What is Coir?

coir Coir (pronounced “koyer”) is the fiber from the husk of the coconut, the part between the hard inner shell and the outer covering. It has long been used to make doormats, mattress and upholstery stuffing, rope, and fishing nets. KoirPeat™ is essentially a byproduct of the coconut industry; mountains of coir pith have accumulated in tropical countries where coconut palms abound. Coir pithhas been used as a planting medium for a variety of plants for at least two decades. Until recently its availability has been undependable and the quality highly variable. Nedia has been successful in manufacturing and marketing high quality coir pith under the trade name KoirPeat™. See the table below for KoirPeat™ characteristics compared to other peat based media.
Characteristics Spagnum Peat
(30-50% peat)
(50-100% coir)
Water-holding capacity Very high Extremely high
Air content (drainage) Low to moderate High, even immediately after saturation
Drying response Shrinks Does not shrink
Wetting after drying Hydrophobic; very dif ficult to rewet Rewets quickly
Longevity in hot climate 1-2 years At least 4 years, probably longer
Sustainability Mined from ancient peat bogs overexploited Renewable resource
Biological activity Fungus gnats and water molds thrive in it Fungus gnats seldom colonize it. KoirPeat™ supresses the growth of several pathogenic fungi.
Chemical reaction Neutral pH Very acidic (Mix is buffered to be slightly acidic)

Great Structural features

coir To understand why KoirPeat™ is so great for growing plants, we need to examine KoirPeat™ cells through a microscope. It reveals a structure that looks like bundles of drinking straws. These tough, hollow fibers can hold eight to nine times their weight in water, but the arrangement of the bundles allows water to pass easily between them. The space between bundles holds valuable air instead. End result is that KoirPeat™ stores water without becoming soggy, remaining light and fluffy, even when wet. These microscopic tubes make KoirPeat™ hygroscopic, which means "able to readily take up and retain moisture." Sphagnum peat moss, on the other hand, is hydrophobic, which means "tending to repel or fail to mix with water." You may have noticed that very dry peat moss forms a water-resistant crust or powder. Well, coir does not do that-it always absorbs water readily.

coir The tough outer husk of the coconut from which KoirPeat™ is derived, must protect its coconut seed from all kinds of harsh conditions so that it can germinate. This inherent decay resistant characteristic allows coir to last much longer than peat or bark-based potting soils. This translates to healthier roots for the plants and less repotting for the user.

coir Growing with KoirPeat™ may take a little getting used to, if you're accustomed to watering your pots by looking at or feeling the soil surface. The surface of coir-filled pots looks dry and feels dry to the touch because KoirPeat™ stores water inside its microscopic tubes. This unique property makes coir less hospitable to harmful root-rot fungi, algae and fungus gnats that thrive in moister conditions. Composition of KoirPeat™ makes it attractive to beneficial mycorrhizal fungi, however. Coarse coir fiber, used as landscape mulch, helps to repel snails and slugs, unlike bark mulch.

coir To make high-grade horticultural growing medium such as our KoirPeat™ raw coir pith must be processed to remove salts and minerals, and balance the pH for optimal plant growth. Without this treatment, coir pith contains toxic levels of salt and may have pH levels that prevent plants from accessing nutrients. Lower-grade coir and coir intended for other uses, such as small animal bedding, may be treated differently and may not be suitable for growing plants.

KoirPeat™ based potting mixes contain a blend of particle sizes: pith, fibers and chips. Finely ground coco pith, also called KoirPeat™, holds the most water and the least amount of air. KoirPeat™ fibers contain the most air, but least water. KoirChip™ falls in between the two and has the highest air to water ratio. Using different percentages of these three particles, we can make custom blends to suit the moisture and air needs of the plants that will grow in it. Our KoirPeat™ Blocks for example, has finely ground coco pith to help speed seed germination and support tender seedlings. KoirPeat™ Bricks come in compressed bricks for easy storage, making it more convenient and less bulky than other planting media. A compressed coir brick expands quickly to about 2 gallons of potting mix. Mix it with peat or other potting mixes, or use alone to increase the health of your plants and our planet.
