What To Do When Cilantro Starts Flowering

When cilantro starts flowering, you can either let it bloom and collect the seeds or take steps to keep the leaves coming.
 
Cilantro flowering is a natural part of the plant’s life cycle, but it does signal a shift in flavor and leaf production.
 
If you’ve been asking what to do when cilantro starts flowering, you have a few solid options depending on what you want from your garden.
 
In this post, we’ll walk through what to do when cilantro starts flowering, why it happens, and how to make the most of it.
 
Let’s dig in.
 

What to Do When Cilantro Starts Flowering

When cilantro starts flowering, the plant is bolting, which means it’s redirecting energy from leaf growth to seed production.
 
The good news is that flowering cilantro isn’t ruined, it’s just entering a new phase.
 
Here’s what to do when cilantro starts flowering so you get the best outcome.
 

1. Harvest the Leaves Immediately

The first thing to do when cilantro starts flowering is to harvest as many leaves as you can right away.
 
Once the plant bolts, the leaves that remain tend to turn bitter and lose that fresh citrusy flavor.
 
So grab your scissors and snip what’s left before the flowers fully open.
 

2. Let Some Plants Flower for Seeds

If you want coriander seeds, letting cilantro flower is exactly what you should do.
 
The flowers turn into seed heads, and those seeds are the coriander spice you buy at the store.
 
So when cilantro starts flowering, consider leaving a few plants alone to produce seeds.
 

3. Save the Seeds for Next Season

After the flowers fade, green seed pods form and eventually turn brown.
 
Collect those seeds, dry them, and store them for planting or cooking.
 
This is one of the best ways to handle cilantro flowering if you want free seeds for next year.
 

Why Cilantro Starts Flowering in the First Place

Cilantro starts flowering because of stress, and that stress usually comes from heat.
 
When temperatures climb above 75°F, cilantro bolts fast.
 
Longer daylight hours also push cilantro flowering along.
 
And if the plant is root-bound or short on water, that speeds things up too.
 

1. Heat Triggers Bolting

Heat is the number one reason cilantro starts flowering.
 
Cilantro is a cool-season herb, so when summer heat hits, the plant panics and rushes to set seed.
 
That’s why cilantro flowering happens so quickly in hot climates.
 

2. Day Length Plays a Role

As days get longer, cilantro gets the signal to flower.
 
This is why cilantro flowering often shows up in late spring and early summer.
 

3. Stress From Water or Roots

Dry soil and cramped roots stress cilantro out.
 
And stressed cilantro starts flowering sooner than you’d like.
 

How to Slow Down Cilantro Flowering

You can’t stop cilantro flowering forever, but you can delay it.
 
Here’s how to keep cilantro from flowering too fast.
 

1. Plant at the Right Time

Plant cilantro in early spring or late summer when the weather is cool.
 
This timing helps you avoid the heat that triggers cilantro flowering.
 

2. Give It Shade

Afternoon shade keeps cilantro cooler and slows bolting.
 
A little shade goes a long way when you’re trying to prevent cilantro flowering.
 

3. Water Consistently

Keep the soil evenly moist so the plant doesn’t stress.
 
Consistent moisture is one of the simplest ways to delay cilantro flowering.
 

4. Harvest Often

Regular trimming encourages leaf growth and delays cilantro flowering.
 
So snip those leaves often to keep the plant in leaf mode.
 

So, What to Do When Cilantro Starts Flowering?

When cilantro starts flowering, you can harvest the remaining leaves, let the plant go to seed, or save those seeds for later.
 
Cilantro flowering isn’t a failure, it’s just the plant doing what comes naturally.
 
Whether you fight it or embrace it, knowing what to do when cilantro starts flowering helps you get more from your garden.
 
So next time your cilantro starts flowering, you’ll know exactly how to handle it.
