Halamanin's Dried Sphagnum Moss is useful for a variety of gardening and crafting purposes.
You'll often see it used for creating a Kokedama (which is a moss ball planter), seed starting, as a planting medium for orchids, as a potting soil amendment, for carnivorous plants, for lining baskets, or for other art projects.
It has a neutral pH level and is great for retaining moisture in the soil.
It is also light and doesn't become overly soggy though, so it means your plant is less likely to be bothered by root rot issues.
