How To Fertilize Cilantro

You can fertilize cilantro lightly and regularly to keep those flavorful leaves coming all season long.
 
This herb is a fast grower, and because you’re constantly snipping leaves for tacos, salsa, and soups, it needs a steady supply of nutrients to keep up.
 
If you’ve been wondering how to fertilize cilantro without burning it or making it bolt too soon, you’re in the right place.
 
The good news is that cilantro isn’t a heavy feeder, so it doesn’t need much to thrive.
 
In this post, we’ll walk through how to fertilize cilantro, when to do it, and what to use so you get tender, tasty leaves instead of spindly stems.
 
Let’s dig in.
 

How to Fertilize Cilantro the Right Way

When you fertilize cilantro, the goal is to feed the plant gently without pushing it into quick flowering.
 
Cilantro grows fast, but too much nitrogen or a heavy dose of food can stress it out.
 
Here’s how to get it right:
 

1. Start With Good Soil

Before you even think about how to fertilize cilantro, make sure it’s planted in loose, well-draining soil.
 
Cilantro likes soil that holds a little moisture but never stays soggy.
 
Mixing in some compost before planting gives it a gentle nutrient base so you don’t have to feed as often.
 
That compost also improves soil texture, which helps cilantro roots grow strong.
 

2. Use a Balanced Liquid Fertilizer

A balanced liquid fertilizer diluted to half strength is one of the easiest ways to fertilize cilantro.
 
Look for something like a 10-10-10 or an organic fish emulsion.
 
Mix it at half the recommended dose, then water your cilantro with it every three to four weeks.
 
Liquid fertilizer works fast and gives your cilantro a quick pick-me-up without overwhelming it.
 

3. Feed Lightly and Often

Cilantro does best with small, regular feedings rather than one big dose.
 
If you fertilize cilantro too heavily, you’ll get lots of leafy growth that tastes weak and bolts quickly.
 
Stick to a light feeding every three weeks during the growing season.
 
In hot weather, you can even skip a feeding since cilantro slows down and starts to flower anyway.
 

4. Water Before and After Feeding

Always water your cilantro before you fertilize it.
 
This protects the roots from fertilizer burn and helps the nutrients spread evenly through the soil.
 
After feeding, give it another light watering to wash any fertilizer off the leaves.
 
That simple step makes a big difference when you fertilize cilantro in containers or raised beds.
 

When to Fertilize Cilantro

Timing matters just as much as the fertilizer itself.
 
Here’s when to fertilize cilantro for the best results:
 

1. After Seedlings Have True Leaves

Wait until your cilantro seedlings have at least two sets of true leaves before you fertilize them.
 
At that point, they’re strong enough to handle a diluted feeding.
 
Feeding too early can burn tender roots and stunt growth.
 
Once they’ve settled in, a half-strength liquid feed gives them a healthy start.
 

2. Every 3 to 4 Weeks During Active Growth

During spring and early summer, plan to fertilize cilantro every three to four weeks.
 
This keeps leaves tender and productive while the plant is actively growing.
 
If your cilantro is in rich soil or you mixed in compost at planting, you can stretch it to every four weeks.
 

3. Stop When It Starts to Bolt

Once cilantro sends up a tall stem with lacy flowers, it’s bolting.
 
At this stage, stop fertilizing because the plant is putting its energy into making seeds, not leaves.
 
You can still let it flower for the bees or collect coriander seeds later.
 
But there’s no point trying to fertilize cilantro once it’s past that leafy stage.
 

What to Use to Fertilize Cilantro

You don’t need fancy products to fertilize cilantro well.
 
Here are a few simple options that work great:
 

1. Compost Tea

Compost tea is a mild, organic way to fertilize cilantro without any risk of burning.
 
Steep finished compost in water for a day or two, then strain it and use the liquid to water your plants.
 
It delivers a gentle mix of nutrients and beneficial microbes.
 
This is a great choice if you want to fertilize cilantro naturally.
 

2. Fish Emulsion

Fish emulsion is packed with nitrogen, which cilantro loves for leafy growth.
 
Just dilute it according to the label, usually to half strength, and apply every few weeks.
 
It does have a strong smell, but it fades within a day or two.
 
Used correctly, fish emulsion is one of the best ways to fertilize cilantro in containers.
 

3. Balanced Granular Fertilizer

If you prefer a slow-release option, a balanced granular fertilizer sprinkled around the base works well.
 
Lightly scratch it into the top inch of soil and water it in.
 
This feeds cilantro slowly over several weeks, so you don’t have to remember to mix liquid feeds.
 
Just be careful not to overdo it, since too much can make cilantro bolt faster.
 

So, How to Fertilize Cilantro for the Best Harvest?

To fertilize cilantro properly, feed it lightly with a diluted balanced fertilizer every three to four weeks, starting once seedlings have true leaves.
 
Always water before and after feeding, and stop once the plant begins to bolt.
 
Use compost tea, fish emulsion, or a gentle granular fertilizer to keep leaves tender and flavorful.
 
With just a little care, your cilantro will reward you with plenty of fresh, tasty cuttings all season.
