I've planted them for the past 5 years or so . They take a long time to grow , what kind did you get ? I've tried different one but Beauregard seems to do best for me so that's the only variety that I will plant . They are pretty easy to grow and the bugs don't seem to bother them , I did have problems on year where the vines looked great but the potatoes were very skinny , I might have use too much fertilizer with nitrogen 5-10-10 is what I've read they want . I think that year I used Miracle-Grow which is 24-8-16
You wait until the vines die off then dig them up like regular potatoes ( that what I do ) you don't want them in the ground too long after that because they will start to rot if the grounds wet , then they want them cured but I just put them in the basement .
