When to plant garlic in California

California spans USDA hardiness zones 5a-11. Average last spring frost: varies by region. This calendar gives you the indoor start, transplant, and direct-sow dates for Allium sativum.

California planting dates for garlic

Dates for California vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: direct sow 24 weeks after last frost.

Why these dates

Garlic is fall-planted. Plant cloves 4-6 weeks before the ground freezes (October-November in most zones). Harvest the following July when the bottom 3-4 leaves brown.

The dates above are anchored to California's average last spring frost date (which varies by region within the state), with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
