How Do You Grow Cilantro Indoors In Water

You can grow cilantro indoors in water, and it’s one of the easiest kitchen projects you’ll ever try.
 
All you need is a fresh bunch of cilantro, a glass jar, and a little patience.
 
The stems will sprout new roots in about a week, giving you a steady supply of fresh leaves right on your windowsill.
 
In this post, we’ll walk through exactly how to grow cilantro indoors in water, from choosing the right stems to harvesting your first batch.
 
Let’s dig in.
 

Why You Can Grow Cilantro Indoors in Water

Growing cilantro indoors in water works because cilantro is a surprisingly resilient herb.
 
Here’s why this method is so popular:
 

1. Cilantro Roots Easily From Stem Cuttings

The main reason you can grow cilantro indoors in water is that the plant roots readily from stem cuttings.
 
Cilantro stems contain nodes, which are the little bumps where leaves attach.
 
Those nodes are packed with cells that can turn into roots when they touch water.
 
This means you don’t need seeds or soil to start a new cilantro plant indoors.
 
You just need a healthy stem and a bit of clean water.
 

2. Water Delivers Everything the Cuttings Need

When you grow cilantro indoors in water, the cuttings get moisture and dissolved oxygen directly through their stems.
 
As long as you change the water every couple of days, the cuttings stay hydrated and healthy.
 
That’s why growing cilantro in water is such a low-maintenance way to keep fresh herbs around.
 
Once roots form, they’ll absorb nutrients from the water, though a tiny boost of liquid fertilizer helps them thrive.
 

3. Cilantro Grows Fast Indoors

Cilantro is a quick grower, so you won’t be waiting long to see progress.
 
New roots usually appear within five to seven days when you grow cilantro indoors in water.
 
Fresh leaves start unfurling shortly after that.
 
Within three to four weeks, you’ll have a mini cilantro garden sitting in your kitchen.
 

How to Grow Cilantro Indoors in Water Step by Step

Here’s the simple process for growing cilantro indoors in water:
 

1. Pick the Right Stems

Start with a fresh bunch of cilantro from the grocery store or a friend’s garden.
 
Choose stems that are bright green, firm, and free of yellowing or wilting leaves.
 
Cut each stem about two to three inches below the leaves, right above a node.
 
This is the spot where roots will emerge when you grow cilantro indoors in water.
 

2. Strip the Lower Leaves

Remove any leaves that sit below the waterline once the stems are in the jar.
 
Leaves left in water will rot and turn the water cloudy, which can kill your cuttings.
 
Only the bare stem should touch the water when you grow cilantro indoors in water.
 

3. Place Stems in a Glass Jar

Fill a clean glass jar with about two inches of fresh, room-temperature water.
 
Set the cilantro stems in the jar so the nodes are submerged but the leaves stay dry.
 
If the stems are top-heavy, a narrow jar or a bit of plastic wrap over the top will hold them upright.
 

4. Find a Bright Spot

Place the jar on a sunny windowsill where it gets four to six hours of indirect light daily.
 
Direct, harsh sun can scorch the leaves, so a spot with filtered light is ideal when you grow cilantro indoors in water.
 
A kitchen windowsill is often perfect for growing cilantro indoors in water.
 

5. Change the Water Every Few Days

Swap out the water every two to three days to keep it oxygenated and bacteria-free.
 
Rinse the stems gently and refill the jar with fresh water.
 
This single habit is the biggest secret to successfully growing cilantro indoors in water.
 

Tips for Growing Cilantro Indoors in Water

A few extra tricks will keep your water-grown cilantro happy:
 

1. Add a Drop of Liquid Fertilizer

Once roots are an inch or two long, add a diluted drop of liquid houseplant fertilizer to the water every few weeks.
 
This gives your cilantro the nutrients it would normally pull from soil.
 
Just don’t overdo it, or you’ll burn the roots when you grow cilantro indoors in water.
 

2. Harvest Often

Snip outer leaves regularly to encourage bushy growth.
 
Never take more than a third of the plant at once.
 
Frequent harvesting keeps your cilantro productive and delays bolting, which happens fast in warm indoor air.
 

3. Watch for Root Rot

If the water smells sour or the roots turn brown and mushy, root rot has set in.
 
Trim the damaged roots and start fresh with clean water.
 
Good airflow and regular water changes prevent this problem when growing cilantro indoors in water.
 

4. Start New Cuttings Every Few Weeks

Cilantro in water has a limited lifespan, usually a couple of months.
 
Start a new batch of cuttings every few weeks so you always have fresh cilantro on hand indoors.
 
That way, your indoor cilantro in water supply never runs dry.
 

So, How Do You Grow Cilantro Indoors in Water?

You grow cilantro indoors in water by cutting healthy stems below a node, stripping the lower leaves, and placing them in a jar of fresh water on a bright windowsill.
 
Change the water every few days, add a touch of fertilizer once roots appear, and harvest often.
 
It’s a simple, nearly free way to keep fresh cilantro growing indoors in water all year round.
 
Give it a try this week, and you’ll be snipping fresh leaves for tacos and soups before you know it.
