How often water basil plants is a question that would be nagging at the back of your mind, then you have found the relevant article. Basil is a plant of the Lamiaceae family that prefers a moist environment and needs approximately one inch of water every week to maintain healthy root growth and moist soil.

Frequency of Watering Basil

The watering frequency of the basil is going to be the topic of discussion in this in-depth article. As you continue reading, we will also provide you with some watering tips and suggestions to ensure that an adequate quantity of moisture is present for the plant, so read on.

How Often Should Basil Plants Be Watered?

⚡️ Basil plants should be watered once or twice every week with one to two inches of water when they are grown outdoors. When you are growing the plant indoors, you should water it with one inch of water every week, which will be sufficient for its growth. 



Watering Basil Regularly

The reason why you should be very specific when it comes to the schedule of the water is that this plant requires fairly consistent and mildly moist soil to thrive in; however, this level and frequency depend on factors like the environment and basil’s container.

– Growing Indoor 

In regard to how often water basil indoors, know that you will need to hydrate indoor basil once every three to five days, depending on the type of heater or air conditioning that is used inside the home, the humidity level, the size of the potted basil plant in the home environment it is growing in, and the position of the herb plant within the house.

Basil Growing Indoor 

What you should know is that when you grow basil inside homes, the plant still needs enough exposure and sunlight at all stages, including the leaves and the roots. Thus, the rate of water evaporation from the soil depends on the placement of the plant and the exposure to sunlight, especially if the weather is warmer.

The general recommendation is to water it once a week and then move it closer to the windows so that it may receive the maximum amount of sunlight. Moreover, the drain holes need to be of an acceptable size so that any extra water that may have built up around it can escape via them.

This is very important since the plant doesn’t appreciate and feel fully nurtured when there is too much moisture in the air or, if you are over-watering basil, it can hurt the roots and create substantial damage.

– Outdoor Growing

Outdoor basil leaves would require thorough watering at least twice a week. Ensure the water drains out of the holes in the container to prevent the roots from becoming too shallow or the soil dry. Remember that the plant will have a series of dry soil, because the weather is warmer outside, then, the water will evaporate much faster, and this is why this method requires more watering in a week.

Furthermore, when the weather is cooler or there is rainfall, you should reduce the frequency of basil watering to about once every week. In short, it will prevent overwatered basil and ensure that they thrive well.

What Are the Factors To Consider When Watering Basil? 

The factor to consider when watering your basil plant are the season change, The larger the pot, the more soil which means more watering.

The seedlings you have placed, and the type of pot, the type of soil you have used and zone it grows in.

– Season Change

Seasonal changes also impact the frequency of watering. This is why when you try to observe at how to water basil indoors, we crucially pay attention to not only the conditions inside the home, but also the increase in summers and the rising chills and frost conditions of the winters. 

Seasonal Change for Basil

Which means that you would have to pay a little more attention to your basil houseplant as per the seasonal change by increasing in summers and scaling back in winters. When you feel that there is the need to adjust the frequency, the first thing you should do is to test the moisture content to know how the soil feels with your fingers to ensure that it continues to be healthy. 

If you observe that the plant is drying out more regularly, you should increase the frequency with which you water it. In general, you may be shifting your use between air conditioners and heaters which tend to dry out the air faster in variable degrees; hence, seasonal changes may call for increased watering frequency.

On the other hand, when it is spring time, and the weather is changing from winter to spring, then think about how you should start gradually including another time in the week to add more water. This would establish the growth and the plant would become in a better state, because as the weather changes, the warmth starts to dry up the soil, hence you change the pace of the schedule. 

– Larger Pot

If your basil is grown in a large pot at least ten inches across, you will need to water it less frequently than if grown in a little container, provided you are thoroughly watering and flushing the soil.

Basil Growing in a Larger Pot

This is the type of herb that would begin to bloom exceptionally well when grown in larger pots because the increased soil volume enables superior root development and is better equipped to retain moisture readily. Growing basil in larger pots also makes it easier to harvest the leaves and stems of the plant, and the soil would be better aerated, and not compact, when the pot is large enough. 

Do note that larger pots produce many more leaves as the roots can spread out; absorbing nourishment from the soil and providing enough water to keep it thoroughly hydrated is essential. When taking care of a basil plant, it is important to keep the soil at an even and consistent level of moisture at all times, preventing it from becoming either too wet or remaining dry soil.

– The Seedlings

Want to know how often to water basil seeds? Seedlings require watering once every two days through misting or hydrating from the bottom. You must be careful and make sure how you would keep a close eye when you plant basil and, thus, should not overwater it, this will start to promote different diseases and weaken the plant. 

The Seedlings of Basil

It is better to use smaller volumes of water at frequent intervals instead of watering them in one go. This is to be diligently practiced irrespective of whether the basil planted is in the garden or if the seeds have just been sown in a plug tray until they become hardier.

After planting basil, give the soil a light soaking with water to hasten the process of germination. At this stage, the roots are still very young, and as a consequence, the entire plant is susceptible to being uprooted; thus, it is probably best to water the seeds from the bottom when you are starting them in a plug tray. 

