Can Cilantro Grow In Cold Weather

Cilantro can grow in cold weather, but how well it does depends on how cold it gets and how you protect it.
 
Cilantro is actually a cool-season herb that prefers milder temperatures over scorching summer heat.
 
In fact, cilantro grows best when the weather is between 50°F and 85°F, which means it often thrives in spring and fall.
 
So if you’re asking can cilantro grow in cold weather, the short answer is yes, but there are limits.
 
Once temperatures drop below freezing for extended periods, cilantro will struggle unless you give it some protection.
 
In this post, we’ll look at how cold cilantro can tolerate, ways to keep it growing through chilly spells, and tips to stretch your harvest.
 
Let’s dig in.
 

Can Cilantro Grow in Cold Weather?

Yes, cilantro can grow in cold weather, and it actually prefers cooler conditions over intense heat.
 
The key is understanding exactly how cold is too cold for this leafy herb.
 
Cilantro is hardy in USDA zones 3 through 11, which tells you it can handle a fair amount of chill.
 
Here’s what happens at different temperature ranges:
 

1. Mild Cold (50°F to 60°F)

Cilantro grows in cold weather like this beautifully.
 
Temperatures in the 50s keep the plant lush and slow its tendency to bolt, which is when it shoots up a flower stalk and turns bitter.
 
This range is ideal if you want to harvest tender leaves for weeks.
 

2. Light Frost (28°F to 32°F)

Cilantro can survive a light frost, though the outer leaves may get nipped.
 
The plant’s root system stays alive, and new growth often appears once the weather warms slightly.
 
A row cover or a thick layer of mulch can help cilantro grow in cold weather like this without too much damage.
 

3. Hard Freeze (Below 25°F)

When the mercury plunges below 25°F, cilantro growing in cold weather starts to suffer.
 
The leaves will freeze, turn mushy, and die back.
 
However, if the roots are well-mulched, the plant may regrow in spring.
 
So technically, cilantro can grow in cold weather down to a point, but a hard freeze usually ends the leaf harvest.
 

How to Help Cilantro Grow in Cold Weather

If you want cilantro to grow in cold weather, a little intervention goes a long way.
 
Here are the most effective strategies:
 

1. Use Row Covers or Cloches

Floating row covers and cloches trap heat and block wind, which helps cilantro grow in cold weather even when nights dip near freezing.
 
You can drape fabric directly over the plants or use glass jars for small patches.
 
This simple step can keep cilantro growing in cold weather for several extra weeks.
 

2. Mulch Heavily

A thick layer of straw, leaves, or compost around the base insulates the soil.
 
This protects the roots so cilantro can grow in cold weather without the ground freezing solid.
 
Mulch also locks in moisture, which is another plus.
 

3. Choose a Sheltered Spot

Plant cilantro near a south-facing wall or in a raised bed that gets full sun.
 
These spots stay warmer, making it easier for cilantro to grow in cold weather.
 
Windbreaks like fences or hedges also reduce chill damage.
 

4. Water Sparingly

Wet soil freezes faster and harder than dry soil.
 
So when you’re trying to get cilantro to grow in cold weather, water only when the soil is dry to the touch.
 
Morning watering is best because it lets excess moisture evaporate before nightfall.
 

Cold Weather and Bolting: What to Expect

One quirk of cilantro is that cold weather can actually delay bolting.
 
That’s good news if you want leaves, not seeds.
 
But there’s a catch: a sudden warm spell after a cold snap can trigger bolting fast.
 
If your goal is to keep cilantro growing in cold weather for as long as possible, harvest leaves regularly.
 
Cutting the outer stems encourages fresh growth and slows the plant’s urge to flower.
 
You can also succession plant every few weeks so you always have a new batch coming up.
 
That way, even if one round of cilantro growing in cold weather gives out, another is right behind it.
 

So, Can Cilantro Grow in Cold Weather?

Cilantro can grow in cold weather, and it often thrives when temperatures are cool rather than hot.
 
It handles light frosts with ease and can survive mild freezes if you protect the roots.
 
Just remember that a hard freeze will kill the leaves, though the plant may return in spring.
 
With row covers, mulch, and a sheltered spot, you can keep cilantro growing in cold weather far longer than you might think.
 
So go ahead and plant a batch this fall, and enjoy fresh cilantro while the rest of the garden sleeps.
