Coir is a byproduct of the fruit of the coconut palm. Until 25 years ago, the coconut fiber was known only as ropes, mats, carpets and similar products. Two thirds of the husk were regarded as waste, and ended up in landfills. With about 45 million tons of coconut per year, more than 60 million cubic meters of coir pith (40 million m3) and coconut fiber (20 million m3) are accrued.

Today we know that after careful preparation coir can be used as a versatile raw material for substrates and it has many uses.

The benefits of coir include the following:

  • Rapid water absorption
  • High aeration
  • High capillary action of water
  • High structure stability with little decomposition

With hydroponic cultivation and modern cultivation technology, coir has captured the production of vegetables. Compared to peat, cut flowers, such as gerberas and roses, have a longer cultivation time (in years) when grown in coir, and this also has economic advantages. Berry crops, such as strawberries, are increasingly grown in coir grow bags.

Coir is increasingly accepted in all branches of horticulture. Coir as a potting soil will achieve great popularity in the next few years. Coir meets all minimum requirements of an organic product.

Confidence has been created in the area of horticulture, however only due to the professional study of coir as a substrate starting material by the European substrate industry, and a consequent Quality Assurance, from the origin to the delivery.

Environmental friendliness

Coir has an excellent Life Cycle Assessment if all criteria are considered: Origin, processing, environment, transportation and human resources.

The Indian company „Sivanthi Joe Coirs“ fulfills these requirements with its certifications: RHP, RAL Quality Label "Substrates for plants", IMO Control Switzerland, MPS- ECAS ISO 9001 and SA 8000.

Today only a small part of the available raw coconut is used. In the next few years, the demand will considerably increase. However coir is a matter of trust. Not every origin and every supplier fulfills the high quality requirements.
