    what about Sulphur Dust? has anyone tired this before?

    Controls and prevents black spot, rust, leaf spot and powdery mildew on roses. Multipurpose - can be used on fruits, flowers, vegetables, flowering plants and ornamentals

    Just sprinkle on plants

    Well, that's an interesting tactic to fight disease - just cut them out.

    You won't be growing roses for much longer.

    Maybe see if you can get it shipped from one of the Bayer sites. It is not at all expensive when you only use 1 1/2 tablespoons per gallon. Sulfur is a good idea too, but don't think it will last as long with rain. Anyway the healthy leaves on your roses look like it is pushing out some new leaves. Remove the bs leaves and give it a dose of spray or sulfur. I do mine every week for 3 weeks and then watch to see if it reoccurs. Remember once you have that much bs...those leaves will only get worse and are pretty much gone, when you see it. After spraying the leaves seem to get worse, but never fear they will clean up well. Good Luck!

    Good grief! So they get spots now and then, big deal. Are the blooms any less beautiful or fragrant. I think not! Give up trying to be a perfectionist control freak and learn to live with some spots. You'll enjoy your roses a lot more!

    BTW, the orange spots are probably rust which is another fungal disease.

    Maybe rather than roses, you should look in to native plants for your area.

    Roses seem to come with good and bad, guess you have to balance your vision with your areas reality. Magazine perfect might not be a reality unless you bend your vision.

    Canada seems to allow less chemical fixes, it seems to me-as a newbie, that there are pretty much two camps. Those that love Bayer products and those that wouldn't touch them. You don't have that option, you can't buy them.

    Frankly, a bit of rust, a few slug holes and a couple of black spots would not cause me to grab the shovel and dig up an otherwise happy blooming rose. (it will cause me to come here and ask for help on earth friendly rust products though...)

    Any list that includes 'Double Delight' on a list of roses deemed to be "easier to grow and more disease resistant" cannot be taken too seriously, IMO. I mean, come on....'Double Delight'?? (Neither 'Fragrant Cloud' nor 'Blue Moon' are any better, in my experience)

  • harmonyp

    Am I just too lax? This year is my first year for blackspot as well as rust. I look at what you are cutting and think - hey that's not bad - if it were mine I'd just leave it as is - I'm not cutting or spraying mine. They seem to be working it out on their own just fine... and I know mother nature has been doing this a long longer than I have...

  • henry_kuska

    Paul, your growing conditions and strains of fungus can be very different than found in pesticide free Toronto. i.e. your use of chemical sprays can be the cause of you having diseased roses that "could be" relatively disease free if grown in a "natural" environment.

    "Double Delight rose an excellent flowerbed plant that also looks lovely planted in a mixed border.

    It has good disease resistance, except for cool damp climates, where it is susceptible to powdery mildew.

    Be prepared to apply preventative sprays if this problem is common in your garden.

    It does beautifully everywhere else."

    That really doesn't look like BS to me, I'm no expert on the diseases but do have lots of experience w/BS here in humid central Fla., I have lots of BS in my no-spray garden but would never SP a rose for the little bit of whatever the problem is, that you show in your pics... I have several Double Delight and they get lots of BS, but I plant something smaller in front of them so the bare-knees are not visible, Blue Salvia does a good job and works well w/DD.... one cannot be a 'perfectionist' when growing roses, it just doesn't happen! sally

    Hrose, as near as I can make out, most, maybe all, of your photos are of leaves infected with rose cercospora rather than rose blackspot. Not that cercospora is more attractive but in my zone 5 garden, cercospora tends to infect a few roses early in the Spring and then disappear for
    the summer.

  • Brittie - La Porte, TX 9a

    It honestly looks like a very mild case of fungus (blackspot, rust or whatever), probably brought on by weather conditions (too many cloudy days? too much rain?). I wouldn't be too bothered by it. The leaves will clear up when the weather does.

  • jerijen

    I've said this before, but I'll repeat it.

    It's easier, and better in the long run, to select roses that are resistant to the diseases common in your area.

    You mentioned buying 'Brandy,' for instance. Did you read the information on 'Brandy' in HelpMeFind?

    It reads (in part):

    "USDA zone 7b and warmer. Can be used for cut flower or garden. Vigorous. heat tolerant. Disease susceptibility: disease resistant, susceptible to blackspot . . . "

    Now, if you are in Canada, I'm suspecting you may not be in a "USDA zone 7b or warmer . . ."
    Also note: ". . susceptible to blackspot."

    'Brandy' acts in many ways like a Pernetiana rose. I would not expect it to be blackspot resistant, and I would not expect it to be cold-hardy. It is a lovely, lovely thing in CA, but I'm not sure it's well-suited to Canada. There are some really beautiful roses, though, that were bred for Canadian conditions, those might be better choices for you.

    And, FWIW, the use of many garden chemicals is forbidden by law in Canada -- which is perhaps the reason you cannot buy them there.

    While you're taking your break, Hrose, think long and hard about your gardening goals. When you said that aspects of rose gardening are "too much work", you stated the sentiments of the vast majority. The minority who are truly "into" roses, acknowledge the frustrations, but simply keep on keeping on attempting to provide our plants the best care we can. Frankly, I've no patience with anyone who loses name tags. How are you to properly care for a plant variety if you don't know what it is?

    Perhaps non-flowering shrubs would work well for you. Combining various textures, shades of green, growth habits can make for a lovely, relatively hassle-free garden space. To break any monotony, you might intersperse a few annuals. The possibilities for gardening WITHOUT roses are limitless.

    windeaux thanks but im not planting shrubs evergreen shrubs are all over the place here if not for roses i wouldnt be gardening at all

    can somebody point out which of my roses are disease resistant and which are not

  • buford
    11 years ago

    No, no one can do that unless they live next door to you and grow that rose. The disease resistance is subjective to area and even individual placement in the yard. Most HTs are not disease resistant, which is why people are trying to steer you to other types of roses.