On the other hand, you also shouldn’t aim to risk the seed you planted blowing away in the wind. When the seedlings are a little bigger, you can stretch the time between watering sessions to about once every three days.

– Quality of Pot

The amount of time between watering sessions is also heavily influenced by the type of material and components that make up the container itself. When you have a clay container with microscopic holes are more porous, and as a result, they lose their moisture more quickly, requiring more frequent replenishment with water. 

Quality of Pot for Basil

On the other hand, ceramic pots have a greater capacity for retaining water for extended periods, which means that the plants grown in them will require less frequent watering. However, before you water your basil plants, which is when you shouldn’t let the soil become so dry that the leaves begin to droop.

In addition, if you intend to use your pot outside or inside, you should verify that it possesses a drainage hole in the base of the container. You don’t want your plant to die because a severe thunderstorm flooded its container and caused it to suffocate on stagnant water.

The best technique to determine whether or not the plant needs to be watered is to dig your fingers into the soil to get a sense of how much moisture is already there. You should give the basil a good soak if it seems to have only negligible moisture; nevertheless, in this case, you should avoid making it overly soggy by giving it too much water.

– Garden Soil Type Used

The type of garden soil used too greatly determines the amount of water you would have to add to the pot. This is a plant that loves well-drained and light soil as the water is seldom held within in such types. 

Garden Soil Type for Basil

On the contrary, loamy soils retail far too much water than required and the rate of water evaporation is much slower, so watering frequency in such cases maybe once every three to four days.

In addition to this, if you have been experiencing persistent downpours, you may be able to go without watering it for a more extended amount of time, so that the plant would start to establish itself in this soil.

Another aspect that you should focus on is the presence of different material that would be added in the soil might lead it to either retain or lose its ability to hold water, depending on the nature of the addition. Peat-based potting mixes are more successful in promoting aeration and, as a result, draining away excess moisture than clayey or loamy soils. 

You may need to water your plants more regularly if the soil in your garden is sandy because sandy soils drain more quickly than other types of soil. As a consequence of this, if you want to stop the moisture in your soil from evaporating, you should mulch the space around your basil plants.

– The Growing Stage

If you live in an arid zone with dry winds, water more frequently to ensure you give it the desired and optimal plant care, and the stage that the plant is in would also be another determiner. Always ensure you water the basil in the first half of the morning to prevent the plant from dehydrating throughout the potentially warm and dry day, when it has become mature enough. 

If growing your basil outdoors, you must place it in an ideal environment with moderate humidity between 40 and 60 percent and a temperature range between 50 and 80 degrees Fahrenheit. 


1. Is It Possible to Overwater Basil?

Yes, it is possible that you could be overwatering basil plants if the drain holes are not proper or the texture of the soil is dense. The soil in which basil is grown needs to be kept moist at all times, but it should not be allowed to become completely saturated. As a result, the basil plant must be grown in soil with a high drainage capacity or in pots with suitable drainage holes. 

Excess water will cause the soil to deplete its nutrients and may also cause the roots to rot. You will also notice that the basil leaves turn yellow or brown; the plant may start to droop and eventually die. If you have inadvertently overwatered your basil plant, all you need to do is hold off on giving it more water until the soil has become dry.

2. What Does Basil Look Like If It Is Under-Watered?

If the soil appears cracked or is pulling away from the sides of the container, this is a sign that the soil has become overly dry.

Under Watered Basil

The plant will have a somewhat limp appearance, with leaves that are wilting or drooping, pointing downward and either turning yellow or not being as bright green as they should be. This will cause the plant to appear as a less healthy basil than it is.

3. How Often To Water Herbs?

Thyme and rosemary are herbs similar to sweet basil or Thai basil and require once a week of hydration. So if you want to understand how often to water rosemary or how often to water thyme, know that you should water just keep the soil lightly moist at all times.

4. Does Basil Require Direct Sunlight?

Basil is a herb that grows best in tropical climates, where the sun and heat are abundant. So does basil need full sun? Yes, of course, it does. It should be placed in an area exposed to the sun for six to eight hours per day. How much sunlight basil needs depends on the size of the plant and the stage of development, with larger plants requiring adequate morning sun and the developing seedlings doing well under some afternoon shade.


In this article, you read about how often to water basil plants.

Here is a quick summary of the learning in this guide. 

  • Basil plants prefer to be watered once a week; however, this greatly depends on the season the soil, the temperate zone and the soil conditions of the plant.
  • The type of container too plays a crucial role in determining the frequency. Where a large pot with thorough watering requires less frequent watering, small pots evaporate water much faster, requiring regular watering.
  • The soil conditions, too, matter a lot in determining the frequency. Sandy, light and aerated soils provide better drainage; hence you will need to up the frequency to meet the moisture requirements of the plant. On the other hand, clayey and loamy soils retain more moisture; thus, water is less frequent.
  • Consequently, if you want to control the moisture in your soil, a great idea is to mulch the area around the base of the stem to retain it for the plant’s health.

You are now aware of how frequently basil should be watered and the plant’s appropriate moisture levels. You should therefore go ahead and give the plant the proper plant care it needs to ensure that you have a herb that is thriving in your home.
