Only the higherst performance cultivars are selected for the Johnsons sports seed range following independent testing across europe.
Johnsons cultivars have been tested under a wide range of climatic and growth conditions in order to ensure optimal performance under the tough conditions they will be exposed to.
Different grasses are crossed in order to find new and improved varieties. The new variesties are propagated and sown in thousands of test plots.
The new breeding lines are tested. Only the best varieties continue in our breeding program.
Every year we test new varieties under different climatic conditions to evaluate thier performance. The very best variesties are hosen for further offical trials e.g STRI.
The chosen variesties are tested and evaluated in trials by official independent authorities. The highest performing varieties are put into production with our experienced seed growers.
Official trials are completed. Only the varieties that have passed the official tests appear on the lists of recommended varieties. (e.g. STRI, SERF).
Certified seeds are harvested., cleaned and samples are taken for purity and germination in our own laboratories.
After careful selection the varieties are mixed and packed into our famous black bags at our dedicated amenity warehouse.
