Peat = partially decayed organic matter that is unique to peatlands and bogs. Peat forms in wetland conditions, where flooding obstructs flows of oxygen from the atmosphere, slowing rates of decomposition.

Most currently supplied planting substrates are based on recipes relying on quality peat.

Different types of peat by plant community it comes from:

  • Sphagnum Peat - the common peat, consisting mainly of partially decomposed parts of Sphagnum moss. It is the key type of peat for use in agriculture and horticulture
  • Hypnum Peat – consists mainly of stems and leaves of various species of the Hypnum moss.
  • Reed Peat – consists mainly of reeds, including Phragmites andScirpus.
  • Sedge peat – mainly stems, leaves, rhizomes and roots of different species the of sedge and Carex families.
  • Reed-sedge Peat – mixture of reeds, sedges and other non-moss fibers.
  • Carex Peat – peat with significant component of Carex plant remains.
  • Peat humus – fully decomposed peat, original plants cannot be determined.

Types of peat by their age:

  • Fibric peat – relatively young mosses that are only partially decomposed, usually with high water-absorption ability, low pH, low volume density and low dry matter content.
  • "Hemic" peat -  medium decomposition, older and more decomposed than fibrous peat.
  • "Sapric" peat -  the oldest and most decomposed peat, its colour ranges from dark brown to black. It is an excellent source of energy and is used as fuel in many parts of the world.
