When to Plant Cilantro in California: A Regional Guide
When you plant cilantro in California, you need to consider the microclimate you’re gardening in.
The state spans from USDA zones 5 to 11, so planting times shift depending on where you live.
1. Coastal California
In coastal areas like San Francisco, Santa Monica, or San Diego, the mild ocean influence makes planting cilantro a year-round possibility.
The best time to plant cilantro in California’s coastal regions is early spring (March to April) and again in late summer (August to September).
Summers are cool enough that cilantro won’t bolt immediately, giving you a longer harvest window.
2. Inland Valleys and Central California
If you’re in the Central Valley or inland areas like Sacramento or Fresno, planting cilantro in California means avoiding the scorching summers.
Plant cilantro in late February to early April, or wait until September through October for a fall crop.
Summer heat will cause cilantro to bolt and go to seed almost overnight.
3. Southern California Deserts and Hot Inland Areas
In places like Palm Springs or the Mojave Desert, when to plant cilantro in California shifts dramatically.
The ideal planting window is October through February when temperatures are cooler.
Planting cilantro in California’s desert regions during spring or summer is a recipe for instant bolting.
4. Mountain Regions
In higher elevations like the Sierra Nevada, plant cilantro from late spring (May to June) once the danger of frost has passed.
You can also plant cilantro in California’s mountain areas in early fall for a quick crop before the first freeze.
Tips for Growing Cilantro in California
Once you know when to plant cilantro in California, a few smart practices will keep it thriving.
1. Succession Planting
Because cilantro bolts fast, plant small batches every 2-3 weeks.
This ensures a continuous supply of fresh leaves.
When you plant cilantro in California this way, you’ll always have tender sprigs ready for salsa or guacamole.
2. Choose Bolt-Resistant Varieties
Varieties like ‘Slow Bolt’ or ‘Calypso’ are great choices for California gardens.
They tolerate heat a bit better, giving you more time to harvest.
3. Provide Afternoon Shade
In hotter parts of California, plant cilantro where it gets morning sun and afternoon shade.
This simple trick can extend your harvest by weeks.
4. Keep the Soil Moist
Cilantro prefers consistently moist soil.
Dry conditions stress the plant and speed up bolting.
Water regularly, especially in California’s dry climate.
5. Harvest Often
Frequent harvesting encourages new growth and delays flowering.
Snip outer leaves first and let the inner ones mature.
Common Mistakes When Planting Cilantro in California
Even seasoned gardeners make mistakes with cilantro.
Here are a few to avoid.
1. Planting in Peak Summer Heat
This is the biggest mistake.
Cilantro hates heat, so planting cilantro in California during July or August usually fails.
2. Overwatering or Poor Drainage
While cilantro likes moisture, soggy roots lead to rot.
Make sure your soil drains well.
3. Ignoring Your Local Microclimate
California’s weather varies wildly.
What works in Eureka won’t work in Bakersfield.
Always check your local extension office for the best planting dates.
So, When to Plant Cilantro in California?
When to plant cilantro in California comes down to avoiding extreme heat and timing your crop for mild temperatures.
