Coco coir mix bricks support your plants all year long. The bricks do double duty: they retain water, making sure plants never go thirsty, but due to their texture, they also offer excellent drainage properties. Plants are no longer at risk of "drowning" in too-packed or over-watered soil. Instead, plant!t's ideal consistency gives them room to breathe and for roots to grow freely, capturing that essential air-to-water ratio for your biggest growth yet. Implement this pathogen-free media to your potting soil or in place of bark as an attractive and all-natural ground cover. Each pack contains 3 bricks.
