Cilantro cuttings will root in water.
Yes, you can take a fresh sprig from a bunch of store-bought cilantro, drop it in a glass of tap water, and watch roots appear within about a week.
This works because cilantro is an herb that roots easily from stem cuttings, especially when the cutting is taken from a healthy, vibrant plant.
So if you’ve ever wondered will cilantro cuttings root in water, the short answer is a resounding yes.
In this post, we’ll go over why cilantro cuttings root in water, how to do it step by step, and what to expect once those roots start forming.
Let’s dig in.
Why Cilantro Cuttings Root in Water
Cilantro cuttings root in water because the plant has a natural ability to produce new roots from stem tissue.
Here’s what’s happening under the surface.
1. Cilantro Has Fast-Growing Root Nodes
Along the stems of cilantro, there are tiny growth points called nodes.
These nodes are where leaves and branches normally emerge.
When a cilantro cutting sits in water, those same nodes switch gears and start producing roots instead.
That’s why a cilantro cutting will root in water so reliably compared to many other plants.
2. Water Keeps the Cutting Hydrated
A cutting has no roots yet, so it can’t pull moisture from soil.
Submerging the stem in water solves that problem instantly.
The cut end and the nodes absorb water directly, which keeps the cilantro cutting alive long enough to grow new roots.
Without that hydration, the cutting would wilt and die before rooting ever began.
3. Cilantro Is a Soft-Stemmed Herb
Soft-stemmed herbs like cilantro, basil, and mint root faster in water than woody plants.
Their stems are packed with cells that can quickly transform into root tissue.
This is exactly why cilantro cuttings root in water within a week or so, while a rose cutting might take a month or more.
4. No Soil Means No Rooting Hormone Needed
You don’t need rooting powder or gel for cilantro.
The plant produces its own rooting hormones naturally at the cut site.
Water simply gives those hormones a clean, moist environment to do their job, which is why cilantro cuttings root in water with almost no effort.
How to Root Cilantro Cuttings in Water
Getting cilantro cuttings to root in water is about as simple as it gets.
Here’s the process.
1. Take a Healthy Cutting
Snip a 4 to 6-inch stem just below a node using clean scissors or pruners.
Pick a stem that’s green, firm, and free of flowers, since flowering stems put energy into seed production instead of rooting.
2. Strip the Lower Leaves
Remove the leaves from the bottom 2 to 3 inches of the stem.
Any leaves left underwater will rot, which turns the water murky and can kill your cilantro cutting before it roots.
3. Place It in a Glass of Water
Put the cutting in a clean glass or jar filled with room-temperature water.
Make sure at least one node is submerged, since that’s where the roots will emerge.
4. Change the Water Every Few Days
Fresh water keeps oxygen levels up and discourages bacteria.
Swap it out every 2 to 3 days, and you’ll see little white roots poking out within 7 to 14 days.
5. Keep It in Bright, Indirect Light
Place the glass on a sunny windowsill, but out of harsh direct sun.
Warmth and light speed up the process, so cilantro cuttings root in water fastest in a bright, cozy spot.
What to Do After Cilantro Cuttings Root in Water
Once your cilantro cuttings have rooted in water, you’ve got options.
1. Keep Them in Water Short-Term
You can leave rooted cilantro in water for a few weeks and snip leaves as needed.
Just keep changing the water, and the plant will stay productive for a while.
2. Transplant Into Soil
For a longer-lasting plant, move your rooted cilantro cutting into a pot with well-draining potting mix.
Water it well for the first week and keep it out of direct sun while it adjusts.
Cilantro cuttings that rooted in water usually take to soil without much fuss.
3. Watch for Bolting
Cilantro is a cool-season herb, so it bolts quickly in heat.
If your rooted cutting sends up a tall flower stalk, the leaves will turn bitter.
Pinch off flower buds to keep the plant producing tasty foliage for longer.
So, Will Cilantro Cuttings Root in Water?
Cilantro cuttings will root in water, and they do it fast.
All it takes is a healthy stem, a clean glass, and a fresh change of water every couple of days.
Within one to two weeks, you’ll have roots, and within a month, you’ll have a fresh supply of cilantro growing right on your windowsill.
So the next time you’ve got leftover cilantro from the grocery store, don’t toss those stems.
Root them in water instead and enjoy free cilantro for weeks to come.
