| I don't think you need to stomp the seeds down. If you mowed the plants down in winter, then the natural action of snow, freeze, thaw and rain should have worked the seed down to the soil. (That's how mother nature does it.) How well annuals resow is highly variable, depending upon weather conditions from when the seeds were formed to when the seeds were germinating... I probably would do a wait and observe...mainly because I am cheap and lazy. If I didn't get as much resowing this year as I would have liked, then I would resow next year. If there were some critical event that I wanted to have a grand display for this year, I would resow this year... |
