Advice from our specialist
Peat moss remains the primary component for casing layers in the cultivation of mushrooms. Peat moss is combined with limestone and other materials to induce mushroom pinning and development. Fibrous peat works well to hold large amounts of water. In the last several years, we have seen the introduction of humus-type peats, which are used alone or blended with fibrous peats to produce a slower, more erratic pinning of mushrooms. Some growers prefer this casing blend, since mushrooms can be picked over several days instead of large flushes all at once.
