What are peoples' experiences of growing Sarpo potatoes this year?
We have grown Sarpo Mira for a number of years now and it has always shown the blight resistance claimed of it...until this year. Ours succumbed to late blight only shortly after out totally unresistant Arran Victories.
I'm wondering if its a new strain that has developed, and started to render Sarpo Mira less resistant - as happened with Lady Balfour before it. Any other thoughts on latest blight resistance/ proneness welcome
