Cilantro usually takes 7 to 10 days to germinate under ideal conditions.
That said, the answer to how long does cilantro take to germinate isn’t always that simple.
Some seeds sprout in as little as 5 days, while others can take up to 3 weeks depending on soil temperature, moisture, and seed quality.
Cilantro is notoriously finicky compared to other herbs, so if your seeds are taking their sweet time, you’re definitely not alone.
In this post, we’ll break down exactly how long cilantro takes to germinate, what factors speed up or slow down the process, and how to get those little green sprouts to show up faster.
Let’s dig in.
How Long Does Cilantro Take to Germinate?
On average, cilantro seeds germinate in about 7 to 10 days when soil temperatures sit between 55°F and 70°F.
If conditions are perfect, you might see sprouts in 5 to 7 days.
But if it’s too hot, too cold, or the soil dries out, cilantro germination can stretch to 14 or even 21 days.
So when someone asks how long does cilantro take to germinate, the honest answer is: it depends, but usually around a week to ten days.
1. Soil Temperature Plays a Huge Role
Cilantro germinates best in cool soil, ideally between 55°F and 68°F.
Once soil temperatures climb above 75°F, cilantro germination slows down dramatically.
That’s why spring and fall plantings tend to sprout faster than midsummer ones.
If you’re growing cilantro in a hot climate, starting seeds indoors or in partial shade can help you hit that sweet spot.
2. Seed Quality and Age Matter
Fresh cilantro seeds germinate faster than old ones.
Cilantro seeds are actually the dried fruits of the plant, and each one contains two seeds inside.
That’s why you’ll often see two sprouts come up from a single seed ball.
If your seeds have been sitting in a drawer for a couple of years, expect cilantro germination to take longer, if it happens at all.
3. Moisture Is Non-Negotiable
Cilantro seeds need consistent moisture to germinate.
Not soggy soil, but evenly damp.
If the top inch of soil dries out, the germination process stalls.
A light misting twice a day or a gentle watering with a spray bottle keeps things on track.
How to Speed Up Cilantro Germination
If you want cilantro to germinate faster, a few simple tricks can shave days off the process.
1. Soak the Seeds Overnight
Cilantro seeds have a tough outer shell that slows down water absorption.
Soaking them in room-temperature water for 12 to 24 hours softens that shell and kickstarts germination.
Just don’t soak them longer than a day, or they can rot.
2. Crack the Seed Coat Gently
Because each cilantro seed is actually a two-part fruit, gently pressing on it with the back of a spoon to split it apart can speed things up.
This exposes the inner seeds to moisture faster, which means cilantro germination happens sooner.
3. Keep the Soil Consistently Warm (But Not Hot)
Aim for soil temps around 60°F to 65°F.
A heating mat set on low can help in early spring, but turn it off once sprouts appear.
Too much heat will actually slow cilantro germination and encourage bolting later on.
4. Sow Seeds Directly Where They’ll Grow
Cilantro has a taproot and doesn’t transplant well.
Sowing seeds directly into the garden or a final container avoids transplant shock and keeps germination on schedule.
If you must start indoors, use biodegradable pots you can plant whole.
Common Mistakes That Delay Cilantro Germination
Even seasoned gardeners run into problems with cilantro germination.
Here are the most common culprits.
1. Planting Too Deep
Cilantro seeds only need about a quarter inch of soil covering them.
Plant them deeper than half an inch, and they’ll struggle to push through.
2. Letting the Soil Dry Out
Inconsistent moisture is the number one reason cilantro germination fails.
Check the soil daily and water lightly whenever the surface feels dry to the touch.
3. Starting in Hot Weather
Cilantro is a cool-season herb.
If you sow seeds when daytime temps are consistently above 80°F, germination will be spotty at best.
Wait for cooler weather or start your cilantro indoors with air conditioning nearby.
So, How Long Does Cilantro Take to Germinate?
Cilantro takes about 7 to 10 days to germinate under ideal conditions.
But it can take up to 3 weeks if the soil is too warm, too dry, or the seeds are old.
Soaking seeds overnight, keeping the soil moist, and planting at the right temperature will help you hit that 7-to-10-day window.
Now that you know how long cilantro takes to germinate, you can plan your planting schedule with confidence and enjoy fresh cilantro sooner.
