Tomato Blight - Reusing Canes

RedwingRedwing Posts: 1,458
My tomatoes got a little late blight last year, not much and only very late in the season.  Is is OK to reuse the canes this year or should I sterilise them first.  I don't use chemicals so is washing up liquid helpful to wash them in or is it not really necessary?

    Never had blight as mine are always undercover, which is easier, but I don't think it would be transmissable on canes, unless there was soil attached. That's where the spores lie.
    I expect if they were thoroughly cleaned it would be unlikely to have any, but perhaps a dunk in a bucket of mild disinfectant afterwards would help?

    They don't need cleaning due to blight, but a wipe over is good practise.
    Blight spores are around us all in the air throughout the year.
    It's only when conditions are just right for them and they take hold on a plant that it becomes a problem.

    Thanks both; have washed them in washing up liquid.  Last year was the first time in over 40 years of growing greenhouse tomatoes that I've had blight.  (Had it on outdoor ones a few times though.)
