How Long Does It Take For Cilantro Seeds To Harvest

It takes cilantro seeds about 45 to 70 days to harvest after planting.
 
That timeline can stretch a bit longer if you’re growing cilantro seeds specifically for coriander spice rather than for fresh leaves.
 
If you’ve been wondering how long it takes for cilantro seeds to harvest, the answer really depends on whether you want the leafy greens or the dried seed pods.
 
Cilantro seeds are actually the same thing as coriander, so when you let your cilantro plants bolt and go to seed, you’re growing two harvests in one.
 
In this post, we’ll walk through the cilantro seed harvest timeline, how to tell when cilantro seeds are ready, and the best way to collect them.
 
Let’s dig in.
 

How Long Cilantro Seeds Take to Harvest

Cilantro seeds take roughly 45 to 70 days from planting to harvest, but the exact window shifts based on a few things.
 
Here’s what shapes that cilantro seed harvest timeline:
 

1. Cilantro Variety Matters

Some cilantro varieties are bred for slow bolting, which means they focus on leaf production longer before flowering.
 
Other varieties bolt fast, pushing up flower stalks within just a few weeks in warm weather.
 
The faster a cilantro plant bolts, the sooner you’ll have cilantro seeds to harvest.
 
So if your goal is cilantro seeds, a fast-bolting variety can actually work in your favor.
 

2. Weather and Temperature Play a Big Role

Cilantro loves cool weather, and when temperatures climb above 75°F, the plant rushes to flower and set seed.
 
That means cilantro seeds can be ready to harvest in as little as 45 days in hot climates.
 
In cooler regions, the same cilantro plant might take closer to 70 days or even longer.
 
If you’re counting the days for cilantro seeds to harvest, keep an eye on your local forecast.
 

3. Growing for Leaves vs. Seeds

If you’re harvesting cilantro leaves, you’ll usually start cutting within 3 to 4 weeks.
 
But for cilantro seeds, you have to let the plant bolt, flower, and form seed heads.
 
That extra stage adds several weeks, which is why the full cilantro seed harvest takes 45 to 70 days.
 
Patience is key when you’re growing cilantro seeds for coriander.
 

4. Soil and Sunlight Affect Speed

Cilantro planted in full sun with well-draining soil tends to grow faster and produce cilantro seeds sooner.
 
Too much shade slows growth, which delays when cilantro seeds are ready to harvest.
 
Keep the soil moist but not soggy, and your cilantro seeds will develop right on schedule.
 

When Are Cilantro Seeds Ready to Harvest?

Cilantro seeds are ready to harvest when the seed heads turn brown and dry on the plant.
 
Here’s how to spot the perfect moment:
 

1. Watch the Flower Heads Change Color

Cilantro flowers start out white or pale pink, then fade as the seeds form.
 
When the tiny green seeds inside the flower heads shift to a light brown, harvest time for cilantro seeds is close.
 
Don’t wait too long, though, because fully dry cilantro seeds will drop to the ground on their own.
 

2. Check for a Tan or Brown Hue

The seed pods holding your cilantro seeds will turn a tan or brown shade as they mature.
 
If you gently squeeze a pod and the seed inside feels firm and dry, those cilantro seeds are ready to harvest.
 
Green seeds mean the cilantro seeds still need more time on the plant.
 

3. Harvest in the Morning

The best time to collect cilantro seeds is in the morning after the dew has dried.
 
This is when the seed heads are dry but not yet baking in the midday heat.
 
Snip the stems just below the seed heads and place them in a paper bag.
 

4. Let Them Finish Drying Indoors

Once you’ve cut the stalks, hang the cilantro seed heads upside down in a paper bag for about a week.
 
As they dry, the cilantro seeds will drop right into the bottom of the bag.
 
This method makes harvesting cilantro seeds clean and easy, with almost no wasted seed.
 

Tips for a Bigger Cilantro Seed Harvest

Getting a good cilantro seed harvest comes down to a few simple habits.
 
Plant cilantro in early spring or late summer so it bolts naturally instead of stressing in the heat.
 
Let a few plants go to flower on purpose, since those are the ones that’ll give you cilantro seeds.
 
Succession plant every couple of weeks so you always have cilantro at different stages.
 
And once your cilantro seeds are dry, store them in an airtight jar away from sunlight.
 
They’ll keep for up to a year, ready to grind into coriander or plant for your next round.
 

So, How Long Does It Take for Cilantro Seeds to Harvest?

Cilantro seeds take about 45 to 70 days to harvest, depending on variety, weather, and growing conditions.
 
The warmer it is, the faster your cilantro plant bolts and the sooner those cilantro seeds are ready.
 
Just watch for brown, dry seed heads, harvest them in the morning, and let them finish drying in a paper bag.
 
With a little patience, you’ll have a full jar of cilantro seeds from your own garden.
