I just started my first garden. I have radishes and squash is almost ready. I've got beens, watermelon, cantaloupe, carrots, and a few other plants that have grown but nothing eatable yet. It's really awesome growing things from seeds. The plants you mention, Yucca and sorgum, I don't know about. I don't think I will grow wheat. I think I need more space and equipment for that. I'm not a farmer, just built a little greenhouse. Thanks for your input.
