The invention provides a method for cultivating Sphagnum that has been applied to a surface of a field, the method comprising controllably irrigating the Sphagnum, wherein the controllably irrigating comprises applying water to a surface of the Sphagnum and/or to the surface of the field. The invention also relates to Sphagnum obtainable by a method of the invention.

A method of collection of sphagnum moss comprising a motorized cutting and collection of at least a portion of the sphagnum moss. The cutting is performed in a direction substantially parallel to the ground and in a direction substantially vertical to the ground, while leaving the sphagnum moss anchored to the ground.

An air purifier using moss, of the present invention, presents that a plurality of light-transmitting members passing through a moss sheet in the height direction of moss are provided so that sufficient light may be provided to the lower portion of the moss by the light-transmitting members. In addition, the present invention relates to an air purifying system using moss wherein the air purifier using moss is sprayed with an appropriate amount of water at the appropriate time, and an operating method thereof. An air purifying system of the present invention comprises: an air purifier comprising moss and a display unit; and a sprayer that communicates with the air purifier and sprays the moss with water, wherein the air purifier detects water spray from the sprayer and changes information displayed on a display.
