Coir pith, the by-product of dehusking of coconut fibre, is the spongy material that binds the coconut fibre in the coconut husk.   As an excellent soil conditioner, it now finds use as a good manure and in horticultural applications as a soil-less growing medium.  Coir pith is a substitute for peat moss which is widely in use in European countries and is made available in various forms like organic manure, grow bags, briquettes, discs etc.
