This is normally grown as a green manure and dug in before it flowers. That much I know. We also eat the grains, both as flour and whole. First time we have seen seed on sale, but we were wondering if we grow it and allow it to flower and then harvest the seeds are we letting ourselves in for trouble with a persistent self seeding weed?
I don't know why it's never grown as a crop here, seems it's not difficult. Will you reort back how you get on? www.motherearthnews.com/Organic...05.../Buckwheat.aspx This gives some very useful info, you might have to cut & paste, can't do a link!
