I'm not talking sweet potatoes. Or at least I'm pretty sure I'm not. The organic store near me has several kinds of sweet potatoes and one thing they call "yams". They grew well for me in the past but I struggle to get slips from them. I've tried cutting them in half and setting them in water. I've tried partially burying them in damp potting soil. I'm out of homegrown ones so I just picked up a yam from the store. I'm going to try the toothpicks in the glass of water (uncut full yam) unless there's another way I don't know of?
