It takes 15 years of research and development for a Full traceability: the green label on our lawn seed bags tells new variety to make it into a Johnsons Sports Seed bag where the seed is produced and that it is tested and certified. Year 1-3 Different grasses are crossed in order to find new and improved varieties The new varieties are propagated and sown in thousands of test plots. Year 4-8 The new breeding lines are tested. Only the best varieties continue in our breeding program. Year 9-10 Every year we test new varieties under different climatic conditions to evaluate their performance. The very best varieties are chosen for further official trials e.g. STRI. Year 11-14 The chosen varieties are tested and evaluated in trials by official independent authorities. The highest performing varieties are put into initial production with our experienced seed growers. Year 14 Official trials are completed. Only the varieties that have passed the official tests appear on the lists of recommended varieties (e.g. STRI, STERF). Year 15 Certified seeds are harvested, cleaned and samples are taken and tested for purity and germination in our own laboratories. Year 15+ After careful selection the varieties are mixed and packed into our famous black bags at our dedicated amenity warehouse. 04 Crossing of grasses The new varieties are evaluated several times a year Our field inspectors inspect the fields several times a year DLF’s 30 analysists in three ISTA* accredited laboratories in Denmark and Holland ensure that our seed live up to national and international standards *International Seed Testing Association.
