Coir - a lightweight, 100% natural material derived from coconut husk. Compressed coir has a unique cell structure that allows it to expand and retain moisture.
When mixed with native soil, Expand 'n Gro™ helps loosen and aerate soil. It creates up to 90% more air space than native soil alone, so moisture and nutrients can reach plant roots. Even if you have heavy, compacted or clay soil in your garden, Expand 'n Gro™ makes it easier to work and up to 40% lighter. And, unlike traditional soil amendments, coconut coir breaks down slowly in the soil, so it improves native soil for multiple years.
Coir's unique moisture holding abilities help Expand 'n Gro™ retain more moisture than basic potting and garden soils and then releases water as plant need it to help prevent over or under watering.
