If you’re looking for a natural, renewable growing medium that’s perfect for your houseplants, you might want to consider using coco coir. Coco coir is made from the fibers of coconut husks and is an excellent alternative to peat moss, which is not a renewable resource. Coco coir is not only environmentally friendly, but it also offers many benefits for your plants.
One of the main benefits of using coco coir is that it retains moisture well, which means you won’t have to water your plants as frequently. This is especially useful if you tend to forget to water your plants regularly. Coco coir also has a neutral pH, which makes it an ideal growing medium for a wide variety of plants. Additionally, coco coir is free of pests and diseases, which means you won’t have to worry about introducing harmful organisms to your plants.
If you want to know how to use coco coir for houseplants, keep reading. We will share a few tips and tricks so you can use this growing medium for your plants.
What is Coco Coir?
Coco coir is widely known as coir, coconut fiber, or coco fiber. It comes from the husk of a coconut fruit. The process for removing the fiber includes soaking the husk in water so that the fibers can be removed. The fibers are washed, spun, and collected into a brick-like, compressed form that absorbs water.
It is a popular choice for growing plants because it is renewable, sustainable, and environmentally friendly.
Types of Coco Coir
There are three main types of coco coir: coco peat, coco fiber, and coco chips.
Coco peat or coco pith is the most commonly used type of coco coir. It is made from the finely ground coconut fibers and is often sold in compressed bricks or blocks.
Coco fiber, sometimes called coir fiber, is a coarser material made from the longer fibers of the coconut husk. It is often used in hanging baskets or as a decorative mulch.
Coco chips are larger pieces of coconut husk that can be used as a soil amendment or as a decorative top layer.
One of the benefits of using coco coir for houseplants is that it is an inert material, meaning it does not contain any nutrients or minerals that could harm your plants.
This allows you to have more control over the nutrients your plants receive and can help prevent over-fertilization.
Can Coco Coir Replace Potting Soil?
On its own coco coir lacks the nutrients plants need to grow and thrive, but mixed with other mediums like perlite and compost, it can create a top notch potting mix that can be tailored to meet your plant’s needs.
However, coco coir can be used on its own in certain gardening situations. For example, hydroponic gardening is a great use for coco coir because it is able to provide adequate support and moisture for plants without the need for nutrient-rich soil.
Additionally, coco coir can also be used as a soil amendment to help break up hard clay soils so that nutrients can be more easily absorbed by the plants.
Advantages of Using Coco Coir for Houseplants
Excellent Water Retention
Coco coir has excellent water retention capabilities, which means your plants will have access to moisture for a longer period of time.
This is especially useful if you’re someone who tends to forget to water your plants regularly. Coco coir can hold up to 10 times its weight in water, which means you won’t have to water your plants as frequently.
Aeration
Coco coir is also great for aerating soil. It allows air to circulate around the roots of your plants, which is essential for healthy growth. If you’re growing plants in containers, this can be helpful to avoid situations where the roots can become compacted and suffocate. Coco coir helps to prevent this by providing a loose, airy growing medium.
Neutral pH
Coco coir has a neutral pH, which means it won’t affect the acidity or alkalinity of your soil. This is important because different plants require different pH levels to thrive.
Using coco coir as a growing medium ensures that your plants have a stable pH level, which is essential for healthy growth.
Insect Free
Coco coir does not attract bugs and plants that are growing in coco coir are less likely to be attacked by pests. For example, it can deter fungus gnats.
Hydration
Coco coir helps to conserve moisture, which means your plants won’t dry out as quickly. This is especially useful if you live in a dry climate or if you’re growing plants that require a lot of water.
Disadvantages of Using Coco Coir for Houseplants
There are some disadvantages to using coco coir that you should be aware of before incorporating it into your houseplant care routine.
Overwatering
One of the biggest disadvantages of using coco coir for houseplants is that it has a high water retention capacity. This means that it can easily become overly saturated, leading to other issues.
