The Canadian sphagnum peat moss is a renewable resource, harvested each year when the snow receeds from the lesser Slave lakes and across the north. The environmental concern is with the non-renewable peat moss harvested in the southern U.S.

However, fine-grain humic compost provided by greenery recycling centers across the U.S. is far less expensive (free for local residents) and a good substitute. Depending what it is made from, the fibers will break down faster and hence adding horticultural sand to the mix is a good idea.
