Please can I get some advice on blackspot on my roses. I cannot see any bugs at all.
Were does it come from and why. I got an organic spray but it's not gone away. I'm gutted.

    The girls will be able to advise. I think some are more prone than others, and black spot is an easily spread fungal disease, but I know zippity doo dah about roses, so the experts will help you properly.
    A photo of the problem plant will help too  :)
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...

    I'm struggling with blackspot on slot of my roses. I've tried an organic spray but new leaves have now got black spot. Were does it come from and why does it happen??.

     Luckily it's not on my new David Austin rose. DANNAHUE.

    To be honest in my experience if you have roses, you have black spot. Just remove the affected leaves as soon as possible and concentrate on making healthy plants that will cope. I wouldn’t use any chemical on any plant in my garden. 
    I visited David Austin roses recently, all the roses in the gardens had black spot. 
    Just be glad you are not a pirate!
