Peat, Bark, Coir and Cocoa Shell


Soil in simple terms is a mixture of sand, clay and humus*.

When the balance of these three ingredients gets out of kilter we get problem soil
e.g. clay soil has too much clay, sandy soil has too much sand.

We can restore the balance by adding whatever ingredients are missing
e.g. add sand and/or humus to clay soil to restore the balance.

(*Humus is the organic content of soil and is derived from dead and rotting plant material)


Peat is the most widely used source of Humus in Gardening.
However it is to all intents and purposes a non-renewable material and we now need to preserve it by changing to peat alternatives.


Bark is the best alternative to Peat and as it is a waste product from forestry it is environmentally friendly.
Chipped Bark
is an ideal mulch and is more decorative than composted bark or peat.
Bark is in fact superior to peat in that it is slower to break down and so lasts about 3 times longer than peat.
Ground or Composted Bark is an ideal alternative to peat for digging into the soil to raise the humus level.

Cocoa Shell:

This was a popular mulch for a while but the cocoa tends to attract mice.


This was a popular mulch for a while but has lost popularity.
