It typically can have some small amount of tree roots (often called sticks) that are naturally present with the peat moss and are not all eliminated during the screening process in order to maintain a good quality peat fiber. The coarser the peat fiber, the greater the air porosity of a growing medium.

In summary, the grade of sphagnum peat moss used to produce soilless growing media will greatly influence the bulk density, water holding capacity and air porosity which will determine the use of growing media in plant production. It looks similar to coarse peat as it still has decent fiber, but does have slightly lower air porosity and water holding capacity as well as a little higher bulk density than fine peat moss. This sterilized medium is becoming more widely used. plug trays with sphagnum moss as the sole growing medium. Origin of Sphagnum Peat Moss.

There are many qualities of sphagnum moss make it a good growing medium for that epiphytic orchids. The finer the peat fiber, the higher the water holding capacity and the greater the bulk density in a growing medium. The particle or fiber size of peat moss is one of the most crucial factors in determining the type of the growing medium and the crop production it is used for. Sphagnum Moss. The grade or particle size of the peat moss influences the amount of pore space in a soilless growing medium. Sphagnum Moss. Sphagnum moss is preferred, used for growing orchids. sphagnum moss as media was found to have a significantly better vegetative growth. This is often seen in the compressed bales at garden centers and mass merchants. Sustainable alternatives for peat are needed, as peat extraction and use has many negative effects on the environment. Interest in sphagnum moss as a medium has increased, mainly due to the introduction of New Zealand sphagnum moss. 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. Sphagnum moss is also the result of decomposed bog plants, but sphagnum moss is harvested while the plant is still alive and floating on top of the water. It requires substantial capital to develop peatlands and establish processing facilities and transportation networks. “This picture shows different types of peat based on the degree of decomposition. This makes it better for use in consumer growing media, as the consumer generally does not water frequently, or it can be incorporated directly to condition garden soils. Premier Tech Grower Services Representative. | Lance Lawson. An important characteristic of the sphagnum cells is that they have lignified walls in the form of rings, spirals or plates. Sphagnum moss is used for miniature orchid. This limits air flow, which limits movement of water vapor, causing this type of sphagnum peat moss to dry out very slowly between waterings. Pour-through (PT) is a nondestructive, effective, and convenient medium extraction method developed for peat-based media. By keeping peat suitably wet, optimum conditions of moisture and aeration can be maintained. Sphagnum moss plants can hold 16–26 times as much water as their dry weight. Throughout Europe the main growing medium available from former bogs is cut the peat. Since consumer peat is a little more decomposed, it will dry out slightly slower than coarse peat. Unlike some other more stable growing media, such as hydroton or perlite, it can fall apart. Sphagnum moss has no roots and doesn't need to be planted in any medium.
