Raw materials

The raw materials which we use are characterised by different air and water proportions which enables us to manufacture the perfect substrate for every plant. 

The most important raw materials of the HAWITA Group are black and white peat from North Germany and the Baltic region. We currently extract this basic material which is so important for plants on an area of more than 4,500 hectares and will continue to do so for the coming decades.

We also have our own clay deposits in the Vogelsbergkreis in Hesse. Volcanic clay has a stable crumb, provides a constant supply of trace elements and gives the cultivation substrate the necessary heaviness. This is why the clay for the well-known Fruhstorfer mixture is intensively mixed with peat, is absorbed and combines to form a stable clay-humus compound.

We have also been increasingly using alternative substrate source materials for years. Green compost and bark humus are used as well as wood and coconut fibres. We are in close association with research institutes and are permanently testing further alternative substrate source materials to save the precious raw material peat. 

Peat remains irreplaceable

Despite all the substitute materials, peat remains indispensable for professional horticulture. This is largely due to its properties which are not offered in this form by any other aggregate.

As peat is formed out of the decomposition process of peat mosses with the absence of air, its quality hardly fluctuates. Professional gardeners always receive consistently high quality substrates and, with this, maximum assurance for plant growth. The low pH value and longevity are further factors which make peat irreplaceable.
