How to Propagate Cilantro in Water for Fresh Herbs All Year
Cilantro, unlike many other herbs, is best used fresh. If you regularly cook with cilantro, you know that keeping a supply of it on hand can be tricky because cilantro is a delicate herb. A bunch of cilantro bought at....

the grocery store, even if stored properly in water in the fridge, starts looking rather sad after a few days.
Fortunately, there is a way to extend the life of the cilantro you buy at the grocery store—by propagating it. You can either grow more cilantro leaves (which does not require pots and potting soil) or take it one step further and create new cilantro plants from the stems.
Here’s how to propagate cilantro so you never have to run to the grocery store for it again.
How to Propagate Cilantro in Water
Separate the cilantro bunch and sort out any weak stems (use those for cooking).
For each strong stem, cut all the outer leaves except the center leaves with clean, disinfected scissors. If there are tiny leaves growing from the center of the stem, leave them intact.
Put the stems in a clean jar and add two to three inches of room-temperature tap water—just enough so that the base of the stems is immersed in water.
Place the jar in a place with bright, indirect light where the temperature is around 60-70°F.
Change the water every day or two.
Leaf growth should start after a few days. Harvest the new leaves as desired using sharp scissors.
Chances of Dulled Flavor
As easy and convenient as it is, cilantro that is propagated in water will produce fresh leaves for you to harvest but it won’t grow as vigorously as when it is planted in soil. The taste of the leaves also tends to be weaker and not as aromatic as cilantro grown in a proper growing medium.

Cilantro Propagation Tips
Picking cilantro: Only use cilantro that looks healthy and is as fresh as possible. Look for cilantro that still has some of the white roots attached—the more roots that are on each stem, the better. Don’t use stems that are wilted or have any signs of disease such as spotting.
Keeping it clean: To avoid bacterial growth, keep the jar and the water clean. It is also a good idea to sanitize the scissors by wiping them with rubbing alcohol.
Safety precautions: If your tap water is chlorinated, let it sit for a day to allow the chlorine to evaporate before using.
Preventative care: Do not immerse the cuttings in water—they will rot. Only the base of the stems should be under water, never the leaves.
Signs of problems: Slime forming around the stems or roots is a sign of bacteria. Change the water immediately and rinse the stems and roots under running water. If the problem persists, start again with fresh cilantro.
Signs of exhaustion: If leaf growth weakens or stops after a few weeks, the stems have given their all. Discard them and start with a fresh bunch of cilantro.
Signs of vitality: However, if the stems have developed lots of roots about 1 inch in length, you can extend the life of your cilantro even further by planting it in a pot filled with well-draining all-purpose potting mix.
Best placement: Cilantro needs light to grow but avoid harsh, direct sunlight. If your kitchen gets strong midday or afternoon sun, place the jar a couple of feet away from the window.
Best temperature: Keep the jar away from heat sources. Cilantro grows best in temperatures between 50-85°F.
Why Propagate Cilantro in Water?
Propagating cilantro in water saves you a trip to the grocery store, especially if you only need a small amount of cilantro at any given time, which is what many recipes call for.
The method is easy, cheap, and requires virtually no equipment or tools. Even for seasoned gardeners, it’s an attractive way to get their hands on fresh cilantro when it’s too cold to grow it outside. Propagation of stem cuttings in water is also much faster than starting cilantro from seed, which takes 40 to 70 days.
