Great idea! I can't do much composting here in the winter because I can't get to my compost bin in the snow. And I won't be trenching anything around here for a good long time, but I wonder if I could ziplock the smoothies, freeze them, and use them next spring? I might experiment with that and see what happens. I do put all my banana peels by my roses, but I just throw them down whole and they disintegrate very quickly. Food for thought...parden the pun!
