When To Plant Cilantro In Minnesota

The best time to plant cilantro in Minnesota is in the spring after your last frost date, usually between mid-May and early June.
 
Cilantro loves cool weather, so if you plant it too late, the summer heat will make it bolt and go to seed almost instantly.
 
But if you plant at the right moment, you’ll enjoy fresh leaves for weeks, and you can even keep sowing more seeds for a continuous harvest all season.
 
In this post, we’ll cover exactly when to plant cilantro in Minnesota, how to time it around the state’s unpredictable weather, and tips to keep your cilantro producing as long as possible.
 
Let’s dig in.
 

When to Plant Cilantro in Minnesota

When you plant cilantro in Minnesota really comes down to understanding your local frost dates and the plant’s short lifespan in warm weather.
 
Here’s the breakdown:
 

1. Wait Until After the Last Frost

Cilantro seeds germinate best when soil temperatures are between 55°F and 68°F.
 
Minnesota’s last frost typically falls between early May in the southern part of the state and late May in northern areas.
 
So the safest window to plant cilantro in Minnesota is mid to late May for most gardeners.
 
If you plant too early, a surprise frost can kill your seedlings overnight.
 

2. Plant in Mid-May for Central and Southern MN

If you’re in the Twin Cities, Mankato, Rochester, or anywhere in southern Minnesota, you can usually plant cilantro around mid-May.
 
The soil has warmed up enough by then, and the nights are still cool, which cilantro absolutely loves.
 
This timing gives you a solid month or two of leaf production before the real heat hits.
 

3. Wait Until Late May or Early June in Northern MN

For gardeners in Duluth, Bemidji, Grand Rapids, and other northern spots, you’ll want to wait until late May or even the first week of June to plant cilantro.
 
Your last frost date is later, and the soil takes longer to warm up.
 
Planting cilantro too early in northern Minnesota means slow germination and weak growth.
 

4. Use Succession Planting for a Longer Harvest

One of the smartest things you can do when you plant cilantro in Minnesota is to sow seeds every two to three weeks.
 
This staggered approach means that when one batch bolts, the next one is ready to take over.
 
Start your first sowing in mid-May, then sow again in early June, mid-June, and even early July if you’re in a cooler area.
 

5. Fall Planting Is an Option, Too

If you want a fall crop, you can plant cilantro in Minnesota again in late August or early September.
 
The cooler fall temperatures mimic spring conditions, which cilantro thrives in.
 
Just make sure to water consistently, and you’ll get fresh leaves before the first hard freeze.
 

How to Plant Cilantro in Minnesota for Best Results

Knowing when to plant cilantro in Minnesota is half the battle, but how you plant it matters, too.
 
Here are a few key tips:
 

1. Choose the Right Spot

Cilantro prefers full sun in spring but appreciates partial shade as summer heats up.
 
In Minnesota, a spot that gets morning sun and afternoon shade is ideal, especially for late spring plantings.
 

2. Amend Your Soil

Cilantro grows best in loose, well-draining soil with a pH between 6.2 and 6.8.
 
Mix in some compost before planting to give your cilantro a good start.
 

3. Sow Seeds Directly

Cilantro doesn’t transplant well because of its taproot.
 
So when you plant cilantro in Minnesota, sow the seeds directly into the garden bed about a quarter-inch deep.
 
Space them about six inches apart, and keep the soil consistently moist until they sprout.
 

4. Water Consistently but Don’t Overdo It

Cilantro needs regular watering, especially during dry spells.
 
But soggy soil can cause root rot, so make sure your bed drains well.
 

5. Harvest Often to Delay Bolting

Pinching off the outer leaves regularly encourages more growth and delays bolting.
 
The more you harvest, the longer your cilantro will stay productive.
 

Common Mistakes to Avoid When You Plant Cilantro in Minnesota

Even seasoned gardeners make mistakes when they plant cilantro in Minnesota.
 
Here are a few to watch out for:
 

1. Planting Too Late

If you wait until July to plant cilantro in Minnesota, the heat will cause it to bolt before you get a decent harvest.
 
Stick to spring or fall plantings for the best results.
 

2. Not Replanting

Cilantro is a one-and-done kind of plant.
 
Once it bolts, the leaves turn bitter and the plant is done.
 
That’s why succession planting is so important when you plant cilantro in Minnesota.
 

3. Ignoring the Weather

Minnesota weather can be unpredictable.
 
A late frost or an early heat wave can throw off your plans.
 
Keep an eye on the forecast and be ready to cover your plants if needed.
 

So, When to Plant Cilantro in Minnesota?

The best time to plant cilantro in Minnesota is mid-May through early June for spring crops, and late August through early September for fall crops.
 
Cilantro thrives in cool weather, so timing is everything if you want to avoid bolting.
 
By planting in succession and following a few simple tips, you can enjoy fresh cilantro from your Minnesota garden for months.
 
Whether you’re in the Twin Cities or up north near Duluth, knowing when to plant cilantro in Minnesota will help you get the most out of this flavorful herb.
