Coir Bricks

What Is Coir?

Coir is a natural fibre extract derived from coconut husk. The Coir fibres are extracted from between the outer shell and hard internal shell of the coconut. The fibres are then screened, graded, washed and compressed into bricks. Coconut coir has many applications but is especially useful for gardening as an alternative to peat moss.


Advantages of Coir

  • Coir lasts longer in soil than peat moss
  • Coir is quickly and easily renewable
  • Coir is naturally free of bacteria, plant disease, fungal spores, weeds, seeds and pathogens.
  • 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.

Coir Production

Coconut Coir bricks are a 100% natural by-product of coconut harvesting, done using sustainable methods in India and Sri Lanka. The main areas where coir is produced is in Pollachi and the coastal region of Kerala.

Water Holding Capacity

A compressed coco coir brick, block or bale should be soaked in water for at least 1 hour before using. Coco coir fibers expand 5 to 7 times in volume when soaked in water. Because of its superior water holding capacity, coir has excellent air space and drainage. When used in sandy soils, coconut coir fibers help to keep nutrients and moisture close to plant roots instead of washing away. When used in clay soils, coco coir brick helps to break up hard-packed earth and move nutrients and moisture through the soil.

Soaking Coir Bricks

Once considered useless, coir is increasingly used as a growing medium by commercial greenhouse operations. Because of its superior water holding capacity, excellent air space and drainage, coir is useful in modern hydroponics and as a soil amendment for potted plants, containers and gardens. Coir is superior to peat moss and rock wool for structural stability, water absorption, and drainage and doesn’t decompose as quickly lasting longer in your soil. Harvesting coir does not have the environmental impacts of peat mining.
