Had a bit of trouble though this year with my potato seed . I have for many years now bought Desiree from my allotment society and have usually had a good crop, but on harvesting them last year i lost half the crop to blight.
Not being deterred by this i ordered Desiree again this year, but when the seed arrived all three 2.5kg bags had a rotten potato in each bag. No way was i going to put them in my soil, so i went to my local garden centre and chose six different varieties all desease resistant.
I wonder if it was just a bad year for that variety so hopefully i will have better luck this year using different seed.
