The Benefits of Coco Coir in Gardening: Things You Need to Know

There is a little-known fact that all parts of the coconut palm can be used to serve human life. From the trunk, leaves, fruit, and even roots all can be used to produce useful products. The coconut fruit, after providing sweet, cool water and a creamy coconut meat layer, also provides additional material for producing many versatile and effective coco coir products. Coco coir made from coconut husks can be used in handicrafts, wastewater treatment, or building materials. But coconut coir will fully realize its potential when used in agriculture.

The Benefits of Coco Coir

Take a look at some of the uses of coir in agriculture such as:

  • Versatile planting medium
  • Perfect covering layer for gardens
  • Ideal animal bedding
  • Essential material in soil mixtures

Thanks to numerous advantages, coconut coir is becoming increasingly popular and trusted among growers.

What is coco coir and how is it made?

Coco coir (also known as coconut fiber) is a natural growing medium produced from the coir layer between the outermost coconut shell and the inner hard coconut shell. When coconuts are harvested for their water and meat, the coconut shell is removed and the coconut husk is transported to a coconut coir production facility. The coconut husks after being processed and removed from unwanted objects becoming a material source with different shapes that creates ideal coco coir growing media for plants, including coco peat, coco fibers, and coco chips.

What is Coco Coir and How is it Made?

To produce coco coir, first, coconut husks are collected according to standard sizes, and removed from unwanted objects such as soil, stones, and garbage, etc. Then, the outer layer of the coconut is removed, and the coir husk part is soaked in water to soften it. The coconut fibers are softened and then further shredded and refined. Next, it is dried under sunlight or using a drying system before being ground to create a coco coir growing medium. Finally, it is packaged as loose-fill or compacted into blocks, depending on the intended use.

Benefits of coco coir

Here are some key features of coco coir:

  • High water holding capacity: Coco coir has an excellent water holding capacity, meaning it can retain a large amount of water while allowing for adequate drainage. This makes it ideal for plants that require consistent moisture, such as seedlings or plants grown in hot, dry climates.
  • Neutral pH: Coconut fiber has a neutral pH, which means it is neither acidic nor alkaline. This makes it a versatile growing medium that can be used for many types of plants without the risk of nutrient deficiency or toxicity.
  • Good nutrient retention: Coconut coir has a high cation exchange capacity, allowing it to hold the necessary levels of nutrients required by plants.
  • Sustainable and renewable: Coconut coir is a sustainable and renewable resource. It is an environmentally friendly alternative to non-renewable growing media such as peat moss.
  • High value: Previously considered a waste product of the coconut industry, coco coir has now become a valuable resource for agriculture in general, particularly in the field of horticulture.

Overall, the key features of coconut fiber make it a popular and versatile growing medium for both home gardeners and commercial growers. It is an ideal choice for many types of plants.

Key Features of Coco Coir

Different types of Coco Coir 

Material composition

  • Coco pith: Coconut husks after being ground will produce particles of small size and fine texture like sawdust or peat moss called coco peat. It has the most excellent hydration of the other components of the coconut shell, but it is more prone to drift. With a powder and porous texture, it is easy to squeeze into pellets (bricks) or make seeding cubes.
  • Coco fiber: Coco fiber is made up of small fibers that have a fairly strong and durable structure, allowing for easy oxygen penetration into the root system. It is also used as a component mixed with coco peat or various other growing media. Coco fiber is not only used as a planting medium but can also be used for weaving various handicraft products.
  • Coco chips: Coco chips consist of both small chunks and fibrous strings. They are the largest in size among all types of coco coir and are mainly used as ground cover material and growing media or mixed with other substrates. Coco chips have the ability to absorb water well and create air pockets that allow for easy water and nutrient circulation, preventing waterlogged conditions.

Different Types of Coco Coir

Types of Coco Coir

  • Buffered coco coir: Coco coir buffer is a type of coco coir that has been processed to adjust the pH level and remove any excess salt or minerals. The buffering process involves soaking the coco coir in a solution of magnesium and calcium or calcium nitrate to neutralize the pH level and remove any excess salt. This creates a more suitable environment for planting with a neutral pH level and reduces the risk of nutrient imbalance or toxicity.
  • Unbuffered unwashed coco coir: This is a type of raw coco coir that is not recommended for agricultural use because of its high salt content, low pH level, and potential to contain natural pollutants. These are factors that directly affect the growth of plants.
  • Washed coco coir: Cleaned coconut fiber is a type of coconut fiber that has been rinsed and thoroughly washed to remove any unwanted ingredients before being used as a planting medium. Cleaned coco coir has loosened fibers, making it more fluffy and easier to use as a planting medium.

Advantages of gardening with coco Ccoir

There are several advantages to gardening with coco coir including:

  • Sustainability: Coco coir is a renewable resource made from the byproduct of the coconut harvesting process, making it an environmentally friendly substitute for traditional soil or peat moss.
  • Water retention: Coco coir has excellent water holding capacity, allowing plants to retain moisture and reducing the frequency of watering.
  • pH balance: Coco coir has a neutral pH level, making it a more flexible planting medium that can easily be adjusted to suit the needs of different plants.
  • Aeration: Coco coir is highly porous and allows for ample airflow to the plant’s roots, helping to prevent waterlogging and root rot.
  • Nutrient retention: Coco coir can retain nutrients and release them slowly over time, providing a stable source of essential nutrients for the plants.
  • Sterility: Coco coir is naturally sterile, making it less likely to harbor harmful bacteria or plant pathogens that can affect plant health.
  • Versatility: Coco coir can be used alone as a planting medium or mixed with other substrates to create customized blends for different plants and gardening applications.

Advantages of Gardening with Coco Coir

All of these benefits make coco coir a popular choice for indoor and outdoor gardening, particularly in large and small hydroponic systems.

How to choose high quality and proper coco coir

Choosing high-quality and appropriate coco coir is very important to ensure the health and growth of your plants. Here are some tips on how to choose the best coco coir:

  • Check the source: Look for coco coir from a reputable source. Coco coir should be produced from dry coconut husks that meet standards, extracted and processed without harmful chemicals.
  • Check the moisture content: Avoid coco coir that is too wet or too dry, as this can indicate poor quality or improper storage. Too much moisture can lead to mold or other plant diseases, while too little moisture can make the coco coir brittle and difficult to work with.
  • Check for impurities: Coco coir should not have impurities like sand, stones, or other debris. Look for coconut fiber that has been properly filtered and screened to remove these impurities.
  • Check the pH level: Coconut fiber should have a neutral pH level between 5.5 and 7.0. This ensures that it will not alter the pH balance of the soil or affect the plant’s nutrient uptake.
  • Consider the type of coconut fiber: There are different types of coconut fiber, including coconut peat, coir, and fiber. Each type has unique characteristics and can be used in different ways. Consider the type of plant you want to grow and choose the appropriate type of coconut fiber.

By following these tips, it will make it easier for you to choose high-quality and appropriate coconut coir products. Choosing the right type of coconut fiber for your needs and each type of plant is a key factor in promoting healthy plant growth and helping you achieve successful gardening results.
