Buckwheat is an annual that grows very quickly. It should be sown between April and June. It is not frost hardy but is good at scavenging phosphate from the soil. It is a weed supressor, but not a nitrgoen fixer.
If sowing as a straight, sow at 125kg/ha. or 50kg/ac. If adding to a mixture, a lower rate may be applicable – please contact us for more information if you are unsure or have any other questions.
