    This year the Black Spot has got away from me. Its a pity as the roses have been amazing up to now.

    I'd like to try to regain control, and to that end I have been "hoovering" up all fallen leaves (actually I use the leaf-blower to blow them to one end, and then gather them up).

    But as we move into Winter the wetness will make it harder to separate the leaves, and I would like to mulch the beds with manure, which will make it harder still.

    My inclination is to cut them back now, to a point that will leave zero leaves on the plant, and thus I will be able to pick up all the leaf litter before winter, and hopefully reduce the chance of Black Spot overwintering.

    And then adopt a much more stringent spraying regime next year, whilst praying for a drier summer!

    I normally half-prune in the Autumn, to prevent wind-rock, and then hard prune in Feb/Early-March, so this would be a variation for me :)

    I'd appreciate your thoughts please.

      Good afternoon Kristen excellent method my friend ,I have actually just given some of mine this treatment(not all of them)just the affected ones;) I can already hear all my local Rosarian Club friend's saying are you sure,Oh its alright Woo is always experimenting;) It's not a method I would recommend to other Rose grower's ,but then people are never surprised at my action's where Roses are concerned but I am all for an early start to defeat Black Spot:)

        :smile: Very good point Kristen.
        I have been pruning off affected branches for some time now with the same view in mind.
        Most are reshooting and flowering,some or not.
        I don't normaly spray but maybee next year I might.
