Root Vegetable

When to Plant Beets in California

Two crops in one — eat the roots and the greens. Beets are cold-hardy and surprisingly easy.

The Short Answer

California grows beautiful beets year-round in coastal areas and during the cool season inland. The crop's tolerance of moderate temperatures and its fast maturity make it one of the most practical root vegetables for California home gardens.

Growing Beets in California

State-Specific Growing Tips

Coastal: grow year-round. Central Valley: sow September through March. Inland Southern California: October through March. Mountain: spring and fall. California's dry climate reduces foliar disease pressure. Beets grow well in a range of soil types. Drip irrigation maintains consistent moisture.

Recommended Varieties for California

Everything grows in California. Detroit Dark Red, Chioggia, Golden, and specialty varieties like Badger Flame. Farmers market growers favor colorful varieties for visual appeal. UC Master Gardener trials include beet data.

Common Challenges in California

Cercospora leaf spot in coastal fog. Aphids. In the Central Valley, summer heat above 85°F causes tough, woody roots — don't attempt summer beets inland.

Growing Tips

Each beet 'seed' is actually a cluster — thin to one plant after sprouting. Harvest at 1.5-3 inches for tender roots.

Companion Planting

Plant beets alongside these companions for better growth:

Onions Lettuce Cabbage Broccoli

Keep beets away from:

Pole Beans

The Bottom Line

Beets can be grown successfully in California with proper attention to regional frost dates and local growing conditions. Timing varies across the state — Northern California Mountains gardeners work with a last frost around May 1 - May 25, while Bay Area sees frost end around Jan 20 - Feb 15. Choose varieties suited to your region, amend your soil based on its specific needs, and monitor for the pests and diseases most common in your area.
