Why Are My Cilantro Seeds Not Sprouting

Cilantro seeds not sprouting is one of the most common frustrations for home gardeners.
 
You sow them with high hopes, wait patiently, and then… nothing.
 
If you’ve been wondering why your cilantro seeds are not sprouting, you’re definitely not alone.
 
Cilantro seeds not sprouting usually comes down to a few key issues like temperature, water, and how the seeds were handled.
 
In this post, we’ll dig into the real reasons your cilantro seeds are not sprouting and how to fix each one.
 
Let’s get to it.
 

Why Your Cilantro Seeds Are Not Sprouting

Cilantro seeds not sprouting is rarely random.
 
There’s almost always a reason, and once you know it, you can turn things around fast.
 
Here are the biggest culprits behind cilantro seeds not sprouting.
 

1. The Seeds Are Still in Their Hard Shell

Here’s something many gardeners don’t realize: what we call a cilantro seed is actually a fruit that holds two seeds inside.
 
That outer shell is tough, and it can take forever for moisture to penetrate it.
 
If your cilantro seeds are not sprouting, this hard coat is often the reason.
 
The fix is simple.
 
Gently crush the seeds with the back of a spoon or a rolling pin before planting.
 
This splits the shell and lets water reach the seed inside, which speeds up sprouting dramatically.
 

2. The Soil Is Too Warm

Cilantro is a cool-season herb, and that matters more than you’d think.
 
When soil temperatures climb above 75°F, cilantro seeds not sprouting becomes very common.
 
The seeds actually go into a sort of heat-induced dormancy.
 
So if you planted in the middle of summer, that’s likely your problem.
 
Try sowing cilantro in early spring or in early fall when the soil is cooler.
 
If you’re planting in summer anyway, give the bed some shade and keep the soil consistently moist.
 

3. You Planted Too Deep

Cilantro seeds are small, and they don’t have much energy to push through heavy soil.
 
If you buried them more than a quarter inch deep, your cilantro seeds not sprouting makes perfect sense.
 
Light is not the issue here, but depth is.
 
The deeper the seed, the farther it has to travel to reach the surface, and many simply run out of steam.
 
Aim for about 1/8 to 1/4 inch deep, barely covered with soil.
 
Press them in gently and water lightly so they settle without being buried further.
 

4. The Soil Dried Out

Cilantro seeds need constant moisture to germinate, and “constant” is the key word here.
 
If the soil dries out even for a day or two, the germination process stops.
 
And once it stops, it often doesn’t restart.
 
This is a huge reason cilantro seeds are not sprouting for so many gardeners.
 
Water gently every day, or even twice a day in warm weather, until you see sprouts.
 
A light mist from a spray bottle works great because it won’t disturb the seeds.
 

5. The Seeds Were Old or Poorly Stored

Seed viability drops over time, and cilantro is no exception.
 
If your cilantro seeds have been sitting in a hot garage or a damp drawer for a couple of years, they may simply be dead.
 
Cilantro seeds not sprouting from old packets is incredibly common.
 
Try a simple test before planting.
 
Place a few seeds on a damp paper towel, fold it, and keep it moist for a week.
 
If nothing happens, it’s time for fresh seeds.
 

How to Get Cilantro Seeds to Sprout Every Time

Now that you know why cilantro seeds are not sprouting, let’s talk about what actually works.
 
First, always start with fresh seeds from a reliable source.
 
Second, crush the outer shell before planting to expose the seeds inside.
 
Third, sow shallow, no more than a quarter inch deep.
 
Fourth, keep the soil evenly moist, never soggy and never dry.
 
Fifth, plant when temperatures are mild, ideally between 60°F and 70°F.
 
If you follow these steps, cilantro seeds not sprouting will stop being your problem.
 
You should see little green sprouts poking through in about seven to ten days.
 
And once they’re up, thin them so each plant has room to grow.
 

So, Why Are My Cilantro Seeds Not Sprouting?

Cilantro seeds are not sprouting because of hard seed coats, warm soil, deep planting, dry conditions, or old seeds.
 
The good news is that every single one of these issues is fixable.
 
Crush the seeds, plant them shallow, keep the soil moist, and sow when the weather is cool.
 
Do that, and your cilantro seeds will sprout just fine.
 
Hope this post has helped you figure out why your cilantro seeds are not sprouting and how to get them growing.
 
Happy planting.
