When To Grow Cilantro From Seed

You can grow cilantro from seed almost any time of year, but the best window depends on your climate and the season.
 
Cilantro is a cool-weather herb, so timing your planting around mild temperatures is the real secret to a healthy harvest.
 
If you’ve been wondering when to grow cilantro from seed, the short answer is spring and fall in most regions.
 
In this post, we’ll walk through the best time to grow cilantro from seed, how to grow cilantro from seed step by step, and the mistakes that make cilantro bolt too fast.
 
Let’s dig in.
 

When to Grow Cilantro From Seed

Knowing when to grow cilantro from seed comes down to one big factor: heat.
 
Cilantro loves cool weather, so you want to grow cilantro from seed when temperatures are mild, not scorching.
 
Here’s how that breaks down by season.
 

1. Early Spring Is Prime Time

The best time to grow cilantro from seed is early spring, about two to three weeks before your last frost date.
 
Cilantro seeds germinate well in soil that’s around 55°F to 68°F.
 
If you plant too late in spring, the heat will hit right as your plants mature, and they’ll bolt almost overnight.
 
So get those seeds in the ground early and you’ll be harvesting tender leaves before summer arrives.
 

2. Fall Is the Second Best Window

If you live in a warm climate, fall is actually the ideal time to grow cilantro from seed.
 
Plant your cilantro seeds in late summer or early fall, once the worst heat has passed.
 
The plants will grow through the cooler months and give you a long, steady harvest.
 
In mild-winter areas, you can grow cilantro from seed in fall and keep harvesting right through winter.
 

3. Succession Planting Keeps You in Leaves

Since cilantro bolts quickly, smart gardeners grow cilantro from seed every two to three weeks during cool seasons.
 
This staggered approach means you always have a fresh batch coming up as the older one starts to flower.
 
It’s the easiest way to keep cilantro on your plate instead of watching it turn into a flower stalk.
 

How to Grow Cilantro From Seed Successfully

Once you know when to grow cilantro from seed, the next step is getting the planting right.
 
Here’s what actually works.
 

1. Prepare the Seeds First

Cilantro seeds are actually small round fruits that contain two seeds inside.
 
To grow cilantro from seed faster, gently crush the outer shell before planting.
 
This helps moisture reach the seed and speeds up germination, which can otherwise take two to three weeks.
 

2. Pick the Right Spot and Soil

Cilantro grows best in full sun to partial shade, with afternoon shade in warmer areas.
 
Loose, well-draining soil rich in organic matter gives you the strongest plants.
 
If you grow cilantro from seed in containers, use a pot at least 10 inches deep so the taproot has room.
 

3. Sow Seeds Shallowly

Plant cilantro seeds about a quarter inch deep and space them roughly six to eight inches apart.
 
Keep the soil consistently moist but not soggy while the seeds germinate.
 
Once seedlings appear, thin them so air can move between plants and disease stays away.
 

4. Water and Feed Lightly

Cilantro doesn’t need heavy feeding, but a light dose of balanced fertilizer helps young plants.
 
Water regularly, especially in warm weather, since dry soil pushes cilantro to bolt.
 
Mulching around your plants keeps the soil cool and slows that process down.
 

5. Harvest Often to Delay Bolting

The more you cut, the longer your cilantro keeps producing leaves.
 
Snip outer stems near the base and leave the center to keep growing.
 
If you grow cilantro from seed and harvest regularly, you’ll stretch your season by weeks.
 

Common Mistakes When You Grow Cilantro From Seed

Even seasoned gardeners run into trouble, so here are the pitfalls to avoid.
 

1. Planting in Peak Summer Heat

If you grow cilantro from seed in the middle of summer, it’ll bolt before you get a decent harvest.
 
Wait for cooler weather or provide shade to keep the plants happy.
 

2. Letting the Soil Dry Out

Cilantro is thirsty, and dry soil stresses the plant into flowering early.
 
Consistent moisture is one of the simplest ways to grow cilantro from seed without it bolting.
 

3. Skipping Succession Planting

Relying on one planting means a short harvest window.
 
If you want cilantro all season, grow cilantro from seed in small batches every few weeks.
 

So, When to Grow Cilantro From Seed?

You can grow cilantro from seed in early spring or fall, when temperatures stay cool and mild.
 
Timing is everything with this herb, since heat makes cilantro bolt and turn bitter fast.
 
Plant early, water consistently, harvest often, and you’ll enjoy fresh cilantro for months.
 
Now you know exactly when to grow cilantro from seed, so grab a packet and get planting.
