What is peat moss and where does it come from?

Peat moss, also known as sphagnum moss, is a type of moss that grows in wet, acidic environments, particularly in peat bogs and wetlands. It is formed from the accumulation of partially decomposed plant material over thousands of years, resulting in a dense, fibrous substance. Peat moss is commonly harvested for use in gardening and horticulture due to its ability to retain moisture and improve soil structure. Its unique properties make it a valuable resource, although its extraction raises environmental concerns regarding peatland ecosystems.
