How Long Does Cilantro Seeds Take To Germinate

Cilantro seeds take about 7 to 10 days to germinate under ideal conditions.
 
That timeline can stretch to 14 days or even 21 days if the weather is cool or the seeds are planted too deep.
 
If you’ve been wondering how long cilantro seeds take to germinate, the short answer is usually around one to two weeks.
 
Cilantro seeds are actually tiny fruits called schizocarps, and each one contains two seeds inside.
 
That little detail matters because it affects how fast cilantro seeds germinate and how many plants you get per seed.
 
In this post, we’ll cover how long cilantro seeds take to germinate, what speeds up or slows down the process, and how to get better germination rates.
 
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 55°F and 70°F.
 
That’s the sweet spot.
 
When it’s warmer than that, cilantro seeds germinate faster but the plants bolt quickly.
 
When it’s cooler, germination slows down and cilantro seeds can take up to three weeks to sprout.
 
So how long cilantro seeds take to germinate really depends on the conditions you give them.
 
Here’s what influences that timeline the most:
 

1. Soil Temperature

Soil temperature is the biggest factor in how long cilantro seeds take to germinate.
 
Cilantro prefers cooler soil, ideally between 55°F and 70°F.
 
In that range, cilantro seeds germinate in about 7 to 10 days.
 
Above 75°F, germination can still happen but the seedlings get stressed fast.
 
Below 50°F, cilantro seeds take much longer to germinate and some may rot before they sprout.
 

2. Seed Age and Quality

Fresh cilantro seeds germinate faster than old ones.
 
Cilantro seeds lose viability quickly, so seeds that are more than a year or two old may take longer to germinate or fail completely.
 
If you’re working with older seeds, expect cilantro seeds to take closer to 14 to 21 days to germinate, if they sprout at all.
 
Buying fresh seeds each season is the easiest way to keep that germination window short.
 

3. Planting Depth

Cilantro seeds need light to germinate, so planting them too deep slows everything down.
 
A quarter-inch to half-inch deep is plenty.
 
When cilantro seeds are buried too far, they use up their stored energy before reaching the surface and germination takes longer or fails.
 
Shallow planting keeps cilantro seeds on track to germinate in that 7 to 10 day window.
 

4. Moisture Levels

Consistent moisture matters just as much as temperature.
 
Cilantro seeds need evenly moist soil, not soggy soil.
 
Dry soil stalls germination, while waterlogged soil causes seeds to rot.
 
A light misting every day or two keeps cilantro seeds germinating steadily without drowning them.
 

How to Speed Up Cilantro Seed Germination

If you want cilantro seeds to germinate faster, there are a few tricks that actually work.
 
These methods can shave several days off how long cilantro seeds take to germinate.
 
Here’s what to try:
 

1. Soak the Seeds Overnight

Soaking cilantro seeds in water for 12 to 24 hours before planting softens the tough outer shell.
 
That shell is the main reason cilantro seeds take so long to germinate compared to other herbs.
 
Soaking gives moisture a head start, so cilantro seeds germinate in as little as 5 to 7 days.
 
Just don’t soak them longer than a day, or the seeds can rot.
 

2. Crack the Seed Coat Gently

Since each cilantro seed is actually two seeds inside a husk, gently crushing the husk helps.
 
You can roll the seeds between your fingers or press them with the back of a spoon until you hear a small crack.
 
This is called scarification, and it’s one of the fastest ways to get cilantro seeds to germinate.
 
Be gentle though, because crushing the inner seeds ruins them.
 

3. Keep the Soil Consistently Moist

Cilantro seeds germinate best in soil that stays moist but never soaked.
 
A spray bottle works better than a watering can at this stage.
 
Covering the seed tray with a humidity dome or plastic wrap traps moisture and keeps cilantro seeds germinating evenly.
 
Just remove the cover once you see sprouts, or the seedlings will damp off.
 

4. Start Seeds Indoors or in Fall

If you’re growing in a hot climate, cilantro seeds germinate much better indoors or in a fall planting.
 
Starting cilantro seeds indoors gives you control over temperature and moisture.
 
Fall planting works because the soil cools down naturally, which is exactly what cilantro seeds germinate best in.
 

Common Mistakes That Slow Down Cilantro Seed Germination

A lot of gardeners give up on cilantro because they think the seeds are bad.
 
Usually, it’s just one of these mistakes:
 

1. Planting Too Deep

Cilantro seeds planted more than half an inch deep take much longer to germinate or never sprout.
 
Keep them shallow and barely covered with soil.
 

2. Letting the Soil Dry Out

Even one dry day can set cilantro seeds back by several days.
 
Check moisture daily until the seedlings are up.
 

3. Planting in Hot Weather

Cilantro seeds germinate poorly when soil temps climb above 80°F.
 
If you’re planting in summer, start cilantro seeds indoors instead.
 

4. Using Old Seeds

Cilantro seeds don’t stay viable long, so old packets are often the reason cilantro seeds take forever to germinate.
 
Fresh seeds every season solve this problem fast.
 

So, How Long Does Cilantro Seeds Take to Germinate?

Cilantro seeds take about 7 to 10 days to germinate in ideal conditions, and up to three weeks in cooler or less ideal ones.
 
Factors like soil temperature, planting depth, seed age, and moisture all affect how long cilantro seeds take to germinate.
 
If you soak the seeds, crack the husk, and keep the soil evenly moist, cilantro seeds germinate faster and more reliably.
 
Hope this post has helped you understand how long cilantro seeds take to germinate and how to speed up the process.
