This year, I had a Food Coop organic yam sprout in the veggie bin. (Be aware, many grocery store yams are now coated with chemicals to prevent the yams and potatoes from sprouting) I don't like to kill accidental life, especially with such a strong will to live, so I hit Google to see if I could grow the little devils. I found this and this that told me how to get started.
I followed the directions and now have 3 little yam plants (with more on the way) in small pots of soil.
Of course, you can grow these in the ground but take some precautions. If you have gophers, some hardware cloth under your loosened soil should reduce the varmint's share of your bounty.
There is some goodness to the basket idea. In the hot, dry high desert, they could be moved either into partial shade in summer heat or full sun in the winter. These can also be placed near other plants to provide evaporative cooling and better humidity during the deep heat of summer and under some cover to prevent rotting during the monsoon. Yes, if I use baskets I'll need to grow a bunch of yams to cover their cost burden. The current price of organic yams is almost $2 per pound. Eventually I hope to support my habit from homegrown!
