Coir (pronounced COY-er) comes from coconuts. It's what makes up the fibrous husks of the inner shell of the coconut and is used for all sorts of products, including rugs, ropes, brushes, and even upholstery stuffing. You're probably most familiar with it as those stiff, scratchy doormats and the fibrous liners used in hanging baskets. Coir is very rot-resistant, making it perfect for outdoor products. It is also becoming increasingly popular as a potting mix and organic soil amendment.

For a coconut by-product, coir takes a good amount of effort to get to market. The outer husks are soaked until the fibers can be separated and then cleaned. Then they have to be sorted and graded by size. Dark brown coir is from the familiar mature coconuts, but there is also a white version. White coir is from immature, green coconuts and is finer and softer. Some manufacturers also dye the fibers.

Coir goes by many names. You may find it labeled as coir-peat, coco-peat, coir fiber pith, coir dust, and other similar-sounding brand names.

Horticultural coir is a peat-like substance that is used in gardening and agriculture. It is made from the pith found between the fibers. The coir pith gets washed, heat-treated, sieved to remove large particles, and graded. Very often it is compressed into blocks or bricks, which need to be soaked before using. You may also find bags or bales of coir. They can be hard to locate, but as coir becomes more mainstream, it should become more accessible and affordable.
