In the past, I've used part of my main garden to grow spuds. They keep well, I can pit them in-situ and at least here in AK, blast isn't a problem. I've had good production, but have decided to go with growing in pots. Last summer I tried something different. I used an old 30 gal trash can as a potato pot. Long story short - it was a disaster - zip. A learning experience, but no spuds. This summer, I used smaller pots. I got a few large spuds, but still less than I had hoped for. In looking on line for how others fine tune their spud pots, I ran across an interesting site (Allotment Diary) After looking at several of this guys videos, I have a better idea of setting up my pots and soil prep. I may even try growing spuds in a plastic bag inside of a gunny sack.... I'm starting to grow in pots to reduce my knee time (mine are both shot), reduce water/fertilizer use and to make 'harvest' easier. The G-kiddos are the biggest reason for this - they ran a smaller garden this year - too much 'school stuff' So I'm trying things that reduce work time and increase harvest, this as a demo for them. On the plus side, the school has a green house and garden allotments for each classroom. Take a look - the success this fellow has is beyond argument - I am envious.
