I have often heard of the 3 Sisters but have never had the opportunity to try it. You raise another question in my mind Steven...For those of us with minimal planting space, what would be considered a good starting number of guilds for suitable polination to occur? I had not even considered that angle but it is a must isn't it? I would also love to see some photos as I have only heard "fables" of sister plants but have never seen it in action.
