Using Coconut Coir in the Garden Posted on 28 Sep 18:53 , 2 comments

From Mary's Heirloom Seeds,

COCONUT COIR BRICKS
Coconut coir growing medium comes from the coconut's fibrous husk (known as coir) that is bound together by lignin (known as pith). After the husk is immersed in water for 6 weeks, the fiber is extracted mechanically, and the pith is left behind as a waste product and stored in heaps to age. Since the pith comes from the fruit, it is quite naturally rich in nutrients. Coconut coir growing mediums are dehydrated and compressed into a compact form for easy handling. With the addition of water, coir expands to an easy to work with growing medium. 

The addition of water increases the volume 3 to 9 times, depending on the packaging of products. This process results in a 100% organic, biodegradable growing medium, making it a natural and safe growth medium of choice for growers.

Coconut Coir Bricks: Just add water!

-Unlike peat moss, which is highly acidic, coconut coir has a neutral pH level. Most garden vegetables and flowers grow best in neutral to slightly alkaline conditions. When you use peat to amend a garden bed, an addition of agricultural lime is often necessary to combat the higher acidity. With coconut coir, limestone isn't necessary unless the soil naturally has a higher pH level. Coir use results in both a monetary and a labor savings, since you don't need to purchase further pH amendments nor work them into the soil.

-Coir improves soil drainage in the bed while also helping to retain moisture in quick-draining soils. Since coir breaks down slowly, much like peat, it creates air pockets in the soil that allow excess moisture to drain away from plant roots. The coir itself holds onto some moisture so the drainage doesn't occur too quickly and the soil doesn't dry out completely. These dual drainage and retention properties allow coir to improve moisture management in both heavy clay soils and dry, sandy beds.

-Peat moss, which coir replaces as a soil amendment, takes centuries to regrow once harvested. Coir is completely sustainable since it is a natural byproduct of coconut harvests, and coconut trees produce new coconuts every year. Using the coir in the garden keeps it out of the landfill where it would otherwise go. Coir can take a century or longer to fully break down in these landfills, so it's more sustainable to use it to improve your garden soil.

Coconut Coir Pellets are great for seed starting