Some gardeners will soak their house plants with coco coir in the anticipation that it will slowly saturate. This is not necessary, you can water your plants as usual. To prevent overwatering, it’s important to monitor the moisture level of your coco coir regularly and adjust your watering schedule accordingly.
Coco coir does hold water but it is not always distrubuted evenly. So when you are checking the soil, dont just check the top where it may be dry, you will also need to check down into the soil.
Root Rot
Of course overwatering can lead to root rot, a condition in which the roots of a plant become damaged and begin to rot.
This can be particularly problematic when using coco coir, as the material retains moisture and can create a breeding ground for harmful bacteria and fungi.
Compacting
Another disadvantage of using coco coir is that it can become compacted over time, which can restrict the flow of air and water to your plant’s roots.
This can lead to stunted growth, nutrient deficiencies, and other issues. To prevent compaction, it’s important to regularly fluff and aerate your coco coir to ensure that it remains loose and well-draining.
Downsides
It’s also worth noting that coco coir is an inert growing medium, meaning that it contains no nutrients.
This means that you’ll need to supplement your plants with hydroponic nutrients to ensure that they’re getting the nutrition they need to thrive.
Additionally, some gardeners have reported issues with salt buildup in coco coir, which can negatively impact plant growth and health.
Coco coir can be expensive, but if you plan on using it in potted plants or container gardens, the cost isnt that bad.
How to Use Coco Coir for Houseplants
.Here are some tips on how to use coco coir for your potted plants and house plants. We will discuss how to prepare coco coir bricks, the coco coir to water ratio and more.
Preparing Coco Coir Bricks
Before using coco coir, it is important to prepare it properly. Coco coir comes in compressed blocks or bags and needs to be hydrated before use. Here’s how to prepare coco coir for your houseplants:
- Place the compressed block or bag of coco coir in a large container.
- Add water to the container until the coco coir is fully submerged.
- Let the coco coir soak for at least 30 minutes or until it has fully expanded.
- Drain any excess water from the container.
The coco coir to water ratio will depend on the specific brand and type of coco coir you are using, as well as the stage of growth of your plants.
In general, a common coco coir to water ratio for seedlings is 1:1, which means equal parts coco coir and water by volume.
Weighing the coir by grams and multiplying it by 4.75 will give you an idea of how much water weight you need – if too wet multiply by 4.50 for your sweet spot.
It’s important to note that coco coir can hold a lot of water, so it’s best to start with a lower ratio and adjust as needed to avoid overwatering your plants.
You can also test the moisture level of the coco coir by squeezing a handful – if it is damp but not dripping, it’s ready for your plants.
Mixing Coco Coir with Other Growing Mediums
Coco coir is often mixed with other materials to create a well-draining potting mix. Here are some materials you can mix with coco coir:
- Perlite: Perlite is a lightweight volcanic rock that helps improve drainage in potting mixes.
- Sand: Sand can be added to potting mixes to improve drainage.
- Vermiculite: Vermiculite is a mineral that helps retain moisture in potting mixes.
- Sandy soil: If you have sandy soil, you can mix it with coco coir to improve its water retention.
To mix coco coir with other growing mediums, use a 1:1 ratio of coco coir to the other material. For example, if you are mixing coco coir with perlite, use equal parts of each.
Watering and Fertilizing with Coco Coir
Coco coir has excellent water retention properties, which means you may not need to water your plants as frequently. However, you dont want your plants sitting in standing water, as this can lead to root rot. Here are some tips for watering and fertilizing with coco coir:
- Make sure your plant pot has drainage holes to prevent water from accumulating at the bottom of the pot.
- Before watering your plants feel the top inch of soil feels dry to the touch. You may need to dig a little deeper to make sure only the top soil is not dry.
- Use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20 to provide your plants with essential nutrients.
- Fertilize your plants every two weeks during the growing season and once a month during the dormant season.
