Coir, also known as coconut fiber, is a natural fiber extracted from the outer husk of a coconut. It is used in a variety of products such as floor mats, doormats, brushes, mattresses, and even car seats and furniture. Coir is also used in agriculture and horticulture as an organic and decorative component in soil and potting mixes. It is a sustainable alternative to sphagnum (peat moss) and peat from peatlands, which are becoming increasingly unsustainable. Coir is also useful to deter snails from delicate plantings and as a growing medium in intensive glasshouse (greenhouse) horticulture.

Coir has several advantages over peat, including being slower to decompose, sterile, free of weed seeds, and having a less acidic soil pH. It also improves air porosity in soils and moisture retention, making it easier to re-wet when it dries out, helping plants recover from dry conditions quicker and requiring less irrigation.

Coir comes in different forms, including blocks, bricks, bags, and bales. It is also used to create yarn, brushes, insulation panels, and packaging. Coir doormats are made from the long, brown fibers of the coconut husk and are eco-friendly, functional, and resistant to fading in direct sunlight.

India and Sri Lanka are the top coir producers, and most coir is processed where coconuts are grown. Coir is a sustainable material that has been used for centuries and has a wide range of applications in various industries.
