How To Keep Cilantro Growing All Summer

You can keep cilantro growing all summer by choosing slow-bolting varieties, providing afternoon shade, and harvesting regularly.
 
Cilantro is one of those herbs that loves cool weather, so when summer heat rolls in, it tends to bolt and go to seed fast.
 
If you’ve been wondering how to keep cilantro growing all summer without it turning into a flower stalk overnight, you’re in the right place.
 
The good news is that keeping cilantro growing all summer is absolutely possible with a few smart tricks.
 
In this post, we’ll walk through how to keep cilantro growing all summer long, from picking the right type to shady planting spots and steady snipping.
 
Let’s dive in.
 

Why Cilantro Bolts in Summer Heat

Cilantro bolts when temperatures climb, and understanding why helps you keep cilantro growing all summer.
 

1. Cilantro Is a Cool-Season Herb

Cilantro naturally thrives in spring and fall when the air is mild.
 
Once the mercury pushes past 75°F, cilantro starts feeling stressed.
 
That stress signals the plant to reproduce quickly by sending up a flower stalk.
 
This is why keeping cilantro growing all summer feels like a race against the sun.
 

2. Bolting Is a Survival Tactic

When cilantro bolts, it’s basically panicking.
 
The plant thinks its time is up, so it rushes to produce seeds before it dies.
 
Those seeds are coriander, which is nice for your spice rack but bad for your salsa.
 
The key to keeping cilantro growing all summer is slowing that panic response down.
 

3. Long Daylight Hours Trigger Flowering

Cilantro is sensitive to day length, and long summer days tell it to bolt.
 
Combined with heat, this double whammy makes summer the hardest season for cilantro.
 
So how do you keep cilantro growing all summer despite all this?
 
You work with the plant instead of against it.
 

How to Keep Cilantro Growing All Summer

Keeping cilantro growing all summer comes down to three big moves: shade, variety, and timing.
 

1. Pick Slow-Bolting Cilantro Varieties

Some cilantro types are bred to resist bolting longer than others.
 
Look for names like ‘Slow Bolt,’ ‘Calypso,’ or ‘Santo.’
 
These varieties give you a fighting chance at keeping cilantro growing all summer.
 
Planting these instead of standard cilantro can buy you weeks of extra harvest.
 

2. Give Cilantro Afternoon Shade

Cilantro loves morning sun but hates the blazing afternoon heat.
 
Plant it where it gets shade from about noon onward.
 
A spot near a taller plant, a fence, or a shade cloth works wonders.
 
This simple step is huge for keeping cilantro growing all summer without bolting.
 

3. Water Consistently and Mulch

Dry soil stresses cilantro and speeds up bolting.
 
Keep the soil evenly moist, but never soggy.
 
Add a layer of mulch to cool the roots and hold moisture in.
 
Consistent watering is one of the easiest ways to keep cilantro growing all summer.
 

4. Harvest Often and Early

The more you snip, the more the plant focuses on leaves instead of flowers.
 
Start harvesting when the plant is about six inches tall.
 
Take the outer stems first and leave the inner ones to keep growing.
 
Regular cutting is a simple but powerful trick for keeping cilantro growing all summer.
 

5. Sow Successively Every Few Weeks

Even the best cilantro will eventually bolt, so don’t rely on one planting.
 
Sow new seeds every two to three weeks through early summer.
 
That way, when one patch gives up, another is ready to take over.
 
Succession planting keeps cilantro growing all summer without a gap in your harvest.
 

Extra Tips to Keep Cilantro Growing All Summer

A few bonus habits make keeping cilantro growing all summer even easier.
 

1. Snip Off Flower Stalks Fast

If you spot a flower stalk forming, pinch it off right away.
 
This delays bolting and pushes energy back into leaf growth.
 
It’s a quick fix that helps keep cilantro growing all summer a little longer.
 

2. Grow Cilantro in Containers

Pots let you move cilantro to cooler spots as the season heats up.
 
You can shift containers to a shaded patio or indoors during heat waves.
 
This flexibility is a big win for keeping cilantro growing all summer.
 

3. Use Shade Cloth During Heat Waves

When temps spike above 85°F, throw up a shade cloth.
 
Even 30% shade can drop leaf temperatures enough to slow bolting.
 
It’s a cheap tool that helps you keep cilantro growing all summer.
 

4. Feed Lightly, Not Heavily

Too much nitrogen makes cilantro grow fast and bolt sooner.
 
Use a diluted liquid fertilizer every few weeks instead.
 
Balanced feeding supports steady growth and helps keep cilantro growing all summer.
 

So, How to Keep Cilantro Growing All Summer?

You can keep cilantro growing all summer by choosing slow-bolting varieties, planting in afternoon shade, watering consistently, and harvesting often.
 
Cilantro bolts in summer heat because it’s a cool-season herb that panics when temperatures rise.
 
But by working with its nature instead of fighting it, you can enjoy fresh cilantro for months.
 
Use succession planting, shade cloth, and containers to stretch your harvest even further.
 
With these tips, keeping cilantro growing all summer becomes a simple routine rather than a struggle.
 
So go ahead and give these tricks a try, and you’ll have fresh cilantro all season long.
