I have not bought potatoes for decades. Most of the ones sold in supermarkets are not of good quality. Grew all my vegetables and fruit for many years and only relaxed on that a little more lately...am currently in the process of developing some pasture to produce my own meat- lamb and pork, perhaps beef too. Growing my own food is definitely important to me and potatoes are a great crop to plant to break in new ground...and while not everyone can do it I recommend it, if you can, as a very rewarding pursuit. One of my more rewarding gardening projects was growing potatoes from true seed (not the clones that are sold as 'seed potatoes')- I now have my own unique genetic line of potatoes which are delicious and hardy- they have streaks of purple through the flesh and on the skin a light blush of red. I call them revolution potatoes!
