| My two Heritage David Austins that grow together got rust this year. Now, what should I spray them with or should I pull them out like this man in a NZ rose book I read from the Library suggested. What do you all do ? |

You would have to be kidding, pulling out Heritage roses!!
I'll have them!I dont know where you are and what your soils are so..
Actually you could use a strong dose of mancozeb, our area is called the blackspot and rust area of Victoria, so have vast experience of little wrens etc jumping from plant to plant, yes they can be spread by birds and secateurs not cleaned and even garden gloves. Also if you are near farm paddocks rust can come from spores. Make sure you spray the underside, some pull of the leaves but once sprayed the rust should die and the leaves can fall in time naturally. You may have to follow up but for only two plants should be no problem for you. If you are pruning and spraying now soak the ground with mancozeb and remove all cuttings and burn. Some use lime sulphur in other States, have found a reaction on heavy acid soils here, little microbes dont like it.

| Rust is not a fatal rose malady. Triforine is supposed to eradicate it, but I have no rust so have not needed to worry. Rust becomes active through overcrowding and poor air circulation amongst the plants. |

| Well,checked your page and you had me fooled living in the Virgin Islands, couldnt find the Victoria ones on a search lol, so assume by your love of camellias that you would be in southern area of victoria with acid soils. Your garden sounds wonderful I too love camellias azaleas and rhododendrums. Obviously roses. We also have box headging so share many plants. Did you get snow recently? |

Now Lozza,
I will disagree being a rust, expert lol! It can come on a single plant not overcrowded and us farmers can have huge sprays we can use, in the paddocks, fortunately ours dont have it, but neighbours do, we all go for underkill before overkill. We graze it out before it goes too far and hope for some hot sun! I totally agree it is not fatal for roses and I hope it never comes your way! For the amount of roses we have I would say only four were affected last year while away.

| Sorry to mislead you Lynne, I have had it,but in very small doses. Are you talking about the orange pustules under the leaves with yellow dots on top of the foliage? I thought the pasture or paddock rust was a different breed. |

| I had persistent rust on one rose bush (Perfume Perfection) and pruned it down to the ground. None of the new growth has any rust now. |

Rain keeps us inside my dear distinguished Lozza,
These are some of the things one of the sprays does if you try for roses, we do have lots of clover, have never really made a deal about how it looked, looking at some of the farm sites our appears similar to leaf rust.
Then looking at fungacide sites, they all look similar. As I do not profess to be a scientist, I will leave that up to them.
Beetroot, Cabbage, Canola, Carrots, Chickpeas, Clover, Faba beans, Field peas, Lucerne, Lupins, Medic, Mung beans, Navy beans, Onion, Peanuts, Honeydew melon, Peas, Potato, Radishes,roses, Soybeans, Sub clover, Sunflowers, Tomatoes, Pineapples, Cucumber, Vines, Pumpkins I must say though funguses are very interesting little creepies when you do research on them, but most love mushrooms!!! Rust can pop up anywhere, anytime, depending on certain seasons, so why cut out roses? The breeders would be very sad lol! Some roses are more prone to it than others though. I am sure we will hear from the others which ones. |

Only one rose in my collection has ever had rust - L. D Braithwaite (Austin). I just pull off a few of its leaves (put them in a plastic bag in the bin)as it normally has rust at the end of autumn. It has never spread to the other roses. I like this rose and so am happy to put up with it - but if it had it all year it would be shovel pruned

Thankyou everyone for your Info. I am going to do the spray and not the Pull! I wish I could remember the book, the guy was from NZ so maybe they just yank the roses out there! LOL
I am not in the Virgin Island , but its so cold in Melbourne that I wish I was!!! No, I did not get snow where I live (too close to the city). But I had a polar bear in the backyard!
Shall be buying the spray this weekend. Thanks everyone. |
