I'm trying an experiment growing a plot in an area that was reclaimed by the DNR several years ago. The soil is mainly gravel beneath the thin top soil. The buckwheat was planted in May. Today we planted the soybeans. Check out the blog to see photos of the tall growth of buckwheat and the video.
Please comment on the height of the buckwheat. I have never seen it grow this tall and was rather surprised given the soil conditions.
