How Long Does It Take For Cilantro To Grow

Cilantro takes about 3 to 4 weeks to reach a harvestable size when grown from seed.
 
If you’re asking how long does it take for cilantro to grow, the honest answer is that it depends on a few key factors like temperature, sunlight, and how you plant it.
 
Most gardeners find that cilantro grows fast in cool weather and slows down dramatically once the heat kicks in.
 
In this post, we’ll break down exactly how long cilantro takes to grow, what speeds it up or slows it down, and how to keep a steady supply coming all season.
 
Let’s dig in.
 

How Long Does It Take for Cilantro to Grow?

Cilantro is one of the fastest-growing herbs you can plant, which is great news if you’re impatient like me.
 
From the day you sow seeds, you can expect cilantro to grow to a usable size in roughly 3 to 4 weeks.
 
If you’re starting with transplants instead of seeds, that timeline shrinks to about 2 to 3 weeks before you can start snipping leaves.
 
The full life cycle, from seed to flowering and going to seed, usually wraps up in about 8 to 10 weeks depending on conditions.
 
So when people ask how long does it take for cilantro to grow, the short answer is: not long at all, as long as the weather cooperates.
 

1. Germination Takes 7 to 10 Days

Cilantro seeds, which are actually the coriander seeds you see in spice jars, germinate in about 7 to 10 days.
 
They need consistent moisture and soil temperatures between 55°F and 70°F to sprout well.
 
If it’s too hot, the seeds may stay dormant or germinate poorly, which is why spring and fall are the best times to start cilantro.
 

2. Leaf Growth Happens Fast in Cool Weather

Once the seedlings pop up, cilantro grows quickly in cool, mild conditions.
 
You’ll see the first true leaves within a week or two after germination.
 
This is when cilantro really starts to take off, adding new foliage every few days.
 

3. Harvest-Ready in 3 to 4 Weeks

By the 3 to 4 week mark, your cilantro should have enough leafy growth to start harvesting outer stems.
 
You don’t need to wait for the plant to reach full maturity because cilantro leaves are tender and flavorful at almost any stage.
 
Just snip what you need and let the rest keep growing.
 

Factors That Affect How Long Cilantro Takes to Grow

How long it takes for cilantro to grow isn’t set in stone.
 
A few things can speed it up or slow it way down.
 

1. Temperature Is the Biggest Factor

Cilantro loves cool weather, ideally between 50°F and 70°F.
 
When temperatures climb above 75°F, cilantro growth slows and the plant bolts, meaning it shoots up a flower stalk and stops producing tasty leaves.
 
That’s why cilantro grows fastest in spring and fall and struggles in the peak of summer.
 

2. Sunlight Matters More Than You Think

Cilantro grows best in full sun to partial shade.
 
In cooler climates, full sun keeps it growing steadily.
 
In hotter regions, a little afternoon shade helps cilantro grow longer before bolting.
 

3. Soil and Water Keep Growth Steady

Well-draining soil rich in organic matter gives cilantro the foundation it needs to grow fast.
 
Consistent moisture is key too, since dry soil stresses the plant and slows leaf production.
 
Aim for about an inch of water per week, either from rain or watering.
 

4. Succession Planting Extends Your Harvest

Since cilantro grows and bolts so quickly, many gardeners plant new seeds every 2 to 3 weeks.
 
This way, you always have a fresh batch of cilantro growing while older plants are finishing up.
 
It’s the easiest way to keep cilantro on hand all season long.
 

How to Make Cilantro Grow Faster

Want to speed things up?
 
There are a few simple tricks that help cilantro grow as quickly as possible.
 

1. Soak Seeds Before Planting

Cilantro seeds have a tough outer shell that can slow germination.
 
Gently crushing the seeds or soaking them overnight before planting can shave a few days off the sprouting time.
 

2. Keep Soil Consistently Moist

Dry soil is the enemy of fast cilantro growth.
 
Water lightly but regularly so the top inch of soil stays damp without getting soggy.
 

3. Avoid Extreme Heat

If you’re growing cilantro in summer, consider using shade cloth or planting in a spot that gets morning sun only.
 
Keeping cilantro cool is the single best way to make it grow faster and last longer.
 

4. Harvest Often

Regular harvesting actually encourages cilantro to grow more leaves.
 
Just don’t take more than a third of the plant at once, and it’ll keep producing for weeks.
 

So, How Long Does It Take for Cilantro to Grow?

Cilantro takes about 3 to 4 weeks to grow from seed to a harvestable size, and it grows even faster from transplants.
 
The key is giving it cool temperatures, steady moisture, and plenty of sunlight without overheating it.
 
Now that you know how long it takes for cilantro to grow, you can plan your planting schedule and enjoy fresh cilantro almost year-round.
 
Happy growing.
