How to Use Coco Liners

Updated February 21, 2017

When gardening with wire hanging baskets or window boxes, you must have an insert such as a coco liner at the bottom and sides to keep the potting soil from falling through. These liners are made from the brown fibre coir of the coconut shell. Organic coco liners help to maintain moisture within the soil that the plant roots can access during times of intense sun and heat.

Select a container large enough to hold the coco liner. Fill the container with warm water. If the coco liner came as a large roll, unroll the liner and cut the amount you will need. Submerge it below the waterline. Allow the coco liner to soak for one hour. Soaking the liner in water will allow the coco material to be pliable for bending and shaping.

Lay the wire hanging basket or window box on a flat surface. Remove the coco liner from the bucket of water and allow the excess water to drain away. Insert the coco liner into the basket or window box. Push down the bottom of the coco liner so it is flat against the bottom of the basket or window box and press the liner flat against the sides.

Trim off any excess coco liner sticking up from the top with the shears, leaving at least 1/2 inch of liner above the rim of the basket or window box.

Pour potting mix into the basket or window box, leaving at least 3 inches of space below the top rim. With your fingers, push holes into the potting mix twice as wide and twice as deep as the plant's roots. Place one plant into each hole and pour enough potting mix into the basket or window box to cover all of the roots.

Place the coco-lined container in an exterior area that gives the plants their recommended amount of sunlight. Water the plants as soon as the potting mix feels dry.
