Peat moss, also known as SPHAGNUM, is a type of moss that grows in wet, acidic environments. It is commonly used as a soil amendment to improve soil structure and drainage, and to increase the amount of organic matter in the soil. Peat moss is also used in horticulture and gardening to help retain moisture and nutrients in the soil. It is an important component of many potting mixes and can be used to create a nutrient-rich environment for plants.
