How Often to Water Lemongrass: Watering Requirements

Lemongrass is one of the easiest plants to grow in your home garden. However, if it gets a little fussy and specific about something, it is the watering requirements that it demands.

Therefore, one thing that most people growing lemongrass are worried about is how often should I water lemongrass. While it requires a careful intervention to water your lemongrass plant, a short answer to the question would be to water the plant every day in summers or if you live in arid regions and reduce the quantity to 3 days a week in temperate environments.

As mentioned earlier, one requires a great deal of knowledge about watering lemongrass right. In the following article, we present a detailed account of how to do so along with some general tips to take care of your lemongrass plant while growing.

Watering Lemongrass

Watering lemongrass is rightly important due to its native relevance. Plants grow to their maximum extent if their natural environment is habituated correctly.

Belonging to the tropical surroundings, lemongrass is very specific about how you water it and usually expects a surplus when compared to other plants.

Another rationale behind the excessive watering needs of the lemongrass plant is the speed at which it grows. During the hot and humid weather conditions, lemongrass shows a drastic and rapid development. For this process, it requires ample amounts of water.

Besides the season, another factor that impacts the watering needs of your lemongrass plant is the soil in which you are growing it. If your bedding soil is sandy and loose, then you are expected to water your plant more frequently than if the soil is loamy or a bit silty.

Loamy soil has properties that allow it to retain significantly high levels of moisture. Consequently, the watering requirements of the plant are reduced.

If you cannot water your plant every day, you can enhance its moisture retaining ability by adding a rich layer prepared with organic mulch. Adding mulch can seem a little expensive initially, but it offers other benefits like slowly releasing nutrients for the soil to absorb, thus fulfilling its feeding requirements.

When to water lemongrass?

Generally, it is recommended to water plants either early in the morning or early in the eveving (that is, post afternoon). The right time to water plants remains the same for each variety. Fortunately, lemongrass doesn’t follow a very different rule here and watering it in the early hours provides it with maximum benefits.

One of the simplest tips to help you stay right on track with the watering needs of your lemongrass plants is to never allow it to dry and become cranky. This will straight up lead to your plant dying. The soil should stay fertile, moist, and nutrient-rich at all hours of the day. A simple finger sticking test should be an easy way to identify when your lemongrass requires water.

Another tip to take into consideration while watering your lemongrass plants is to irrigate the plant deeply till the water reaches the soil. It helps improve the moisture retaining ability of your soil and keeps it moist and fertile for a long time.

Watering lemongrass in containers

While lemongrass is usually grown in the open garden, most people prefer to grow them in pots and containers of different shapes and sizes to add variety in their garden. When the plants are grown in containers, their watering requirements change dramatically.

One of the most important ingredients to ensure that the plants grow to their fullest potential in containers is a blend of organic compost with potting mix. Bedding your containers with the right mix of ingredients is important for keeping your plants healthy in the long run. This also prevents you with the trouble of repeatedly changing the potting mixture to suit the needs of the plant.

When your plants are grown while being confined to the boundaries of a container, it leaves little room for them to breathe. To allow the constant ventilation and aeration between the roots of the plant, drainage holes are mandatory. Create big holes in your container to prevent root rot and other issues that could arise from a boggy soil.

Additionally, most containers have wide side openings that facilitate the quick evaporation of water from the soil. Therefore, the watering requirements of lemongrass kept in containers increases as compared to those that are grown independently. So, if you water your regular plant once every two days, water your plant growing in a container once each day. You can adjust this frequency by sticking a finger and checking the texture.

Another way to deal with the evaporation occurring in containers is to add a layer of organic mulch over the potting mixture. Besides lowering the rate of evaporation, it also enhances the ability of the soil to retain moisture. Finally, you can go for a container with comparatively narrower side openings, but with large enough space to grow plants.

Lemongrass leaves turning brown

It is impossible to end our discussion about watering lemongrass without talking about one of the most common problems that it gives rise to, the leaves turning brown.

If your lemongrass plant is slowly turning brown without an unexplainable reason, it is probably because of the issues with proper watering and feeding.

When the plant doesn’t receive an adequate amount of water, it loses its ability to circulate nutrients and facilitate their absorption.

Therefore, if the leaves of your plant have started to turn yellow or brown, this is a sign to start watering them systematically. To speed up the recovery process, you can also feed your plant with a dose of nitrogen fertilizer at least once every month. It largely covers up for nutrient deficiency.

Key Takeaways

To summarize, watering lemongrass once every other day is recommended during every season. The plant loves to grow in moist soil and the roots tend to rot in soggy soil, so it is also important to do a quick finger check before watering your plants to avoid the issue of overwatering.

It is also desirable to create holes in the container in which you grow your plant to ensure proper aeration and drainage mechanism. Rest assured, your lemongrass plant will very smartly try to convey to you its deficiency needs, and if you have the right knowledge, you can allow proper growth conditions for it.
