Buckwheat should be planted from late June to Mid-July to give a seed or cover crop. Sown during this time, it will normally flower in the cool temperatures of September; earlier plantings risk flowering during hot weather which reduces bee travel and pollination. It is well adapted to poor soils and will lodge on highly fertile soils. The best time to till buckwheat into the soils is when it blooms; however, the bees should be allowed to work the white blossoms for a few days. Combine harvesting must be done as soon as most of the grain is ripe, but before significant shattering occurs. Common buckwheat is a mixture of types generally well adapted to northeastern conditions.
