Potatoes too. Let them grow legs and chop them up carefully and put them just barely in the dirt. Cover with garden mulch or soil when they get about 4 to 6 inches tall and keep moist. I'm growing potatoes from a mulch pit I started 16 years ago. Threw what I thought were rotten ones in it one year and the whole pit turned into a potato mound. Best part of that mound is all the deer in the area know it is there and the dog water is right by it. Venison!!
