You can grow cilantro in water only, and it’s one of the easiest herbs to propagate this way.
If you’ve been wondering how to grow cilantro in water only, the good news is that it’s totally doable with just a few stems and a glass of tap water.
Cilantro regrows roots quickly, so you’ll see progress within a week or two.
This method works best with cuttings rather than seeds, since cilantro seeds need soil to sprout properly.
In this post, we’ll walk through exactly how to grow cilantro in water only, step by step, plus tips to keep it thriving.
Let’s dive in.
Why You Can Grow Cilantro in Water Only
Growing cilantro in water only works because cilantro cuttings can develop new roots from their stem nodes.
Here’s why this method is so reliable:
1. Cilantro Roots Easily From Cuttings
Cilantro is a fast-rooting herb, which makes growing cilantro in water only surprisingly simple.
When you snip a healthy stem just below a leaf node, that node contains cells ready to turn into roots.
All they need is moisture and a bit of light to get going.
2. Water Delivers Oxygen and Nutrients
Plain water isn’t just filler, it actually carries dissolved oxygen that roots need to breathe.
As long as you change the water every couple of days, your cilantro cuttings will absorb enough oxygen to grow strong roots.
This is the core reason you can grow cilantro in water only without any soil at all.
3. No Soil Means No Soil Pests
One bonus of growing cilantro in water only is that you skip soil-borne pests like fungus gnats and root aphids.
Your kitchen counter stays clean, and your cilantro stays healthy.
It’s a low-mess way to keep fresh herbs within arm’s reach.
How to Grow Cilantro in Water Only Step by Step
Ready to try it yourself?
Here’s the exact process for how to grow cilantro in water only:
1. Pick Healthy Cilantro Stems
Start with fresh cilantro from the grocery store or a friend’s garden.
Choose stems that are firm, green, and free of yellowing leaves.
Cut each stem about 4 to 6 inches long, making your cut just below a leaf node.
2. Strip the Lower Leaves
Remove any leaves from the bottom 2 inches of each stem.
Those leaves would just rot in the water, which invites bacteria.
You want a clean, bare stem section sitting in the water.
3. Place Stems in a Glass of Water
Put your cuttings in a clean glass or jar filled with room-temperature water.
Make sure the nodes are submerged but the leaves stay above the waterline.
4. Change the Water Every Two Days
Fresh water keeps oxygen levels up and bacteria down.
When you grow cilantro in water only, this step is the one people skip, and it’s why their cuttings fail.
Rinse the stems gently each time you swap the water.
5. Keep It in Bright, Indirect Light
Place your jar on a sunny windowsill, but avoid harsh afternoon sun.
Cilantro loves cool, bright conditions.
Too much heat will make it bolt or wilt.
6. Wait for Roots to Appear
Within 7 to 14 days, you’ll see little white roots sprouting from the nodes.
Once roots reach about 2 inches long, your cilantro is established in water.
At this point, you can keep growing cilantro in water only or transfer it to soil.
Tips to Keep Cilantro Growing in Water Only
To get the most from your water-grown cilantro, keep these pointers in mind:
1. Add a Drop of Liquid Fertilizer
Water alone won’t supply everything cilantro needs long-term.
Once roots form, add a diluted drop of liquid houseplant fertilizer every few weeks.
This keeps leaves green and flavorful when you grow cilantro in water only.
2. Harvest from the Top
Snip outer leaves first and let the center keep growing.
Never take more than a third of the plant at once.
Regular harvesting actually encourages bushier growth.
3. Watch for Algae
If your jar turns green, algae is growing.
Move the jar out of direct sun and scrub it clean.
Algae steals nutrients and can smother young roots.
4. Replace Stems Every Few Weeks
Cilantro grown in water only tends to lose vigor after a month or two.
Take new cuttings from the healthiest stems to keep a fresh supply going.
This way you’ll always have cilantro growing in water only on your counter.
So, Can You Grow Cilantro in Water Only?
You can grow cilantro in water only, and it’s a rewarding project for any home cook.
Cilantro cuttings root quickly in water, need just bright light and regular water changes, and give you fresh leaves for weeks.
Just remember to change the water often, add a little fertilizer once roots form, and start new cuttings before the old ones fade.
With these tips, growing cilantro in water only becomes a simple habit you’ll enjoy all year.
