TN, I've got lots of 9 and 10 year olds, and younger. Have had mixed results of course, but I do have a good bit scattered throughout the hills around here. For the most part it is pretty slow growing, so I let them go a little longer. Deer have been my biggest problem. They will browse anything out in the open. Especially when the plants get bigger. I do occasionally dig some, but no large harvests so far. It sure is fun walking around the woods looking at all of them in the spring time. Half or better are gone come September, but each spring is enjoyable to me.
