Peat moss is a type of organic material formed from the accumulation of partially decayed plant matter in waterlogged conditions, primarily found in wetlands. It is commonly harvested for use in gardening and horticulture due to its ability to retain moisture and improve soil structure. This natural product is often used as a soil amendment, helping to aerate heavy soils and providing a lightweight medium for potting plants. Peat moss is also valued for its acidity, making it suitable for acid-loving plants like blueberries and azaleas.
