Buckwheat planting in California.
Buckwheat planting in California is shaped by the state's 9a dominant hardiness zone, last frost date around March 1, and a 270-day growing season. Buckwheat can be grown in California with attention to season length and variety selection — primarily a specialty or experimental crop here.
Planting dates on this page are climatological estimates from USDA frost-date norms and zone-typical planting offsets. Verify against University of California Cooperative Extension for variety- and county-specific guidance.

Growing notes
Buckwheat is challenging in California's climate — focus on short-season varieties, raised beds, season extension (row cover, low tunnel), or microclimates with longer growing windows.

Agronomy reference
Short-season warm-weather cover crop — frost-sensitive, but matures fast enough to fit summer planting windows after winter wheat harvest.

Variety selection
Buckwheat varieties for California live with your extension service.
Variety performance is micro-regional and changes with each year’s trial cycle. We don’t republish variety lists — instead, we point directly at the source.
Search the extension site for “buckwheatvariety trial” or “recommended buckwheat varieties” to find the current report.
Yield varies significantly by variety, soil, fertility, and management. Consult your state extension service for variety performance trials in your region.
Beyond the harvest
Buckwheat as a hunting food plot.
Buckwheat is a top dove-hunting cover crop — flowers attract pollinators all summer, then seed-out in late summer brings doves to the field. Time planting 70-80 days before opening day of dove season.
Buckwheat and your farm pond.
Buckwheat flowers attract pollinators which support insect populations that feed bass fingerlings and bluegill in your farm pond.
