I plant buckwheat in all the harvested areas of the garden as a green manure cover crop. I have done that for several years now. I notice that the height is not uniform, in one well manured area it grew fairly tall, then the wind blew it over and it lay flat and then sort of grew tops that reached up to bloom, but the plant could not lift itself up. It provided very good living mulch, killed most weeds and kept the soil moist. I was thinking of letting the
chickens in and
feed themselves off the seeds. I had three patches this year, two grew big and one did not. I noticed
bees in the flowers. Harvesting the seeds does not look very encouraging.
