Peat is the principal component of growing media in European horticulture. Growing medium. This is often seen in the compressed bales at garden centers and mass merchants. Water holding capacity, air porosity and bulk density are determined by the particle or fiber size of the peat. Long-fiber sphagnum moss is simply dried sphagnum moss, which eventually would die and become the peat moss of peat bogs. Pour-through (PT) is a nondestructive, effective, and convenient medium extraction method developed for peat-based media. 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). Long-fiber sphagnum moss is another alternative for soilless gardening. Sphagnum moss is a highly desirable growing medium with excellent drainage and aeration. These prevent the cells from collapsing when they dry out. As a general rule all houseplants need a growing medium that is sufficiently "open" and "loose" enough to allow its roots to grow. A growth medium or culture medium is a liquid or gel designed to support the growth of microorganisms or cells, or small plants like the moss Physcomitrella patens. 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. e. Sphagnum Moss. The peat is more decomposed than grower grade peat and has a brown color, with short fiber length.

Organic and wild-harvested, moss holds a special place among eco-friendly producers looking to outfit their operation with more natural components. Peat moss or Sphagnum moss are high humidity, good water retention 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. Throughout Europe the main growing medium available from former bogs is cut the peat. 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. It needs to be open and loose enough that water can flow through the soil but not so open that water literally just runs out the bottom otherwise your plant will have nothing to drink. Taiwan is the leading exporter of phalaenopsis and nearly all are produced in sphagnum moss. Origin of Sphagnum Peat Moss.

It possesses excellent water retentive properties while maintaining an oxygen enriched environment in which roots flourish and will not rot. The main characteristic of Sphagnum that makes it useful to Bonsai growing is its ability to hold a lot of water. One of the most important ingredients of soilless substrates, peat moss, began in peat bogs shortly after the last ice age about 12,000 – 14,000 years ago. Different organic materials are widely used as growing media for plant production. Each type of peat fulfills unique needs in different market segments. Since the fibers are almost non-existent due to complete decomposition, the fine particles in black peat pack tightly together. Sphagnum Peat Moss Production and Sustainability in Canada. Sphagnum moss is used for miniature orchid. Peat moss, or sphagnum moss, is accumulated bio-matter that develops over time in peat bogs. In Canada, there is an abundance of peatlands and producers follow "wise use" guidelines for the harvesting and preservation of peat bogs. Due to the fiber size, growing media produced with this grade of peat will have many smaller pore spaces and a slightly lower water holding capacity, slightly higher bulk density and a slightly lower air porosity than growing media made with grower grade peat. Did you know you could use moss as an eco-friendly growing medium. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Sphagnum Moss. So why does the myth that peat-based growing medium are sterilized / sterile persist? Sphagnum moss plants can hold 16–26 times as much water as their dry weight. Sphagnum moss has no roots and doesn't need to be planted in any medium. How do you make a growing medium? Falls Apart – Probably the biggest concern that a hydroponic grower should have about using sphagnum moss and sphagnum moss nutrients is that it is not an especially stable medium. However, in our study, S. subnitens had only a weak performance. 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. Typically, sphagnum peat moss is classified by its fiber size such as “grower grade” peat, fine peat, consumer peat or black peat. PRO-MIX® is a registered trademark of PREMIER HORTICULTURE Ltd.
