Coconut Coir is a natural fiber made from the husk of ripe coconuts making them an idea liner for your plants and foliage! Coco liners, also known as coconut fiber pot liners, are made from the husk of ripe coconuts. These liners can hold a great deal of water, while releasing it slowly to allow plant roots to better take it up. Coco liners are porous and provide proper aeration and drainage, all of which promote proper root growth resulting in healthier, happier plants. Coco liners have a neutral pH (6.0-6.7) and contain small amounts of beneficial phosphorus and potassium. This makes them ideal for planting all types of foliage and plants.
