New information leaflet on bark products bearing the RAL quality mark
Bark products bearing the RAL quality mark ‘Substrates for Plants’ are characterised by their exceptionally high quality, which is continuously monitored by the RAL Quality Association for Substrates for Plants (GGS). A new leaflet explains to consumers, users and retailers which material properties are tested and provides specific recommendations for the use of these bark products.
Information leaflet on using peat-free growing media
This publication is aimed directly at consumers and explains, in clear and accessible language, the adjustments to watering, fertilising, repotting and storage that are required due to the specific characteristics of peat-free or low-peat growing media.
Keeping hydrangeas blue – a question of soil
Blue hydrangeas require some gardening knowledge. We explain how the blue colour comes into bloom and how it can be preserved in the long term.
Refilling raised garden beds
It is especially important not to save on the wrong end when refilling raised garden beds: The quality of the filling is decisive for the success!
Improving soil with bark humus
Bark humus increases the percentage of organic matter in soil and consequently will improve supply of water, air and heat to the soil. This will enhance soil fertility and make the soil easier to handle. The plants will perform better, produce higher yields and are generally in better health.
