Coconut Coir is a 100% natural by-product of harvesting coconut. Coir consists of the coarse fibers extracted from the husk on the outer shell of a coconut. Because of its superior water holding capacity, excellent air space and drainage, coir is a useful soil amendment for potted plants, containers and gardens. Coir is a sustainable alternative to peat moss - it does not produce the same environmental damage caused by peat mining and grows quickly for harvest. In addition, coir is easier to hydrate and lasts longer in soil than peat moss. Coir's neutral pH of 5.8-6.8 allows it to efficiently release nutrients to plant roots and reduces the need to use dolomite lime in the garden.
