Why Is My Cilantro Not Germinating

Cilantro not germinating is one of the most common frustrations for home gardeners, and the reason usually comes down to a few specific things.
 
If your cilantro seeds aren’t sprouting, it’s often because the seeds are too old, the soil is too warm, or the seeds were planted too deep.
 
The good news is that cilantro is actually a fast germinator when conditions are right, so fixing the problem is usually straightforward.
 
In this post, we’ll look at the main reasons cilantro seeds fail to germinate and how to get them sprouting quickly.
 
Let’s dig in.
 

Why Your Cilantro Is Not Germinating

Cilantro not germinating can happen for several reasons, but most of them trace back to seed quality, temperature, or planting depth.
 
Here are the biggest culprits.
 

1. The Seeds Are Too Old

Cilantro seeds, which are actually the plant’s dried fruits called coriander, have a fairly short shelf life compared to other herbs.
 
If your cilantro seeds are more than a year or two old, the germination rate drops sharply.
 
This is one of the most overlooked reasons cilantro is not germinating, since the seeds look perfectly fine on the outside.
 
If you’re unsure about the age of your cilantro seeds, do a quick germination test between damp paper towels before planting.
 

2. Cilantro Seeds Need Light to Sprout

Another reason cilantro is not germinating is because the seeds were buried too deep.
 
Cilantro seeds need light to germinate, so they should only be covered with about a quarter inch of soil.
 
If you planted your cilantro seeds any deeper than half an inch, they may struggle or fail to sprout entirely.
 
Next time, scatter the cilantro seeds on the surface and press them gently into the soil instead of burying them.
 

3. The Soil Is Too Warm

Cilantro is a cool-season herb, and its seeds germinate best in soil between 55°F and 68°F.
 
If you’re planting cilantro in the middle of summer, the warm soil can keep the seeds dormant, which is a huge reason cilantro is not germinating.
 
This is why cilantro planted in late spring or early fall germinates far more reliably than cilantro planted in July.
 
If you’re dealing with warm soil, try starting your cilantro seeds indoors or provide some shade to keep the soil cooler.
 

4. The Seeds Were Not Scarified

Each cilantro seed is actually a husk containing two seeds, and that tough outer shell can slow down germination significantly.
 
Gently crushing or rubbing the cilantro seeds between your fingers before planting helps break that husk and speeds up sprouting.
 
Without this step, cilantro can take two to three weeks to germinate, and some seeds may never sprout at all.
 
So if your cilantro is not germinating, try scarifying the seeds first and watch the difference.
 

5. The Soil Is Too Dry or Too Wet

Cilantro seeds need consistently moist soil to germinate, but they also hate being waterlogged.
 
If the soil dries out even once during the germination period, the cilantro seeds may die before they ever sprout.
 
On the flip side, soggy soil can cause the seeds to rot, which is another common reason cilantro is not germinating.
 
Mist the soil daily to keep it evenly moist without soaking it, and you’ll see much better results.
 

How to Get Cilantro Seeds to Germinate Faster

If your cilantro is not germinating, a few simple tricks can turn things around fast.
 
Here’s how to give your cilantro seeds the best possible start.
 

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 is one of the easiest fixes if your cilantro is not germinating, since moisture is often the missing piece.
 
Just make sure to plant the soaked cilantro seeds right away so they don’t dry out.
 

2. Plant at the Right Time

Timing matters more than most gardeners realize when it comes to cilantro.
 
Plant cilantro seeds in early spring or early fall when the soil is naturally cool, and you’ll rarely have issues with cilantro not germinating.
 
If you live in a hot climate, cilantro grows best as a fall or winter crop.
 

3. Keep the Soil Consistently Moist

Watering gently every day, or even twice a day in dry weather, keeps cilantro seeds on track.
 
A spray bottle works great here because it prevents the seeds from being washed away or buried too deep.
 
Consistency is the key to avoiding cilantro not germinating, so don’t let the soil dry out during those first two weeks.
 

4. Be Patient

Even under perfect conditions, cilantro can take 7 to 14 days to germinate, and up to 21 days if the seeds weren’t scarified.
 
So if your cilantro is not germinating after just a few days, don’t panic yet.
 
Give it a full three weeks before you assume the cilantro seeds have failed.
 

So, Why Is My Cilantro Not Germinating?

Cilantro not germinating usually comes down to old seeds, warm soil, planting too deep, or skipping scarification and soaking.
 
Cilantro needs cool temperatures, light coverage, and consistent moisture to sprout well.
 
Fix those few things, and your cilantro seeds will germinate far more reliably.
 
Try scarifying your cilantro seeds, soaking them overnight, and planting them shallow in cool soil, and you should see sprouts within a week or two.
 
Happy planting.
