Hi all, so while I was in town yesterday I decided to purchase a red yam, a sweet potato and a white sweet potato. I was thinking about planting them and letting them grow and harvesting the leaves and giving my torts 4 or 5 leaves cut up into there weekly salad mix. Is this a good idea? I read they are edible but really couldn't find any hard facts about how much to feed, I do know they have a higher phosphorus to calcium level. Any info would be great thanks in advance.
