Rehydrating Coconut Coir Bricks
What is Coconut Coir?
Coconut coir is a natural fibre extracted from the husk of coconuts, commonly used as a growing medium in gardening and horticulture. Rehydrating coconut coir is essential to unlock its full potential as an eco-friendly, sustainable alternative to peat moss, offering excellent water retention, aeration, and a neutral pH, making it suitable for a wide range of plants. Coconut coir can be used in hydroponics, seed starting, potting mixes, and as a soil amendment, promoting healthy root growth and reducing the need for frequent watering.
Benefits of using Coconut Coir

- Biodegradable and reusable – Once you have used coconut coir, place it on the compost heap or reuse it elsewhere in the garden.
- Great water retention – Coconut coir can retain water exceptionally well, reducing the required watering frequency.
- Improves Soil Aeration – A fibrous structure allows for good air circulation around plant roots, promoting healthy and vigorous root growth and development.
- pH Neutral – A near-neutral pH makes this growing medium suitable for a wide range of plants.
- Resistant to Pests and Diseases – Coconut Coir is naturally resistant to common pests and diseases found in soil, enhancing plant health.
- Odourless – Unlike other growing mediums which can carry a strong odour, Coconut Coir is odourless making it suitable for use in the home.
Rehydrating Coconut Coir Bricks
Coconut coir is often sold in compressed blocks for several practical reasons, including space efficiency, ease of handling, and extended shelf life. Before using coconut coir, you will need to rehydrate and expand the block to make it usable as a growing medium
1. Remove any packaging from the brick and place it into a bucket. Ensure that the bucket is large enough to accommodate the fully expanded brick. This can be many times its compacted size! For example, a 650g brick will expand to fill approximately 10 litres.
2. Add lukewarm water to the bucket, ensuring the brick is covered as much as possible. A 650g brick will require approximately 3 litres.
3. Leave for 10 – 20 minutes to allow all the water to be absorbed.
4. Break up and aerate the coir. If you find any dry pieces add a little more water.
In summary, coconut coir is an excellent eco-friendly alternative to traditional growing mediums like peat moss. Its benefits include superior water retention, improved aeration, a neutral pH, and natural resistance to pests and diseases, making it ideal for a variety of gardening uses. Additionally, coconut coir is biodegradable and reusable, further enhancing its sustainability. Whether you’re using it for seed starting, or as a soil amendment, rehydrating coir bricks is a simple process that transforms this compact product into a highly effective tool for promoting healthy plant growth. I tend to store my rehydrated coir in a bucket until it’s ready for use, ensuring it’s always on hand when needed.
