Coir Bricks – how to use

Posted on

You can use coir bricks for seed raising or cuttings. Coir makes a perfect base for homemade composts. You can also aerate garden waste compost with it.

How much coir does one brick hold?

A Fertile Fibre compressed coir brick (0.625 kg) — the size of a house-brick — will expand to make approximately 9 litres of fibre.

Just soak overnight, and it is ready for use.

What’s the best fertilizer?

Straight coir contains only low amounts of plant nutrition but can be used for seeds and cuttings as long as they are potted up once established.

NuGro is a perfect balanced plant food for using with coir block, especially as an initial plant food and for subsequent feedings. NuGro is very easy to use. Just add 24ml in 3 litres of water per brick.

The compost from your coir brick can now be added to your own compost mixes. Or you can add well-rotted manure, green waste, bark, sand, or grit to it for your perfect mix. Potting compost will be produced by adding our specially formulated plant food or 5Fs fertilizer.
