A fiber extracted from the husk of coconuts used in floor mats, brushes, mattresses, and horticulture. High in sodium and potassium, coir is treated before distribution as a growing medium for plants by soaking it in a calcium buffering solution. Coco coir is frequently used as a substitute for sphagnum moss due to it being free of bacteria and fungal spores. It’s also a great snail deterrent and, when combined with vermiculite, can be used to grow mushrooms. It’s often seen used in hanging baskets.
