How To Harvest Coriander Seeds From Cilantro Plant

You can harvest coriander seeds from your cilantro plant by letting the plant bolt, flower, and then allowing those flowers to dry out and turn brown before collecting the seeds.
 
It’s a simple process that rewards you with a steady supply of the spice that’s probably sitting in your kitchen cabinet right now.
 
If you’ve ever wondered how to harvest coriander seeds from cilantro plant, you’re in the right place because the two are literally the same plant.
 
Cilantro is the leafy green you toss into tacos and salsas while coriander is the dried seed that comes from the very same herb once it matures.
 
In this post, we’ll walk through exactly how to harvest coriander seeds from cilantro plant step by step so you can stop buying tiny jars and start collecting your own.
 
Let’s dig in.
 

How to Harvest Coriander Seeds from Cilantro Plant

Harvesting coriander seeds from cilantro plant starts with letting your cilantro go to seed instead of fighting it.
 
Most gardeners panic when their cilantro bolts but that tall, lanky stalk is actually the beginning of your coriander harvest.
 
Here’s the full journey from leafy herb to spice jar:
 

1. Let Your Cilantro Bolt

The first step in how to harvest coriander seeds from cilantro plant is allowing the plant to bolt.
 
Bolting happens when cilantro sends up a tall central stalk that produces delicate white or pale pink flowers.
 
This usually kicks in when temperatures rise above 75°F or when the plant reaches maturity after about 45 to 60 days.
 
Don’t cut that stalk because if you keep harvesting leaves, the plant just keeps making leaves.
 
Let it do its thing.
 

2. Watch for Flowers and Pollination

Once the flowers open, bees and other pollinators will do the heavy lifting for you.
 
Each tiny flower has the potential to become a seed, and pollination is what makes that happen.
 
This stage is critical when you harvest coriander seeds from cilantro plant because unpollinated flowers simply wither without producing anything.
 
Give your cilantro plenty of sun and don’t spray it with insecticides during this time, so the pollinators can finish their job.
 

3. Wait for the Seeds to Turn Brown

After the flowers fade, small green seed pods will appear at the top of the plant.
 
These pods start out green and slowly shift to a tan or light brown color as they dry.
 
This color change is your signal that the coriander seeds inside are ready.
 
If you pick too early, the seeds won’t have that warm, citrusy flavor you expect from coriander.
 
Give them time and check on them every couple of days.
 

4. Harvest at the Right Moment

The trickiest part of how to harvest coriander seeds from cilantro plant is timing because seeds shatter and drop when they’re fully dry.
 
You want to harvest when most of the seeds on a head have turned brown but before they start falling to the ground.
 
A good rule is to check in the morning when dew makes the seeds slightly less likely to scatter.
 
Snip the entire seed head off with clean scissors and hold a bowl underneath to catch any strays.
 

How to Dry and Store Coriander Seeds

After you harvest coriander seeds from cilantro plant, the next step is drying them properly so they don’t mold.
 
Here’s how to handle that part:
 

1. Dry the Seed Heads

Tie the stems together with twine and hang them upside down in a paper bag with the top open for airflow.
 
Alternatively, lay the seed heads flat on a screen or tray in a warm, dry room away from direct sun.
 
Let them sit for one to two weeks until the seeds feel completely hard and rattle inside their pods.
 

2. Separate the Seeds from the Chaff

Once dry, rub the seed heads between your fingers or gently roll them in your palms over a bowl.
 
The pods will crumble and release the round, tan coriander seeds inside.
 
Pick out any stems or debris then store the clean seeds in an airtight jar away from heat and light.
 
They’ll keep for about a year, though grinding them fresh gives you the best flavor.
 

Common Mistakes When You Harvest Coriander Seeds from Cilantro Plant

Even though the process is simple, a few missteps can ruin your harvest.
 
Watch out for these:
 

1. Picking the Seeds Too Early

Green coriander seeds won’t dry into the spice you want, so always wait for that brown color.
 

2. Letting the Seeds Fall

If you wait too long, the pods split open and scatter seeds onto the soil, leaving you with nothing to collect.
 

3. Skipping the Drying Step

Seeds that aren’t fully dry will rot in storage, so don’t rush this part.
 

So, How Do You Harvest Coriander Seeds from Cilantro Plant?

You harvest coriander seeds from cilantro plant by letting the herb bolt, flower, and produce seed heads that turn brown before you snip them off.
 
Then you dry those heads, rub the seeds loose, and store them in an airtight jar for cooking.
 
It’s one of those garden tasks that feels like a bonus because you get cilantro leaves early in the season and coriander seeds later on.
 
Give it a try this year and you might never buy coriander from the store again.
