When To Harvest Cilantro For Coriander Seeds

The best time to harvest cilantro for coriander seeds is when the plant’s flowers have dried and turned brown.
 
At that point, the seeds are mature and ready to be collected for use in your kitchen.
 
If you’ve ever wondered when to harvest cilantro for coriander seeds, the answer really comes down to watching the plant’s life cycle closely.
 
Cilantro and coriander are actually the same plant, just at different stages.
 
The leaves are cilantro, and the seeds are coriander.
 
So when you harvest cilantro for coriander seeds, you’re simply letting the plant bolt and go to seed.
 
In this post, we’ll walk through exactly when to harvest cilantro for coriander seeds, how to tell the seeds are ready, and how to collect and store them properly.
 
Let’s dive in.
 

When to Harvest Cilantro for Coriander Seeds

You should harvest cilantro for coriander seeds after the plant has fully flowered and the seed heads have turned brown.
 
This usually happens about 90 to 120 days after planting, depending on your climate.
 
Here’s how to time it right:
 

1. Wait for the Bolting Stage

Cilantro bolts quickly in warm weather, sending up a tall stalk with lacy white flowers.
 
That bolting stage is your first sign that the plant is transitioning from leaf production to seed production.
 
Don’t panic when your cilantro bolts, because that’s exactly what you want if your goal is coriander seeds.
 
When you harvest cilantro for coriander seeds, you’re actually letting the plant complete its natural cycle.
 

2. Watch for Brown, Dry Seed Heads

After the flowers fade, small green seeds will form.
 
These seeds start green and gradually turn tan or light brown.
 
The perfect time to harvest cilantro for coriander seeds is when most of the seed heads have turned brown and dry.
 
If you wait too long, the seeds will shatter and fall to the ground, and you’ll lose your harvest.
 
So check your plants every day once the seeds begin changing color.
 

3. Check for the Papery Layer

Each coriander seed is actually a pair of seeds enclosed in a thin, papery husk.
 
When that husk looks dry and papery, it’s a clear signal that you can harvest cilantro for coriander seeds.
 
Gently rub a seed head between your fingers.
 
If the seeds fall out easily, they’re ready.
 
If they’re still green and cling tightly, give them a few more days.
 

How to Harvest Cilantro for Coriander Seeds

Once you know when to harvest cilantro for coriander seeds, the actual harvesting process is pretty simple.
 
Here’s how to do it without losing seeds:
 

1. Cut the Stalks in the Morning

The best time of day to harvest cilantro for coriander seeds is early morning, after the dew has dried.
 
Cut the seed heads with sharp scissors or pruners, leaving a few inches of stem attached.
 
Have a paper bag or bucket ready to catch any seeds that fall.
 

2. Hang Them Upside Down to Dry

Tie the stems in small bundles and hang them upside down in a warm, dry, well-ventilated area.
 
Place a paper bag around each bundle to catch falling seeds.
 
This method ensures you get every last seed when you harvest cilantro for coriander seeds.
 

3. Thresh and Clean the Seeds

After about one to two weeks, the seeds should be completely dry and easy to separate.
 
Rub the seed heads between your hands or gently crush them in a bag.
 
Then winnow the seeds by pouring them between two bowls in front of a fan to blow away the chaff.
 

Tips for Getting the Best Coriander Seeds

Getting the timing right when you harvest cilantro for coriander seeds makes all the difference.
 
Here are a few extra pointers:
 

1. Don’t Harvest Too Early

Green coriander seeds have a fresh, citrusy flavor, but they don’t store well.
 
If you pick them too soon, they’ll lose their potency and may mold.
 
Wait until they’re brown for the best shelf life.
 

2. Plant Successively for a Longer Harvest

Cilantro bolts fast, so plant new seeds every two to three weeks.
 
That way, you’ll always have some plants ready to harvest cilantro for coriander seeds.
 

3. Choose Slow-Bolting Varieties

If you want more leaves before seeds, look for slow-bolting cilantro varieties.
 
But if seeds are your main goal, any variety will do.
 
Just let it flower and go to seed naturally.
 

So, When to Harvest Cilantro for Coriander Seeds?

You should harvest cilantro for coriander seeds when the seed heads have turned brown and dry.
 
That’s the sweet spot between green seeds that aren’t ready and brown seeds that are about to fall.
 
Watch your plants closely once they bolt, and check the seed heads daily.
 
When you harvest cilantro for coriander seeds at the right time, you’ll get a generous supply of aromatic coriander for your spice rack.
