Coco coir husk chips, an organic and natural mulch are made from coconut shells (husk) making them a highly sustainable alternative to other mulch options. The durable coconut fiber husk-chips can withstand inclement weather and break down at a more measured and even rate than other bark chips. High-quality coco coir 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. * Add room temperature water to fluff coco * Expansion volume - Each brick expands up to 2 Cubic Feet of coco mulch * Available Pack Size(s) - 1 Brick, 2 Bricks, 3 Bricks
