Coir (coconut fiber) is a completely natural byproduct of the huge coconut growing industry of the island of Sri Lanka. Coir is an excellent growing medium for all kinds of containers and baskets. Improves other potting mixes when you blend them together. It retains plenty of moisture, but is very porous which allows for good air circulation and healthy root development of seedlings and cuttings. It is sterilized for freedom from weeds and plant pathogens.
