In December we have already started pre-treating most species for the new season. In short, this means that the seeds receive cold treatment. The reason for this is that we are basically mimicking nature and eliminating the ‘weak’ least promising seeds. In general, this is done by mixing the seeds with sand and storing them outdoors or in the refrigerator. Depending on the species, this period lasts from 4 to 8 weeks. In the photo you can see what that looks like.
