When To Plant Cilantro In New England

The best time to plant cilantro in New England is in the cool seasons of spring and fall, not the heat of summer.
 
Cilantro loves chilly weather, so timing your planting around New England’s unpredictable temperature swings is the real trick to getting a steady harvest.
 
If you’ve been wondering when to plant cilantro in New England, the short answer is early spring and late summer, with a little extra strategy for keeping it going all season.
 
Cilantro bolts fast when the heat kicks in, so understanding your local climate is everything.
 
In this post, we’ll walk through exactly when to plant cilantro in New England, how to handle its bolt-prone nature, and the best ways to enjoy fresh leaves from spring through fall.
 
Let’s dig in.
 

When to Plant Cilantro in New England

When to plant cilantro in New England comes down to avoiding the heat, which means your two prime windows are early spring and late summer.
 
Timing matters more for cilantro than for almost any other herb you’ll grow here.
 

1. Plant in Early Spring After the Last Frost

The first and best window to plant cilantro in New England is right after your last frost date, usually mid-to-late April in southern New England and early-to-mid May farther north.
 
Cilantro germinates best when soil temperatures sit between 55°F and 70°F, which is exactly what early spring delivers.
 
You can direct sow seeds about two to three weeks before your last expected frost, since cilantro seedlings tolerate a light chill and actually prefer it.
 
This early start lets your plants grow leafy and lush before the summer heat arrives.
 

2. Start Seeds Indoors for a Head Start

If you want a jump on the season, you can plant cilantro seeds indoors about four to six weeks before your last frost.
 
Cilantro has a taproot and hates being transplanted, so use biodegradable pots you can drop straight into the ground.
 
This gives you a head start on the New England growing season without disturbing the roots.
 
Just harden them off gently before setting them outside.
 

3. Plant Again in Late Summer for a Fall Crop

The second great time to plant cilantro in New England is late summer, usually from mid-August through early September.
 
By then the worst of the heat has passed, and the cooling days of fall are perfect for cilantro to thrive.
 
This fall planting often gives you the most tender, flavorful leaves of the entire year.
 
In many New England zones, a fall-planted cilantro will keep producing right up until a hard freeze.
 

Why Cilantro Bolts So Fast in New England Summers

Cilantro bolts, or goes to seed, when temperatures climb above 75°F, which is why summer planting here is so frustrating.
 
Once it bolts, the leaves turn bitter and the plant stops producing the tender foliage you actually want.
 
New England’s hot, humid Julys are the enemy of good cilantro.
 

1. Heat Triggers the Bolt

When cilantro feels prolonged heat, it panics and rushes to set seed before it dies.
 
That’s a survival instinct, not a flaw in your gardening skills.
 
So planting cilantro in New England during peak summer almost always ends in disappointment.
 

2. Choose Slow-Bolt Varieties

If you must plant cilantro in the summer, pick slow-bolt types like ‘Santo’ or ‘Calypso’ that resist bolting longer.
 
These varieties buy you extra weeks of harvest even when the mercury rises.
 
They’re not bulletproof, but they help a lot.
 

3. Use Shade and Succession Planting

Plant cilantro in a spot that gets afternoon shade, and sow new seeds every two to three weeks for a continuous supply.
 
Succession planting is the secret weapon for anyone trying to grow cilantro in New England all season long.
 
Each new sowing replaces the one that’s bolting, so you’re never without fresh leaves.
 

Tips for Growing Cilantro in New England

Once you know when to plant cilantro in New England, a few care tips will keep it productive.
 

1. Give It Rich, Well-Drained Soil

Cilantro grows best in loose, fertile soil with plenty of organic matter and good drainage.
 
Wet, heavy soil rots the roots fast in New England’s rainy springs.
 

2. Keep It Consistently Moist

Water cilantro regularly so the soil stays evenly damp, but never soggy.
 
Dry spells stress the plant and push it to bolt even sooner.
 

3. Harvest Often to Delay Bolting

Snip the outer leaves regularly, and pinch off any flower stalks the moment you see them.
 
Frequent harvesting keeps cilantro in leaf-production mode instead of seed mode.
 

So, When to Plant Cilantro in New England?

The best time to plant cilantro in New England is early spring after the last frost and again in late summer for a fall harvest.
 
Cilantro thrives in cool weather and bolts quickly once summer heat arrives, so timing your planting around those cool windows is the key.
 
Use succession planting, slow-bolt varieties, and afternoon shade to stretch your harvest as far as possible.
 
Get the timing right, and you’ll enjoy fresh, tender cilantro from spring through the first frost.
