Often growing media produced with this grade of peat will have a little more peat dust, but virtually no sticks. The physical properties of growing media that sphagnum peat moss mainly affects are: bulk density (which is the dry or wet weight (mass) of the growing medium), water holding capacity (which is the volume percentage of water retained after a saturated growing medium is allowed to drain), and air porosity (which is the measurement of the volume of pore space occupied by air after a saturated growing medium is allowed to drain). You can tell by the way he treated and left the roots, how he handled the tree, and what he had growing around him that his … The grade or particle size of the peat moss influences the amount of pore space in a soilless growing medium. However, it tends to dry out faster than the other grades of peat because the peat packs loosely in containers, allowing water vapor to escape from the growing medium.

The medium seems suboptimal for, for example, S. subnitens, the species with the highest productivities out of 31 peat moss species from Sphagnum‐dominated wetlands (Gunnarsson, 2005). This type of peat has maximum air porosity over the other grades and the highest water retention. Sphagnum moss is an excellent medium since it allows air to circulate freely around the roots of the orchid. Since consumer peat is a little more decomposed, it will dry out slightly slower than coarse peat. 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. Mycorrhizal fungi live in symbiosis with the roots of a large variety of plants, including trees, shrubs, annuals and perennials. The peat on the left is grower grade, middle is consumer, and the one on the right is almost black peat. The finer the peat fiber, the higher the water holding capacity and the greater the bulk density in a growing medium. The coarser the peat fiber, the greater the air porosity of a growing medium. Pour-through (PT) is a nondestructive, effective, and convenient medium extraction method developed for peat-based media. It requires substantial capital to develop peatlands and establish processing facilities and transportation networks. var.

It is a great additive to drier mixes if you need to enhance the moisture-holding capacity, and it is an absolutely fantastic medium for a wide range of orchids if used all by itself. Sphagnum moss, which has very different chemical and physical characteristics compared with other soilless media, is commonly used as a substrate to grow Phalaenopsis in countries such as Japan and Taiwan. Water holding capacity, air porosity and bulk density are determined by the particle or fiber size of the peat. How do you make a growing medium? There are many qualities of sphagnum moss make it a good growing medium for that epiphytic orchids. New phalaenopsis/ Pure sphagnum moss as a potting medium Astrid.

Most peat is harvested in Finland, Ireland, Sweden, Germany or Canada. Peat fines are used in growing media for small cell propagation, seed germination and plug production. Sphagnum moss definitely has a place in bonsai culture, mostly in remedial applications, but it's unsuited for use as a stand-alone long term medium. Black peat moss is a highly decomposed, very fine particle size peat that is usually used  for soil amendments. Mushroom casings material is produced with this type of peat and will have a high bulk density, fairly high water holding capacity and a low air porosity. 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. Unlike some other more stable growing media, such as hydroton or perlite, it can fall apart. Many people know sphagnum moss as the pretty lining to a forest floor, but it is also a powerful medium in hydroponic gardening.
