Coco husk chips, organic and natural mulch are made from coconut shells (husk) making them a highly sustainable alternative to other mulch options. Coco Husk chips absorb water and retain it, slowly releasing over time. Husks cut into chunks; the coco husk chips allow for better aeration and water flow to plants and are ideal for soilless plants like orchids and as landscaping mulch. Commonly mixed with coco coir growing medium to provide better aeration for plants.
