Supamoss: This is the lining for hanging baskets that's supposed to help keep the plants hydrated longer. It's also supposed to last longer than the cocoa mats. We had a hanging basket demonstration last night at our garden club mtg. The shiny side gets covered with soil, and the mossy side facing out. Anyone who wanted to could take a piece from a long roll the speaker brought. She ordered a roll and said the roll cost about $150. and would fill 16 baskets. I'm going to try it. Hope the squirrels don't like it.
