Watering cilantro


Interested in growing cilantro? Knowing how often to water cilantro plants is an important part of their care.

Overwatering can make the plant susceptible to disease and underwatering can stunt the cilantro plant’s growth, or even kill it.

If you are growing your own cilantro, it’s important to keep in mind how to properly care for your plant.

In this article, we’ll be taking a look at how often to water your cilantro plant. The answer will vary depending on a bunch of factors. We’ll analyze those factors and how they affect your cilantro plant’s watering needs.

How often to water cilantro plants

When it comes to how often to water cilantro plants, the answer depends on a variety of factors. For example, is the cilantro plant planted in a pot or in the ground? Is it in direct sunlight or does it only get a partial day of direct sunlight? What has the weather been like recently?

Generally speaking, the best way to determine how often to water your cilantro plant is to check the top half-inch of soil for dampness. As a rule of thumb, if it’s dried out, give the cilantro plant some water. If it’s still damp or moist in the top half-inch, then no need to water the cilantro plant.

Watering cilantro seedlings

When it comes to how often to water cilantro seedlings, you want to make sure you give your young cilantro plant the water it needs for its early growth.

Sometimes cilantro plant seedlings are grown in bunches. These may soak up moisture faster, so keep tabs on the dampness of the soil for these seedlings.

It’s best to water them lightly more frequently than watering them a lot less frequently.

Seedlings are more susceptible to “drowning” when they are overwatered. Too much water at once can also cause the plant to uproot itself, as soil washes away easier when the plant doesn’t have a solid root structure in place.

Plan on watering your cilantro seedlings every few days, or even daily. Keep an eye on the surface level dryness of the soil, and give the seedlings a sprinkle if it doesn’t look moist.

Cilantro seedlings are faster to show it if they don’t have enough water, so if the plant is wilting and the soil is dry, not enough water is probably the problem.

Watering an established cilantro plant

Established cilantro plants should be watered when the top half-inch of soil is dry. Below are specific growing scenarios and information on how often to water the cilantro plant for each.

When to water cilantro that is planted outside

Cilantro planted outside is often healthier, as there’s more chance of direct sunlight, and airflow generally helps to protect it against disease.

Plan on watering your established cilantro plant a few times a week when it’s planted outside. If you’re not sure whether it needs to be watered, you can check if the surface level soil is moist, or if the cilantro plant is wilting.

Overall, cilantro needs moist soil so as long as the ground-level soil is moist, you probably don’t need to water the cilantro plant.

When to water cilantro that is planted inside

Cilantro plants that are planted inside may not need as much water, as direct sunlight is normally not available. Be extra careful that you aren’t overwatering the cilantro plant inside.

If the cilantro plant is wilting, that could be a sign that it is under or over-watered. Keep track of how moist the soil is to know the difference before watering the cilantro plant more.

When to water cilantro planted in the landscape

Cilantro that is planted in the landscape is able to pull up some moisture from the ground, so it won’t need to be watered as much as cilantro plants are grown in a container.

When to water cilantro planted in containers

As mentioned previously, cilantro that is planted in a container will need to be watered more frequently since they don’t have natural water in the ground as a source of hydration.

Things to consider

There are numerous factors to consider when determining how often to water your cilantro plant. Factors like weather, sunlight, the season of the year, and spacing all play a role.


Spring weather is generally rainier in some areas, so you may not need to water your cilantro plant much. Be careful that you don’t overwater your cilantro plant in a season with a lot of rain.

Sunlight exposure

Most cilantro plant varieties grow great in full sunlight, but in the heat of the summer, you’ll need to keep these plants watered well. 

Cilantro plants that are grown in full sun will dry out fast, especially if they are getting direct sunlight during the noon of the day.

Keeping the cilantro plant well watered in these seasons ensures that they’ll be able to produce healthy new shoots of fresh cilantro in the future.


Depending on the season, you may not need to water your cilantro plant as much. In the fall, when the cilantro plant is more established and the cooler weather sets in, you may only need to water the cilantro plant once a week.


Cilantro plants that are planted close together will compete for the same water, and as a result, you’ll need to water them more.

Tips for watering your cilantro plant

Here are some tips for watering your cilantro plants.

Your cilantro plant may wilt with too much water or too little

Keep in mind that a cilantro plant that is wilting does not necessarily always need water. Sometimes cilantro plants wilt when they have too much water.

Always check the soil dryness to determine if you should give the cilantro plant some water.

It may not be a watering problem, but a fertilizing problem

If the plant is wilting or looking yellow, it may not be your watering that is the problem. You may want to check the fertilizer level of the soil it’s planted in to see if that’s the problem.

Make sure your pot has adequate draining

If you are planting your cilantro in a pot, it’s very important that the pot has proper drainage. cilantro is susceptible to root rot if water does not drain through the soil, so well-drained soil is essential.


If the cilantro plant needs watering a lot, you may want to re-pot the plant so that it has more soil to spread its roots in.

Watering your cilantro plant recap

In conclusion, there are many factors that will affect how often you’ll need to water your cilantro plant. The best and most simple thing to do is check the moisture level in the top half-inch of soil to determine if it needs some water.
