For the last 20 years, I have followed a tradition that I iniciated:
On New Year's Eve, after midnight, and of course after many celebratory beverages, I take my seeds from the refrigerator, and walk out in the snow, and cast the tiny seeds on the snow on a previously marked area.
The snow keeps the seeds from following blowing away with the wind.
This winter we did not have snow on New Year's Eve, however, I scattered some poppy seeds in February when we finally had some deep snow.
Many fellow gardeners are following my tradition.
