  • Black Spot on Rose

    I have a climbing rose on an arch (forgotten the name) and it's got black spot really badly.
    Is there an organic treatment, what's the best thing to do?

    not that I know of Sue. Roseclear will sort it or pick off the affected leaves and any that are on the floor and mulch in winter this will stop any overwintering spore from splashing up in the winter ( or should that be summer) rains

      Yes, you must pick off and bin or burn any affected leaves.
      Don't let any fall to the ground, for the nasty fungus will live in the ground, waiting to reinfect the poor rose.

      Roses just are prone to blackspot. There ain't a lot of point stressing about it too much.

        Ironically the best roses I have ever seen were growing in the central reservation on a dual carriage way!! They were as clean as a whistle no aphids or blackspot - So petrol fumes aren't all bad !!

          Alot about roses is knowing when and how to prune them, I work by halves, cutting back the new growth by half in winter and selecting several strong stems with plenty of air circulation. This creates a strong root system and with a thick mulch every year, you have a better chance of fending off black spot but with wet weather, you're bound to get it, so pick of the infected leaves and burn them. I spray mine with seaweed too.
