Sphagnum The moss inhibits the growth of microbes and reduces the need for chlorine in swimming pools. In New Zealand, both the species "S. cristatum" and "S. subnitens" are harvested by hand and exported worldwide for use as hanging basket liners, as a growing medium for young orchids, and mixed with other potting mixes to enhance their moisture retaining value. Peat moss is a critical element for growing mushrooms. The fungal mycelium grows in compost with a layer of peat moss on top, through which the mushrooms come out, a process called casing. Peat moss, dead or alive, is also a
Portlethen Moss saturated organic layers could actually rupture, spilling large volumes of mud and organic debris to surrounding fields, thus enabling a bed for further spatial expansion of the entire bog. Ultimately the colour of the moss waters became blood red in colour, from the successive organic decay and stagnation. Only in times associated with cattle grazing and significant human presence (probably the late Iron Age), would this process reverse and the bog reduce in size. A wide variety of sphagnum, sedges, rushes and other characteristic bog species inhabit Portlethen Moss. Sometimes insectivorous plants reside in mosses, since the soils are generally
