By weight, coir fibers account for about one-third of the coconut pulp. The other two-thirds, the coir pith (also known as coir dust), has generally been considered a useless waste material. Although it is biodegradable, it takes 20 years to decompose. Millions of tons sit in huge piles in India and Sri Lanka. During the last half of the 1980s, researchers successfully developed processes to transform coir pith into a mulching, soil treatment, and hydroponic growth medium that is used as an alternative to such materials as peat moss and vermiculite. Coir growing media has a high water holding capacity with excellent drainage and aeration.
Promotes strong root growth and plant vigour.
Absorbs water readily and re-wets easily.
Reduces watering frequency without plant stress.
