Ich habe den Buchweizen als Gründüngung ausgesät, vor allem in den sonnigen Morgenstunden eine tolle Bienenweide. Er steht nicht sehr dicht, ich hoffe er schützt das Beet als lebende Mulch-Schicht im Winter ausreichend. Im Frühjahr werde ich ihn als Gründüngung abschneiden und evtl. einarbeiten oder einfach nur als Mulch obenauf liegen lassen.
