This sheet moss is dried and preserved so no watering necessary! The best application for moss of this type is using it as a “ground cover” in your Tillandsia Display. These are flat pieces, not puffy like the other mosses we sell. Sheet moss works great as a gap filler in cork bark, or to cover pebbles in potted Tillandsia or as accent pieces on wood displays. You will receive enough moss to cover an 8”x8” area - similar to what you see with the potted plant in our product photo.
