I've heard of people growing spuds in piled up tyres, does it work? Also seen offers in the paper of planters (basically large pots), with seed potatoes ready to plant. I can't qute picture how they work, do you just harvest the whole pot's worth in one go (one plant?, two plants?) when its ready, don't really understand, and need MN help!
Sure this has been done before, but can't find anything...
