Thanks, I have heard of doing that but our ground is so very wet in the winter that I have always thought they would rot from the wetness. It was really interesting though to see it done and they put a plastic cover over it to protect it from moisture. Don't think that would do much for my ground. It did make me wonder what would happen if I tried that with my big Portadora EE's. They are in a slightly raised bed at the edges of a patio. The stone and sand base with the red brick top of the patio would add some warmth to the ground and with large piles of leaves and straw on top of the open beds. It makes me wonder how they would do.
