When To Plant Cilantro Seedlings In The Ground

Cilantro seedlings can go in the ground once nighttime temperatures stay above 50°F and all danger of frost has passed.
 
If you’re wondering when to plant cilantro seedlings in the ground, the short answer is simple: wait until the soil has warmed and the cold snaps are behind you.
 
Cilantro is a cool-season herb, so it actually prefers milder weather over the blazing heat of midsummer.
 
Timing this right means the difference between a lush, leafy harvest and a plant that bolts to seed before you can enjoy it.
 
In this post, we’ll walk through exactly when to plant cilantro seedlings in the ground, how to read your local weather, and the little tricks that keep your cilantro productive for longer.
 
Let’s dig in.
 

When to Plant Cilantro Seedlings in the Ground

Knowing when to plant cilantro seedlings in the ground comes down to watching your local temperatures more than checking a date on the calendar.
 
Cilantro grows best when the air sits between 50°F and 85°F, so your goal is to get seedlings settled while the weather is still mild.
 
Here’s how to nail the timing.
 

1. Wait Until the Last Frost Has Passed

The most important rule for when to plant cilantro seedlings in the ground is to wait until the last expected frost date for your area.
 
Cilantro seedlings are tender and a single frosty night can blacken their leaves overnight.
 
Check your local extension office or a reliable frost-date chart, then add about a week of buffer just to be safe.
 
If you plant cilantro seedlings in the ground too early, you risk losing them to a late cold snap.
 

2. Look for Soil Temperatures Around 55°F to 65°F

Soil temperature matters just as much as the air when you’re deciding when to plant cilantro seedlings in the ground.
 
Cilantro roots settle in fastest when the soil has warmed to at least 55°F.
 
A cheap soil thermometer takes the guesswork out of this.
 
Push it a few inches down in the morning, and if it reads in that 55°F to 65°F range, your cilantro seedlings are ready for the ground.
 

3. Plant in Early Spring or Early Fall

In most regions, the best window for when to plant cilantro seedlings in the ground is early spring, right after the frost lifts.
 
If you live somewhere with scorching summers, aim for an early fall planting instead.
 
Fall planting lets cilantro seedlings in the ground enjoy cooling temps as they establish.
 
This is especially handy in warm climates like the South, where spring planting often leads to fast bolting.
 

How to Plant Cilantro Seedlings in the Ground Successfully

Once you’ve figured out when to plant cilantro seedlings in the ground, the next step is getting them settled properly.
 
Good planting technique keeps your cilantro seedlings in the ground thriving instead of struggling.
 
Here’s what to do.
 

1. Harden Them Off First

Before you plant cilantro seedlings in the ground, give them a week of hardening off.
 
Set them outside for a few hours each day, gradually increasing their time in the sun and wind.
 
Skipping this step shocks the plants and can set them back weeks.
 

2. Choose a Spot With Morning Sun

When you plant cilantro seedlings in the ground, pick a location that gets morning sun and some afternoon shade.
 
Cilantro appreciates a break from the intense late-day heat.
 
Partial shade also slows bolting, which means more leaves for your salsa.
 

3. Space Them 6 to 8 Inches Apart

Give each seedling room to breathe by spacing them 6 to 8 inches apart.
 
If you’re planting cilantro seedlings in the ground in rows, keep the rows about a foot apart.
 
Good airflow cuts down on disease and keeps your cilantro seedlings growing steadily.
 

4. Water Deeply After Planting

Right after you plant cilantro seedlings in the ground, water them deeply to settle the soil around the roots.
 
Keep the soil consistently moist for the first week or two.
 
Cilantro seedlings in the ground don’t like to dry out completely, but soggy soil invites rot.
 

Tips to Keep Cilantro Seedlings Thriving After Planting

Getting the timing right for when to plant cilantro seedlings in the ground is half the battle.
 
Keeping them happy afterward is the other half.
 
Here are a few tricks that make a big difference.
 

1. Harvest Often to Delay Bolting

The more you snip, the longer your cilantro seedlings in the ground will keep producing leaves.
 
Regular harvesting signals the plant to keep growing foliage instead of rushing to seed.
 

2. Shade Them in Hot Weather

When summer heat kicks in, a shade cloth over your cilantro seedlings in the ground can buy you extra weeks.
 
Temps above 85°F push cilantro to bolt fast.
 

3. Succession Plant Every Few Weeks

If you love cilantro, don’t plant it all at once.
 
Stagger your plantings so you always have fresh cilantro seedlings in the ground at different stages.
 
This way, when one batch bolts, the next is ready to harvest.
 

So, When to Plant Cilantro Seedlings in the Ground?

Cilantro seedlings go in the ground once the last frost passes and soil temps reach about 55°F.
 
Timing this correctly keeps your cilantro seedlings in the ground happy, leafy, and slow to bolt.
 
Whether you plant cilantro seedlings in the ground in early spring or early fall, mild weather is your best friend.
 
Follow these tips, and you’ll enjoy a steady supply of fresh cilantro all season long.
