Yes, cilantro can be grown in water, and it’s actually one of the easiest herbs to propagate this way.
If you’ve ever wondered “can cilantro be grown in water?” the short answer is absolutely yes, as long as you start with fresh cuttings or healthy stems.
You don’t need soil, you don’t need a garden bed, and you don’t even need a green thumb to get started.
In this post, we’ll walk through exactly how cilantro can be grown in water, what you need to know about rooting, and how to keep your plant thriving for weeks.
Let’s get into it.
Why Cilantro Can Be Grown in Water
Cilantro can be grown in water because the plant is capable of developing new roots from its stem nodes when submerged.
Here’s why this method works so well:
1. Cilantro Roots Easily from Cuttings
The main reason cilantro can be grown in water is that it roots readily from stem cuttings.
Unlike some herbs that need special hormones or rooting powder, cilantro produces new roots on its own when given the right conditions.
This makes growing cilantro in water a simple, low-maintenance project for anyone.
2. Water Provides Constant Hydration
When you grow cilantro in water, the stems stay consistently hydrated.
That steady moisture encourages the plant to focus energy on root development instead of searching for water in dry soil.
It’s a bit like giving your cilantro a head start on survival.
3. No Soil Means No Soil-Borne Problems
Growing cilantro in water also sidesteps common soil issues like fungus gnats, damping off, and soil-borne diseases.
Since there’s no dirt involved, your cilantro can be grown in water indoors without worrying about pests lurking in potting mix.
That’s a big plus for anyone who wants a clean, mess-free herb garden.
4. It Works Year-Round Indoors
Can cilantro be grown in water during winter or in a tiny apartment?
Yes, and this is where the water method really shines.
Because you can grow cilantro in water on a windowsill or under a grow light, you’re not limited by seasons or outdoor space.
That means fresh cilantro is possible even when it’s freezing outside.
How to Grow Cilantro in Water Step by Step
If you want to know how cilantro can be grown in water successfully, follow these simple steps.
1. Start with Healthy Cuttings
Begin by snipping stems from a mature cilantro plant.
Choose pieces that are about 4 to 6 inches long and have at least a few leaf nodes along the stem.
Make your cut just below a node, since that’s where new roots will emerge when you grow cilantro in water.
Remove the lower leaves so they won’t sit in the water and rot.
2. Use a Clean Glass or Jar
Place your cuttings in a clean glass or jar filled with fresh water.
Only the bottom inch or two of the stems should be submerged.
If too much of the stem sits in water, it can turn soft and mushy, which will stop cilantro from being grown in water effectively.
3. Change the Water Every Few Days
Fresh water is essential when cilantro is grown in water.
Swap it out every two to three days to keep it oxygenated and free of bacteria.
Cloudy water is a sign that it’s time for a change, and ignoring it can cause your cuttings to rot before roots form.
Tips for Keeping Cilantro Thriving in Water
Once roots appear, your cilantro is technically established, but that doesn’t mean the work is done.
Here’s how to keep cilantro growing in water for as long as possible.
1. Give It Plenty of Bright, Indirect Light
Cilantro grown in water needs bright but indirect sunlight to produce healthy leaves.
A sunny windowsill works great, but harsh afternoon sun can scorch the leaves.
If natural light is limited, a simple LED grow light for a few hours a day keeps cilantro grown in water happy and productive.
2. Add a Drop of Liquid Fertilizer
Water alone doesn’t provide nutrients, so after a couple of weeks, your cilantro may start to look pale.
Add a very diluted drop of liquid houseplant fertilizer to the water every few weeks.
This gives cilantro grown in water the nutrients it needs to keep producing flavorful leaves.
3. Harvest from the Top
When harvesting cilantro that’s grown in water, always snip from the top and leave the lower leaves alone.
This encourages bushier growth and keeps the plant from going to seed too quickly.
Regular harvesting also keeps cilantro grown in water from becoming leggy and weak.
4. Transplant to Soil if You Want a Bigger Plant
Cilantro can be grown in water indefinitely, but it won’t reach its full size that way.
If you want a larger, longer-lasting plant, transplant your rooted cuttings into potting soil after a few weeks.
This gives cilantro grown in water a chance to spread its roots and produce even more leaves.
So, Can Cilantro Be Grown in Water?
Cilantro can be grown in water, and it’s a fun, simple way to keep fresh herbs on hand without any soil.
Just start with healthy cuttings, keep the water clean, and give your plant bright light and the occasional nutrient boost.
Whether you’re a seasoned gardener or a total beginner, growing cilantro in water is a rewarding project that delivers fresh flavor right from your windowsill.
Give it a try, and you’ll never have to buy sad, wilted cilantro from the store again.
