Brunnings Coir-Peat Brick 9L – Organic Soil Conditioner & Potting Mix Additive

Brunnings Coir-Peat Brick 9L

Brunnings Coir-Peat Brick is a compressed, lightweight growing medium made from natural coconut husk fibre. Once soaked in water, the compact brick expands to produce up to 9 litres of coir for improving garden soil, creating potting mixes and filling pots or hanging baskets.

Coir helps increase the amount of moisture soil can hold while maintaining a light, open texture around plant roots. When mixed through garden beds, it can also loosen hard clay soils and improve their structure over time. Brunnings states that it can remain in the soil for up to five years.

Why Use Coir Peat

Coir holds moisture while still allowing air into the growing mix, helping reduce the rapid drying and compaction that can occur in poor soil. This makes it useful in pots, vegetable patches, flower beds and homemade potting mixes.

It is a soil conditioner rather than a fertiliser, so it improves the physical structure of the growing medium but does not replace the nutrients plants need. For best results, combine it with quality soil, compost, fertiliser or other ingredients suited to the plants being grown.

How to Use

Place the coir brick inside a large bucket, tub or wheelbarrow before adding water.

• Add clean water gradually across the brick

• Allow time for the coir to absorb the water and expand

• Break apart any compressed sections by hand or with a garden tool

• Add more water if dry areas remain

• Allow excess water to drain if the coir becomes too wet

• Mix through soil or potting mix before planting

For garden beds, blend the expanded coir through the existing soil rather than leaving it as a thick layer on the surface. In pots or hanging baskets, combine it with suitable potting mix ingredients and plant nutrients.

Frequently Asked Questions

What is Brunnings Coir-Peat Brick made from?

It is made from natural coir obtained from coconut husk fibres. The material is dried and compressed into a compact brick for easier storage and transport.

How much does the coir brick expand?

One Brunnings Coir-Peat Brick expands to produce up to 9 litres of loose coir after it has absorbed water and been broken apart.

How do I use a coir peat brick?

Place the brick in a large container, add water gradually and wait for it to expand. Break apart the softened material, then mix it through garden soil, compost or potting mix.

Is coir peat the same as peat moss?

No. Coir is made from coconut husks, while traditional peat moss is harvested from peatlands. Both are used to improve moisture retention and texture in growing media.

Can I use Brunnings Coir-Peat in potting mix?

Yes. Brunnings recommends it as an additive when making potting mixes and preparing pots or hanging baskets. It should normally be combined with ingredients that provide nutrients and suitable drainage.

Does coir peat contain fertiliser?

No. Coir is primarily a soil conditioner and growing-medium ingredient. Add an appropriate fertiliser or nutrient source according to the needs of the plants being grown.

Is it suitable for clay soil?

Yes. Mixing expanded coir through hard clay soil can loosen its structure, improve aeration and increase its ability to hold moisture.

Can I use it in a worm farm?

Yes. Brunnings lists the coir brick as suitable for worm farm bedding. Hydrate it first and make sure the material is damp but not saturated before adding it.

How long does coir peat last in the soil?

Brunnings states that the coir can remain in the soil and continue improving its structure for up to five years.
