You can save cilantro seeds for next year by letting a few plants bolt, flower, and produce seeds, then collecting those seeds once they turn brown and dry.
It’s one of the easiest seed-saving projects you can tackle, even if you’ve never saved seeds before.
If you’re wondering how to save cilantro seeds for next year, the good news is that cilantro practically does the work for you.
Cilantro is an annual, which means it completes its whole life cycle in one season and then sets seeds to start the next generation.
Those seeds are what we call coriander, and they’re perfectly capable of growing brand new cilantro plants the following spring.
In this post, we’ll walk through how to save cilantro seeds for next year, when to harvest them, and how to store them so they stay viable until planting time.
Let’s dig in.
Why You Should Save Cilantro Seeds for Next Year
Saving cilantro seeds for next year is worth it for a few great reasons.
1. It Saves You Money
When you save cilantro seeds for next year, you skip buying new seed packets every spring.
One healthy cilantro plant can produce dozens of seeds, so a handful of plants can keep you stocked for seasons.
That’s money back in your pocket for other garden goodies.
2. You Get Coriander as a Bonus
The seeds you save cilantro seeds from are actually coriander, a popular spice.
You can grind a few up for cooking and still have plenty left to plant next year.
So saving cilantro seeds for next year gives you two harvests in one.
3. You Preserve Your Best Plants
If you save cilantro seeds for next year from plants that bolted slowly or had big, flavorful leaves, you’re selecting for those traits.
Over time, saving cilantro seeds from your strongest plants can give you a variety that’s perfectly suited to your garden.
That’s a huge win for any backyard grower.
When to Harvest Cilantro Seeds
Timing matters when you save cilantro seeds for next year.
1. Let Your Cilantro Bolt
To save cilantro seeds for next year, you first need to let your cilantro bolt, which means letting it send up a tall flower stalk.
This happens naturally when the weather warms up, and it’s nothing to panic about.
Those tiny white or pink flowers are the first step toward seed production.
2. Watch for Green Seeds to Turn Brown
After the flowers fade, small green seeds will form.
When you plan to save cilantro seeds for next year, wait until those seeds turn light brown and look dry.
Green seeds won’t germinate well, so patience here really pays off.
3. Harvest Before They Drop
Cilantro seeds shatter easily, meaning they fall off the plant once they’re fully dry.
If you want to save cilantro seeds for next year, check your plants every day or two once the seeds start browning.
The moment they’re dry but still attached, it’s time to act.
How to Save Cilantro Seeds for Next Year Step by Step
Here’s the simple process to save cilantro seeds for next year.
1. Snip the Seed Heads
Use clean scissors to cut the seed heads off, leaving a bit of stem attached.
Drop them gently into a paper bag or a bowl as you go.
This is the easiest way to save cilantro seeds for next year without losing them to the soil.
2. Let Them Dry Fully
Spread the seed heads out in a single layer on a screen, tray, or paper towel.
Leave them in a cool, dry spot with good airflow for about one to two weeks.
You’ll know they’re ready when the seeds rattle slightly and crush easily.
3. Separate the Seeds
Once dry, rub the seed heads between your fingers or roll them gently to release the seeds.
Pick out any stems, leaves, or chaff so you’re left with clean seed.
This step makes it much easier to store and plant them later.
4. Store Them Properly
Place your saved cilantro seeds in a paper envelope or a small glass jar with a tight lid.
Label it with the variety and the date so you remember what you planted.
Store the container in a cool, dark, dry place like a cupboard or garage shelf.
5. Keep Them Dry and Cool
Moisture and heat are the enemies of stored seed.
If you save cilantro seeds for next year and stash them somewhere damp, they may mold or lose viability.
A simple airtight jar in a dark spot keeps them fresh for two to three years.
Tips to Save Cilantro Seeds for Next Year Successfully
A few extra pointers can make your seed-saving even smoother.
1. Don’t Wash the Seeds
When you save cilantro seeds for next year, resist the urge to rinse them.
Water invites mold, and dry seeds store far better.
Just brush off any debris and let them be.
2. Save Seeds from Multiple Plants
To keep genetic diversity strong, save cilantro seeds for next year from several healthy plants rather than just one.
This gives you more robust seedlings down the road.
3. Do a Germination Test
Before planting, you can test a few seeds on a damp paper towel to see if they sprout.
If you save cilantro seeds for next year and they germinate well, you’re golden.
If not, you’ll know to grab a fresh packet.
So, How Do You Save Cilantro Seeds for Next Year?
You save cilantro seeds for next year by letting your cilantro bolt, waiting for the seeds to turn brown, harvesting them before they drop, and storing them dry and cool.
