What Is a Coco Liner? (& Why You'll Love It!)

Posted by Arcadia Garden Products on

That coco liner is more than just an attractive addition to your hanging basket, it's an eco-friendly gardening superhero!

Find out how adding coco liners to your planters can make gardening even easier.

Eco-friendly movements and advances in technology have made gardening more and more popular. But sometimes, the best solution for your planting needs are the simplest.

Say goodbye to moss liners in your hanging baskets; coco liners are a growing trend with special advantages.

Read on to learn about how you can enjoy the benefits of coco liners in your garden.


What Is a Coco Liner?

Coco liners, also known as coco coir, are designed to hold dirt and plants inside wire containers. 

The coarse, brown fibers are harvested from the inner shell of coconuts, making them an eco-friendly, biodegradable, and healthy choice for your garden.

Coco coir is available as loose fibers, sheets, or pre-formed liners that fit neatly into your containers.

Not only do sheets and pre-formed liners come in multiple shapes and sizes, coco liners are flexible, making them easy to fit into your favorite hanging basket.


Plant Liner Alternatives

Why choose a coco liner over the many alternatives on the market? Before we dive into the many benefits of coco liners, let's see how the competition stacks up.

The most common plant liner materials are sphagnum moss, peat moss, burlap, and landscape fabric.

Sphagnum moss is a type of moss that grows on the surface of a bog or wetland. Like coco liners, it can be sold as loose fibers or compressed material. However, it doesn't hold moisture well and will need to be replaced every couple of years as it breaks down.

Peat moss, or sphagnum peat moss, is the layer of sphagnum moss that has sunk below the surface of wetlands. It takes up to 15 years for one inch of peat moss to develop. As a result, it is more acidic than coco liners and harvesting it can devastate the local environment.

Burlap is often touted as a more affordable alternative to coco liners, but they are not a true one-to-one comparison. Burlap is a much flimsier material, so you would need several layers of burlap to adequately hold soil in your containers. Burlap is also not as effective at absorbing moisture, so you will need to be vigilant about your watering habits.

Landscape fabric is breathable, affordable, flexible, and holds moisture well, but it leaves a lot to be desired in terms of beauty. Landscape fabric is supposed to be used as a weed barrier, hidden under a layer of soil and mulch; it wasn't designed to be attractive!


The Benefits of Coco Liners

Coco liners, on the other hand, combine the best features of the most popular plant liners into one convenient and effective product.

Moisture Regulating

Finding the right balance of moisture is key to gardening success. Not enough water and your plants wither and die. Too much water and you risk root rot and fungal growth.

Unlike their alternatives, coco liners can regulate your soil's moisture levels so that plants stay healthy.

Coco liners can hold up to 8x their weight in water, then slowly release it as the soil dries out. This makes watering your container garden a lot easier!

Peat moss tends to be slightly acidic, which can make it difficult to balance your soil's pH levels. Coco liners, however, have a neutral pH, as well as anti-fungal properties that can protect your plants from disease.

Coco liners also contain natural traces of potassium and phosphorous, minerals that enhance plant health.

Environmentally Friendly

 As coconut milk, coconut meat, and coconut water have become increasingly popular, liners are the perfect way to utilize the coconut fibers that would otherwise go to waste.

And because they are 100% natural, coco liners are also biodegradable! Plant them (along with your plants) directly into the soil or mix the liner into the dirt for a natural fertilizer.


Like any other material, no coco liner will last forever. However, coconut fibers are tough, resisting both time and decomposition.

A good coco liner should last through multiple growing seasons.

Coco liners have remained popular for many reasons, but one of the biggest advantages is their aesthetic appeal.

The natural look of a coco liner combined with a lush, vibrant petunia or geranium in a hanging basket makes a striking statement that blends seamlessly into any decor.


Making the Most of Your Coco Liner

Gardeners aren't the only ones that appreciate the advantages of coconut liners. Birds find them a great material for their nests, so if you have some aerial friends nearby, your liners might get pulled apart.

If your yard has a lot of avian activity, consider putting out a basket of straw, loose twigs, or even yarn to give birds an easily accessible source of nest material (so they'll leave your coco liners alone).

Coco liners are good at regulating moisture, but because the underside is exposed, a good amount of water will also evaporate into the air. To prevent this, place a plastic bag between your coco liner and the soil to hold moisture. Just be sure to cut a hole at the bottom of the bag first. Excess water will still be able to flow through, while still protecting the sides.

Coconut liners' pH is nearly neutral, so if you have plants that thrive on acidic soil, like blueberries, you might need to use another liner.

Follow these tips to make the most of your coco liners and your garden will be the envy of the neighborhood.
