Mosser Lee Long Fibered Sphagnum Moss Has Many Uses For The Home Gardener. I like to put a layer on top of the soil for large potted plants and houseplant trees. It offers a finished look, mulches the soil and makes it easy to see when watering is needed. You can also line wire baskets, fill topiary forms, use for soil-free growing and air layering. This organic moss is a renewable resource harvested from perennial live plants that grow in the rich Wisconsin marshlands. Can absorb up to 20 times it's weight in water. Package contains 432 Cu. In.
