Peat Moss is
It is slightly acidic pH and is organic and is partially decomposed material mined from the swamp and it has good moisture holding properties
Gardeners use peat moss mainly as a soil amendment or ingredient in potting soil. It has an acid pH, so it’s good for plants that like acidic soil, such as blueberries and camellias. Peat moss doesn’t contain harmful microorganisms or weed seeds that you may find in poorly processed compost. Peat moss is sometimes called sphagnum peat moss because much of the dead material in a peat bog comes from sphagnum moss that grew on top of the bog but there not the same.
It takes several millennia for peat moss to form, and peat bogs gain less than a millimeter in depth every year. Since the process is so slow, peat moss isn’t considered a renewable resource. Mining process releases massive amounts of carbon into the atmosphere, and the bogs continue to exhale carbon long after the mining is done.
Since it doesn’t compact or break down readily, one application of peat moss lasts for several years. Peat moss doesn’t contain harmful microorganisms or weed seeds that you may find in poorly processed compost.It holds several times its weight in moisture, and releases the moisture to the plants roots as needed. It also holds onto nutrients so that they aren’t rinsed out of the soil when you water the plant.
