How To Grow Cilantro In California

You can grow cilantro in California almost year-round if you time your planting around the heat.
 
California’s diverse climate means growing cilantro here depends a lot on where you live.
 
Coastal gardeners can grow cilantro in California with much more forgiveness than those inland.
 
If you’ve ever watched your cilantro bolt in what felt like five minutes, you’re not alone.
 
In this post, we’ll walk through how to grow cilantro in California, from timing and location to the tricks that keep those leaves coming.
 
Let’s dig in.
 

How to Grow Cilantro in California

Growing cilantro in California is totally doable, and the key is understanding what this cool-season herb actually wants.
 
Cilantro loves mild temperatures, somewhere between 50°F and 85°F, which is why California’s spring and fall are its sweet spots.
 
When you grow cilantro in California, you’re basically racing against the heat.
 
Once daytime temps push past 85°F, cilantro bolts, sending up a flower stalk and turning its leaves bitter.
 
But here’s the good news: that bolting is exactly what gives you coriander seeds later.
 
So how you grow cilantro in California really depends on whether you want leaves or seeds.
 
Here’s what makes it work:
 

1. Timing Is Everything

The best time to grow cilantro in California is early spring and again in late summer for a fall harvest.
 
Along the coast, you can practically grow cilantro in California all year long because the ocean keeps things cool.
 
Inland and in the Central Valley, you’ll want to plant in February or March and then again in September.
 
If you’re in Southern California’s hotter zones, fall planting is your best friend.
 

2. Pick the Right Spot

Cilantro does best in partial shade when you grow it in California’s sunnier regions.
 
Full sun is fine in coastal areas, but inland gardeners should aim for morning sun and afternoon shade.
 
A spot that gets four to six hours of light is usually perfect.
 
Too much intense afternoon sun is what pushes cilantro to bolt prematurely.
 

3. Soil and Water Needs

Cilantro likes loose, well-draining soil that stays consistently moist.
 
When you grow cilantro in California, amend your soil with compost so it holds moisture without getting waterlogged.
 
Water regularly, but let the top inch of soil dry out between waterings.
 
Mulching around your plants helps keep the roots cool, which slows bolting.
 

Tips for Growing Cilantro in California

Once you’ve got the basics down, a few smart habits will keep your cilantro productive for longer.
 
These tips make growing cilantro in California a lot less frustrating:
 

1. Sow Seeds Directly and Often

Cilantro hates being transplanted because of its long taproot.
 
So when you grow cilantro in California, always sow seeds straight into the garden.
 
Plant a small patch every two to three weeks for a continuous supply.
 
This succession planting means when one batch bolts, the next is ready to go.
 

2. Harvest Frequently

The more you snip, the more cilantro produces before it bolts.
 
Start harvesting outer leaves once plants are about six inches tall.
 
Regular cutting signals the plant to keep making foliage instead of flowers.
 

3. Choose Slow-Bolting Varieties

Some cultivars are bred to resist bolting, which is huge when you grow cilantro in California.
 
Look for “Slow Bolt,” “Leisure,” or “Santo” at your local nursery or online.
 
These varieties give you a longer window to harvest fresh leaves.
 

4. Manage the Heat

Shade cloth and afternoon shade are your best tools during hot spells.
 
You can also grow cilantro in California in containers so you can move them out of the midday sun.
 
Keeping the soil cool with mulch and consistent watering helps too.
 

Common Problems When You Grow Cilantro in California

Even with the best care, a few issues pop up when growing cilantro in California.
 
Knowing them ahead of time saves you a lot of heartache:
 

1. Bolting

Bolting is the number one complaint for anyone who grows cilantro in California.
 
It happens when the plant gets stressed by heat or a sudden temperature swing.
 
You can’t stop it entirely, but shade, cool soil, and succession planting soften the blow.
 

2. Wilting in the Afternoon

Cilantro often wilts during the hottest part of the day, then perks back up at night.
 
This is normal, but if it stays droopy, you’re probably underwatering.
 
Check the soil before you reach for the hose.
 

3. Aphids and Powdery Mildew

Aphids love tender cilantro leaves, so spray them off with water or use insecticidal soap.
 
Powdery mildew shows up in humid, crowded conditions.
 
Space your plants and water at the base to keep the leaves dry.
 

So, How Do You Grow Cilantro in California?

You can grow cilantro in California by planting in the right season, choosing a spot with afternoon shade, and harvesting often to delay bolting.
 
Coastal gardeners have it easier, but inland growers can absolutely succeed with fall planting and succession sowing.
 
Grow cilantro in California in small batches, keep the soil cool and moist, and you’ll have fresh leaves for months.
 
And when it finally bolts, let it flower and collect the coriander seeds.
 
Either way, you win.
