Warm season crop for building soil and smothering weeds.
Planting several successions in a season can be effective for eradicating persistent annual weeds which are out-competed by buckwheat's quick growth. Loosens clay, increases phosphorus and holds fertility for the next crop. Plant once soil has warmed. Seeding rate: 35-135 lbs/acre, 2-3 lbs/1000 sq ft.
