Seeds of Change finally got my order of organic Buckwheat to me. According to the package, it will produce flowers in 5 to 6 weeks and grow 3 to 6 feet tall. It will smother weeds. When cut for green mulch it will turn into a weed free, mellow and loose seedbed for other plants. Hence why I used this in the vegetable garden in the empty beds for fall.
Again, according to Seeds of Change, it will attract numerous beneficial insects, and make phosphorus, calcium, and potassium readily available as it decomposes as green mulch, so for me it is win win.
This got sown this morning after anti-slug patrol. The 3 Sisters garden bed was also planted with more scarlet runner beans and corn.
