These varieties are bred to have increased resistance to common diseases, reducing the risk of infection or damage to your plants.

Cultivar Selection

Aside from cold-tolerance and disease resistance, there are also different cultivars of lemongrass that offer unique flavors and aromas. Some cultivars may have a stronger and more pronounced lemony scent, while others may have a sweeter and milder flavor. Consider your personal preferences and how you plan to use the lemongrass in your cooking when selecting the right cultivar for your garden.

Preparing the Soil

Proper soil preparation is essential for the successful growth of lemongrass. By ensuring the right pH, good drainage, and adding necessary amendments, you can create an optimal growing environment for your plants.

Soil pH and Drainage

Lemongrass prefers moderately acidic to neutral soil with a pH range of 6.0 to 7.5. Before planting, it’s important to test the pH of your soil and make any necessary adjustments. Additionally, lemongrass requires well-draining soil to prevent waterlogging, as excess moisture can lead to root rot. If your soil has poor drainage, you can improve it by adding organic matter such as compost or sand.

Amending the Soil

If your soil is lacking in nutrients, it’s beneficial to amend it before planting lemongrass. Incorporating organic matter, such as well-rotted manure or compost, can enrich the soil and provide essential nutrients for healthy growth. Consider conducting a soil test to identify any deficiencies and then add the appropriate amendments accordingly.


Mulching can help conserve moisture, suppress weed growth, and regulate soil temperature. Apply a layer of organic mulch around your lemongrass plants, such as straw or wood chips, to retain moisture and reduce the need for frequent watering. Additionally, mulch can also act as a natural weed barrier, minimizing competition for nutrients and reducing the need for manual weeding.

Providing the Optimal Growing Conditions

To ensure the optimal growth and development of lemongrass, it’s crucial to provide the right conditions in terms of sunlight, temperature, humidity, watering, and fertilizing.

Sunlight Requirements

Lemongrass thrives in full sunlight, requiring at least six to eight hours of direct sunlight per day. Choose a location in your garden that receives ample sunlight throughout the day, preferably away from any shade-casting structures or trees. Insufficient sunlight can result in stunted growth and a decrease in essential oils that contribute to the distinctive flavor and aroma of lemongrass.

Temperature and Humidity

Texas is known for its hot and humid climate, which is favorable for lemongrass growth. Lemongrass enjoys warm temperatures, typically ranging from 70°F to 95°F (21°C to 35°C). However, it’s important to note that extreme heat combined with dry conditions can stress the plants. Regular watering and providing some shade during the hottest parts of the day can help alleviate this stress.

Watering Needs

Lemongrass requires a consistent and adequate water supply to stay healthy and vibrant. Water your lemongrass plants regularly, aiming to keep the soil evenly moist but not waterlogged. In Texas, where temperatures can soar, it may be necessary to water more frequently, especially during periods of drought or intense heat. Monitor the moisture level of the soil and adjust your watering schedule accordingly.

Fertilizing Lemongrass

To support robust growth, it’s beneficial to fertilize your lemongrass plants. Apply a balanced, slow-release fertilizer or incorporate organic fertilizers, such as compost or well-rotted manure, into the soil during planting. Additional applications of fertilizer throughout the growing season can help replenish essential nutrients. Follow the manufacturer’s instructions for proper dosage and frequency of application.

Planting Lemongrass

Proper planting techniques are crucial for establishing healthy lemongrass plants. Consider the appropriate planting time, spacing, planting depth, and the option of transplanting seedlings.

Planting Time

In Texas, lemongrass can be planted during the spring or summer when the soil has warmed up and any danger of frost has passed. Aim for a soil temperature of around 50°F (10°C) or higher for successful germination and growth. Planting too early in the season can result in slower growth or even plant loss due to colder temperatures.


Lemongrass plants can grow up to 3-6 feet tall and spread out significantly. To allow for proper air circulation and prevent crowding, space your lemongrass plants accordingly. A spacing of 24-36 inches between plants is ideal, as this gives room for the plants to grow without becoming overcrowded.

Planting Depth

When planting lemongrass, ensure the root base is positioned just below the soil surface. Dig a hole deep enough for the root ball and gently cover it with soil, lightly tamping it down. Avoid planting too deep, as it can hinder root development and potentially suffocate the plant.

Transplanting Seedlings

If you choose to start lemongrass from seeds indoors, it’s possible to transplant the seedlings once they have developed a sufficient root system. Transplanting should occur after any danger of frost has passed and the seedlings have grown to a healthy size. Dig a hole the same depth as the root ball of the seedling, carefully transfer it from its container, and fill the hole with soil, gently pressing it around the plant.

Establishing and Caring for Lemongrass

To ensure the health and vitality of your lemongrass plants, it’s important to establish a care routine that includes regular watering, weed control, protection from frost, and periodic pruning.

Regular Watering

Proper hydration is crucial during the establishment phase and throughout the growing season. Continue to water your lemongrass plants regularly, checking the soil moisture level and adjusting the watering schedule as needed. Avoid overwatering, as it can lead to root rot, but also ensure the plants receive enough moisture to sustain healthy growth.

Weed Control

Maintaining weed-free beds around your lemongrass plants is essential to minimize competition for nutrients and water. Regularly inspect your garden for any weeds and remove them promptly either by hand or through the use of mulch. Mulching as mentioned earlier can help suppress weed growth and simplify weed control efforts.

Protecting from Frost

Although lemongrass is generally a hardy plant, it can be susceptible to damage from frost or freezing temperatures. In areas of Texas that experience occasional frost, consider using protective measures, such as covering your plants with blankets or utilizing frost cloth, during cold spells. This will help prevent damage to the foliage and enhance the chances of survival.


Periodic pruning is beneficial for maintaining the health and appearance of your lemongrass plants. Removing any dead or damaged leaves and stems can improve airflow and reduce the risk of disease. Additionally, pruning can also encourage bushier growth and the production of fresh and tender stalks. Use clean, sharp garden shears to make clean cuts, sanitizing them between cuts if necessary.

Harvesting and Storing Lemongrass

Knowing the right time to harvest, correct cutting techniques, as well as proper storage methods, can maximize the flavor and shelf life of your lemongrass harvest.

Harvesting Time

Lemongrass can typically be harvested when the stalks reach a height of around 12-18 inches or when the outer sheaths become pale yellow. Harvesting too early can result in immature stalks, while waiting too long can lead to tougher and less flavorful stalks. Observe your plants closely and harvest individual stalks as needed.

Cutting Lemongrass

To harvest lemongrass, select a stalk near the base, as close to the ground as possible. Use a sharp knife or pruners to make a clean cut just above the soil level. Avoid tearing or splitting the stalks, as this can introduce potential points of entry for pests or diseases. After harvesting, individual stalks can be used fresh or stored for later use.

Storing Fresh Lemongrass

If you’re not planning to use your freshly harvested lemongrass immediately, it can be stored in the refrigerator. Trim the stalks slightly and place them in a sealed plastic bag or container. Stored this way, lemongrass can stay fresh for up to two weeks. However, for longer-term storage, alternative methods such as drying or freezing are recommended.
