deer visiting?

  10. Gorgeous hollyhocks, shame about the rust 😦 I don’t know of a cure as I’ve not much experience growing these. I’ve noticed quite a few growing out here in France on holiday. They are lovely.
