ADVANCED Blueberry Substrates

The Ideal Symbiosis for Blueberries

Blueberries grow in natural symbiosis with mycorrhiza fungi and bacteria for improving the uptake of nutrients. Peat has been proved to significantly support this symbiosis. Our blueberry substrates therefore contain a higher proportion of quality sphagnum peat moss to allow best plant development and high yields.

Following comprehensive research, we have proved that substrates based on a combination of white sod peat and renewable GreenFibre® can lead to superior crop results compared with traditional mixtures consisting of one third each of milled peat, perlite and coir pith.

That is why we developed our ADVANCED Blueberry Substrates; well-balanced blends adjusted to any growing condition and with high long-term structural stability. The reduced amount of fine particles in the root zone leads to improved drainage and hence better root development.
ADVANCED Blueberry Substrates are supplemented with perlite or coco where even better drainage is required.


  • Characteristics: indoor and outdoor cultivation in containers up to 100 l. Also ideal for use with high EC irrigation water and in areas with heavy rainfall
  • Use for: blueberries

  • Characteristics: indoor and outdoor cultivation in containers up to 100 l. High structural stability with optimum water and air capacity
  • Use for: blueberries

“The use of GreenFibre®, perlite and coco fibre in our blueberry substrates leads to a very porous and open structure in the root zone. As a result, plants develop more roots due to better drainage even with heavy rainfall. Also in the long term there is no shrinkage, the root ball remains drier and does not tend to get muddy.”

Benefits of ADVANCED Blueberry Substrates

  • High porosity and stable structure for long-term cultivation
  • Increased and stable drainage
  • Balanced ratio between air and water capacity adapted to growing conditions
  • High water capacity for homogeneous moisture in the entire root zone
  • Use of GreenFibre®, perlite and coco fibre to improve drainage, air capacity and structural stability
  • Stable low pH value of 4.5 – 5.0 (H2O) and strong pH buffer due to use of sphagnum peat moss
  • GreenFibre® is a high quality, renewable wood fibre, leading to less substrate weight, increased truck loading volumes and a better carbon footprint
