Coir is ideal for seeds and cuttings. It can be used as a base for homemade composts or added to aerate garden waste composts. Coir is known by many different names including coco, coco coir, cocopeat, coco peat, coir fibre, coconut husks and coconut fibre.

Each brick is about the same size of a house brick. The compressed coir will expand to three times its size when rehydrated with water. It makes approximately 9 litres of coir.


Coir can be used for seeds and cuttings as long as they are potted up once established or provided with extra nutrients. Coir is a naturally inert material so perfect as a base to build on. Check out our recipes in our fertiliser section to add the correct levels of nutrients or experiment mixing our coir with your own homemade compost.

Use approx 3 litres of water per brick to rehydrate.


  • You will need a large bucket/bowl or preferably a watertight wheelbarrow.
  • Add 3 litres of water (warm water acts faster) per brick.
  • Leave to stand for 24 hours. This will even out the water content of your finished material.
  • You will find the bricks will expand to as much as three times their original size.
  • Break up the material with either a small spade or fork or by hand
