Coco liners are constructed of coarse fibers from a coconut. You will use less water while watering your plants as the coco liner retains an abundant amount of water that is slowly released into the soil so that the roots can best take it in. That means no wasted water! Coco liners are biodegradable, so you can feel good about using them because they are friendly to the earth. This coco liner is not only a beautiful addition to your garden, it is also the healthiest choice for your plants!
