I have about 2 acres ready to sow Buckwheat and with rain forecast for late Friday and into Saturday, I hope to get it done before then. An older beekeeper told me that the buckwheat would bloom within 4 weeks of breaking the ground and bloom for 2 weeks. He said to wait until all the blooms are gone and then to mow it down and let it reseed itself. He said that would allow the process to start over and with luck and proper rainfall, give me 3 maybe 4 blooming seasons before frost. Anyone have any experience with Buckwheat?
