There are many different peat alternatives with this series I am starting with coir or coco peat.
- Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut.
- Coir is mainly produced in India and Sri Lanka
- But before the horticultural industry got hold of it sailors used it as ships ropes.
Coir is mainly imported from Sri Lanka as coir is a waste product and transported to the UK. Coir has a good mix of medium, fine and coarse fibres which makes a good growing media. As a negative of coir is that it does not have good nutrients holding capabilities and as such can be hungry.
As with peat-based compost, a wetting agent is added to retain water. Coir does have a tendency for the surface of the compost to dry out, whereas below the surface the compost is sufficiently moist, so it is easy to overwater.