    No rose is every going to always be spot free with no yellow leaves. That is just they way they are. They are not carefree, if you always want them to look perfect, you are either going to spend a lot of time fussing over them or be disappointed.

    HRose

    Your roses clearly show Rose Rust in stage 1 (the orange spots), stage 2 - yellowing and even stage 3) formation of little black spots - not to be confused with BS.

    Every gardener can and dare I say should? grow beautiful fragrant roses! I enjoy very few things in my life more than roses and have my days filled with their beauty and I am high on rose perfume and happiness. And neighbours, guests and people who walk by are astounded how well my roses are doing and performing.

    I can give you a list of roses that are doing exceptionally well for me - but it may not help you much.

    Like Jeri writes - Study! Study all the gardens nearby and see what roses you like and check the plants for years to see how they are doing - and ask gardeners growing them for advice - join a local rose society and see their gardens - nothing can replace local knowledge and experience!

    Certain roses that are doing well in some areas of the world may perform badly for YOU in your garden. But no one should be deterred from growing great roses.

    Some of my roses get a little rust - I watch these roses like a hawk - and inspect them daily and remove every leaf with orange spots - and I spray them a few times during the summer. But if they keep getting rust and I should spray more - I get rid of these roses. I will not spray more than once or twice or month. And out of maybe 150 different roses I grow - only about 15 cultivars needs spraying - and I will let them go if they keep needing spraying. Other gardeners will choose to spray more - that is their choice - but as much as I like my roses to be peak performers and look immaculate - and I have smitten the entire neighbourhood with my love for roses - that are much admired - I will let cultivars that needs more spraying than I am willing to do - go from my garden (and no - I do not give them to my neighbours - so the rust spores can come drifting with the wind back into my garden. I have given them 3-5 years to prove themselves and if they are RUST or Black spot magnets - they have got to go.

    I hope you will find good roses over the years that will do well for you and will bring you much joy and happiness. There are so many good roses - that I am sure you can find some that will do great in your garden too!

    "can somebody point out which of my roses are disease resistant and which are not "

    Pretty much none of them. I have yet to meet a single Hybrid Tea that didn't get Blackspot, in any climate.

  • dublinbay z6 (KS)
    11 years ago

    hrose, make life simple.

    Quit focusing on hybrid teas. They will get diseases.

    Instead, try a floribunda like Eutin. I don't remember if you ever told us what zone you are in (it should be listed next to your name where you put the word "none"), but Eutin is cold-hardy through Zone 4--so it is very cold hardy. It also is very disease resistant, as long as you plant it in full sun. It is a heavy cluster-bloomer (red), although between bloom cycles, it will go for a number of weeks without any blooms. Quite showy when in bloom.

    In the meantime, take a few minutes in front of each of your current roses and pluck off the yellow leaves and dispose of them in a plastic bag. There--now that the yellow leaves are gone, doesn't the rose look better? See how easy it is to deal with yellow leaves?

    Keep life simple.

    I think it's hard to tell how disease resistant a rose in your garden is going to be until you've had it for a while. Some roses get diseases like blackspot as babies, but then seem to grow out of it when a few years older. I don't know about all of your roses, but I suspect that Brandy may be the most disease prone. I wouldn't look at her cross-eyed just yet though. Give her some time and see what she does. Enjoy the flowers they all make and relax. Gardening is FUN! :)

    Grow gallicas, a lot of them. They don't repeat, of course, but in a cool climate the blooms can last a good while and you can stretch the season out with early and late ones.

  • hoovb zone 9 sunset 23
    11 years ago

    leave no exposed soil cover it all with grass would this prevent black spot?

    No. The BS spores will float through the air and attach to foliage without need to go to ground. The grass will increase humidity through respiration, and humidity encourages fungal diseases.

    Either tolerate some spots on your rose foliage, or don't grow roses. There are literally hundreds of thousands of different beautiful plants you can grow in your garden. No one has to grow roses--there are plenty of other genera to try and enjoy.

  • spiderlily7

    We all feel our way into the roses that please us so much, we'll take extra effort to cultivate them--or decide to grow ones that take next to no care. And starting out, it's so easy to be entranced by a rose's beauty we'll acquire it even as we're still learning the basics. Lo these many years ago, I was living on a mountaintop with winter wind chill that in effect created Zone 3 growing conditions. We're talking Canada here. And what did I choose as my very first rose? A Lady Banks Yellow, which of course promptly perished the first winter since she grows and survives only in warm climates. But that inspired me to start learning everything I could about roses. And the story's always good for a laugh when I'm talking to other rose people!

  • dara_gardener-Vancouver Island, Z8

    I'm very late coming to this discussion. It is now May 2019. I live in Nanaimo on Vancouver Island, zone 8. I grow an extensive collection of roses, all of which are no spray. If any of my plants show enough black spot to defoliate the plant, or rust for that matter, they are shovel pruned without hesitation. However that doesn't stop me having an entire yard of roses. For Toronto consider the Canadian bred roses grown on their own roots. They are all wonderful plants. 'Campfire' is outstanding. I also have great success with 'Violet's Pride' and 'Edith's Darling' from the Downton Abby series. An outstanding rose is 'Julia Child'. This yellow rose is in it's second year in my garden. Already a very sturdy plant with no disease problems at all. So the point is, don't stop growing roses. Grow roses with superior genetics. Also make sure you have good growing conditions. That means soil that is friable and water retentive, but not water logged. I use a combination of steer manure and peat moss mixed together to create excellent soil. When watering, don't wet foliage if possible. Water the root area. Make sure your roses are getting enough sunlight.
