Mow the meadow or field in late summer, before planting. Rake to remove dead grass and debris that cover the soil.
Broadcast wildflower seeds after the soil temperature has dropped to 40 degrees Fahrenheit or less and will remain that cold until springtime. The seeds will remain dormant until warmed by spring rains and milder days.
Scatter seeds while it is raining or snowing. Snow will cover the seeds and protect them from foraging birds and help keep them in contact with the soil.
