What is Coconut Coir?

Coconut coir is a natural by-product of coconut harvesting. It consists of the coarse fibers extracted from the husks of coconut shells. It is a renewable resource.

How to Use:

Coir is compressed into blocks for easy handling and storage. Adding water causes the coir to expand 8-10 times its original volume. Soak coir in water for one hour to expand to 16-20 gallons.

Growing Medium

To use coconut coir as a growing medium, mix with topsoil and add compost to provide organic nutrients.

For garden beds and landscapes, add one part coir to two parts topsoil. For containers and potted plants, add one part coir to two parts soil or potting mix.

Seed Starting Mix

Coir is great for starting seeds and cuttings because it maintains a consistent level of moisture and it is naturally disease and weed free. It can be used as a hydroponic growing medium to facilitate seed germination.

Soil Amendment

When used in sandy soils, coir helps to keep nutrients and moisture close to roots instead of leaching away. When used in clay soils, coir breaks up hard compacted soil, so nutrients and moisture move through the soil.


Mix with water to expand coir. Add two parts coir to one part green organic material. Use 1:1 ratio when mixing with brown organic material. For best results, allow coir to dry in the sun for 30 minutes to evaporate excess moisture.

Coir can be used as bedding material for worm composters. It controls moisture and improves the quality of worm castings, which go into your garden.
