I have grown Charlottes from bought seed tubers for several years but for the last two years the new potatoes formed normall and then sprouted and started to grow again, before I can harvest them. We live in the S.W of France but have been growing vegetables here and in Uk for the last 30 years without this problem. Please can anyone tell me where I am going wrong.
