How Long Does Cilantro Seeds Take To Germinate

Cilantro seeds take about 7 to 10 days to germinate under ideal conditions.
 
That said, the answer to how long cilantro seeds take to germinate can stretch to 14 days or even 3 weeks if the weather is cool or the soil is too dry.
 
Cilantro, also known as coriander, is a fast-growing herb once it gets going, but the germination stage is where most gardeners get impatient.
 
If you’ve been wondering how long cilantro seeds take to germinate, the honest answer is that it depends on soil temperature, moisture, and how you prepare the seeds.
 
In this post, we’ll break down exactly how long cilantro seeds take to germinate, what speeds up the process, and what slows it down.
 
Let’s dig in.
 

How Long Cilantro Seeds Take to Germinate

Cilantro seeds take roughly 7 to 10 days to germinate when soil temperatures sit between 65°F and 70°F.
 
That’s the sweet spot.
 
When temperatures drop below 60°F, cilantro seeds take longer to germinate, sometimes up to 3 weeks.
 
And if the soil gets too warm, above 85°F, germination slows down and the seeds may even go dormant.
 
So the real answer to how long cilantro seeds take to germinate is: it depends on warmth.
 
Here’s what else affects the timeline.
 

1. Soil Temperature Is the Biggest Factor

Cilantro seeds germinate fastest in cool-to-mild soil, ideally 65°F to 70°F.
 
This is why spring and fall plantings sprout quicker than midsummer ones.
 
If you’re starting cilantro seeds indoors, a heat mat set to 65°F can help.
 
Just don’t crank it up too high, because cilantro actually prefers things on the cooler side, and too much heat will slow germination instead of speeding it up.
 

2. Seed Preparation Makes a Difference

Cilantro seeds are actually two seeds inside one husk, which is why they look like little round balls.
 
That tough outer shell is one reason cilantro seeds take a while to germinate.
 
To speed things up, gently crush the seeds with the back of a spoon before planting.
 
This splits the husk and lets moisture reach the seeds faster, shaving a few days off how long cilantro seeds take to germinate.
 

3. Moisture and Soil Matter

Cilantro seeds need consistent moisture to germinate, not soggy soil.
 
Keep the soil evenly damp, like a wrung-out sponge.
 
A light misting twice a day works better than a heavy watering that drowns the seeds.
 
Loose, well-draining soil also helps cilantro seeds germinate on schedule, because compacted soil traps water and starves the seeds of oxygen.
 

How to Speed Up Cilantro Seed Germination

If you want cilantro seeds to germinate faster, a few simple tricks can cut the waiting time down.
 

1. Soak the Seeds Overnight

Soaking cilantro seeds in water for 12 to 24 hours before planting softens the husk and speeds up germination.
 
This alone can shave 2 to 3 days off how long cilantro seeds take to germinate.
 
Just don’t soak them longer than a day, or the seeds can rot.
 

2. Plant at the Right Depth

Cilantro seeds should be planted about a quarter inch deep.
 
Too deep, and the seedlings struggle to push through.
 
Too shallow, and the seeds dry out before they sprout.
 
Getting the depth right helps cilantro seeds germinate evenly and quickly.
 

3. Keep the Temperature Steady

Fluctuating temperatures confuse seeds and stall germination.
 
Aim for a steady 65°F to 70°F, whether indoors or outdoors.
 
If you’re planting in summer, start cilantro seeds indoors in a cooler spot, then transplant them once they sprout.
 

4. Be Patient With Direct Sowing

Cilantro doesn’t love being transplanted, so many gardeners sow the seeds directly in the garden.
 
That’s fine, just expect cilantro seeds to germinate a bit slower outdoors because you can’t control the weather.
 
Keep the soil moist and give them 10 to 14 days.
 

Common Mistakes That Slow Cilantro Seed Germination

Even seasoned gardeners run into problems with cilantro seeds taking too long to germinate.
 
Here are the usual culprits.
 

1. Letting the Soil Dry Out

Cilantro seeds need steady moisture from day one.
 
If the soil dries out even once during the germination window, the seeds can stall or die.
 
Check the soil daily and mist as needed.
 

2. Planting in Hot Weather

Cilantro is a cool-season herb, and hot soil slows germination.
 
If you’re planting cilantro seeds in the middle of summer, expect them to take longer to germinate, or wait until fall when temperatures drop.
 

3. Skipping the Seed Crush

Whole cilantro seeds take longer to germinate because the husk blocks moisture.
 
Crushing them first is a small step that makes a big difference in how long cilantro seeds take to germinate.
 

So, How Long Do Cilantro Seeds Take to Germinate?

Cilantro seeds take about 7 to 10 days to germinate in ideal conditions, though it can take up to 3 weeks if the soil is cool or dry.
 
The key is warm-but-not-hot soil, consistent moisture, and cracking the seed husk before planting.
 
Do those three things, and you’ll cut down the wait time significantly.
 
Now that you know how long cilantro seeds take to germinate, you can plan your planting schedule and enjoy fresh cilantro sooner.
 
Happy planting.
