Yes, you can regrow cilantro in water, and it’s one of the easiest kitchen projects you can start today.
If you’ve ever wondered “can you regrow cilantro in water?” the answer is a resounding yes.
You can regrow cilantro in water from stem cuttings, and it’s a simple, low-cost way to keep fresh herbs on hand without buying new bunches every week.
All you need is a glass, some water, and a few healthy stems from a fresh bunch of cilantro.
In this post, we’ll cover how to regrow cilantro in water, why it works, the best conditions for success, and common mistakes to avoid.
Let’s get to it.
Why You Can Regrow Cilantro in Water
You can regrow cilantro in water because cilantro stems contain nodes.
These nodes are the little bumps where leaves once grew, and they hold dormant cells capable of developing new roots.
When submerged in water, those cells spring into action and start producing roots within days.
Here’s why this process works so well:
1. Cilantro Stems Root Easily
Cilantro is a fast-growing herb, and its stems are naturally geared for quick rooting.
As long as you cut a healthy stem just below a node, you can regrow cilantro in water without any rooting hormone.
The node is the key, so make sure at least one node sits below the water line.
2. Water Provides Everything Roots Need
Water gives the cutting moisture, oxygen, and a clean medium to sprout roots.
You don’t need soil for this stage because the cutting already has stored energy in its stem.
That stored energy fuels new root growth until the plant is ready for soil, if you choose to transplant it.
3. Cilantro Grows Fast From Cuttings
When you regrow cilantro in water, you can see roots forming in as little as five to seven days.
New green leaves usually appear within two weeks.
That speed makes this project satisfying, especially if you’re new to growing herbs indoors.
How to Regrow Cilantro in Water Step by Step
Learning how to regrow cilantro in water is straightforward.
Just follow these simple steps:
1. Pick Fresh, Healthy Stems
Start with stems from a fresh bunch of cilantro.
Look for firm, green stems with plenty of leaves and at least one visible node.
Avoid stems that are wilted, yellowing, or mushy, because they won’t root well.
2. Cut Just Below a Node
Using clean scissors or a sharp knife, cut the stem about an inch below a node.
Make a diagonal cut, which gives more surface area for water absorption.
Remove any leaves from the bottom of the stem so they don’t rot in the water.
3. Place Stems in a Glass of Water
Put your cuttings in a small glass or jar filled with about two inches of fresh water.
Make sure the node is submerged but the leaves stay above the water line.
Place the glass in a bright spot away from direct, harsh sunlight.
4. Change the Water Every Few Days
Fresh water keeps bacteria and algae from building up.
Change the water every two to three days, and rinse the stems gently as you do.
Clean water is one of the biggest secrets to successfully regrow cilantro in water.
5. Watch for Roots and New Growth
Within a week or so, you’ll notice little white roots emerging from the node.
Soon after, fresh green leaves will start to appear.
At this point, you can either keep growing the cilantro in water or transfer it to soil.
Can You Regrow Cilantro in Water Forever?
Can you regrow cilantro in water and keep it going indefinitely?
Not really, and here’s why.
1. Water Alone Isn’t a Long-Term Solution
Water gives cuttings a strong start, but it doesn’t provide the nutrients that mature cilantro plants need.
Over time, water-grown cilantro will weaken, turn pale, and stop producing new leaves.
That’s why water is best used as a starting method, not a permanent home.
2. Cilantro Is a Short-Lived Herb
Cilantro is an annual, meaning it naturally has a limited lifespan.
Even in perfect soil, cilantro bolts and goes to seed within a few months.
So expecting a single cutting to produce forever just isn’t realistic, no matter how well you regrow cilantro in water.
3. Transfer to Soil for Best Results
Once roots are about one to two inches long, you can move your cilantro into a pot with well-draining soil.
This gives the plant access to nutrients and supports stronger, bushier growth.
Transitioning from water to soil is the best way to enjoy fresh cilantro for weeks instead of days.
Common Mistakes When You Regrow Cilantro in Water
Even though it’s easy, a few missteps can slow you down.
Here’s what to avoid when you regrow cilantro in water:
1. Leaving Leaves Submerged
Leaves sitting in water will rot quickly and cloud the water.
Always strip the lower leaves and keep only the stem and node underwater.
2. Skipping Water Changes
Stale water grows bacteria, and bacteria kills cuttings.
Change the water every couple of days for the healthiest roots.
3. Using Direct Sunlight
Too much direct sun can overheat the glass and stress the cutting.
Bright, indirect light is ideal for helping cilantro thrive in water.
So, Can You Regrow Cilantro in Water?
You can regrow cilantro in water, and it’s a fun, easy way to get fresh herbs from kitchen scraps.
Just cut healthy stems below a node, place them in clean water, and change the water every few days.
Roots appear fast, and you’ll have fresh cilantro leaves in no time.
For long-term growth, move your rooted cuttings into soil so they get the nutrients they need.
Give it a try, and you’ll always have a bit of fresh cilantro ready when you need it.
