The use of sphagnum peat moss as a component of horticultural growing media has been very important because of the unique properties of the sphagnum cells to hold and release water.
The sphagnum cells are thin-walled cells with large cavities and their function is to absorb and transport water. An important characteristic of the sphagnum cells is that they have lignified walls in the form of rings, spirals or plates. These prevent the cells from collapsing when they dry out. By keeping peat suitably wet, optimum conditions of moisture and aeration can be maintained.
The functions of a growing medium are: a water reservoir for plant uptake, a nutrient holding/exchange system, a place for gaseous exchange for root systems and an anchor point for a plant's roots.
