It’s good to use a net of grass and stalk. No further action required!
If you have no net and the ground is dry and as smooth as water and any old seed will just skitter over it in the wind like a figure skater, no problem. Dry it out. It’ll crack like an old pot.
Once the seeds have caught in the cracks, nicely spaced by the intersections between the wind and the angles of breakage, water will get them going.
The trick is not to wait until May. This technique works for a spring in November.
