How to Grow Lemongrass From Seeds

Lemongrass is a versatile and aromatic herb widely used in cooking, traditional medicine, and even ornamental gardening. Known for its citrusy fragrance and flavor, it is a favorite in many cuisines, particularly Southeast Asian dishes. Growing lemongrass from seeds can be a rewarding process, allowing you to cultivate a fresh and sustainable supply right in your garden or home.

This guide on how to grow lemongrass from seeds will walk you through the steps to successfully grow lemongrass from seeds, ensuring a thriving and healthy plant.

Choosing and Sourcing Lemongrass Seeds

Selecting the right lemongrass seeds is essential to ensure successful growth and a healthy plant. When choosing seeds, opt for high-quality, organic, and non-GMO varieties from reputable suppliers or garden centers. Look for seeds that are specifically labeled as “Cymbopogon” species, as this indicates authentic lemongrass.

Online marketplaces can also provide a wide range of options, but it’s crucial to read reviews and verify the credibility of the seller before purchasing. If possible, purchase seeds that are fresh, as older seeds may have reduced germination rates. Investing in good-quality seeds at the start will set the foundation for a flourishing lemongrass harvest.

When to Plant Lemongrass Seeds?

The best time to plant lemongrass seeds largely depends on your local climate. Lemongrass thrives in warm temperatures, so it’s ideal to start planting after the last frost date in your area. For gardeners in cooler climates, you can start seeds indoors approximately 6-8 weeks before the last expected frost.

Use peat pots or seed trays to germinate the seeds in a warm, sunny location or under grow lights. Once temperatures consistently stay above 50°F (10°C), seedlings can be transplanted outdoors. Planting at the right time ensures optimal growth and a healthy harvest.

10 Step-by-Step Guides on How to Grow Lemongrass From Seeds

Step 1: Choose the Right Variety

Selecting the appropriate variety of lemongrass is essential for successful cultivation. There are two main types of lemongrass—East Indian (Cymbopogon flexuosus) and West Indian (Cymbopogon citratus). While both are suitable for culinary and medicinal uses, West Indian lemongrass is more commonly grown in home gardens due to its milder flavor and ease of cultivation.

Research which variety is best suited to your needs and your local climate conditions before purchasing seeds.

Step 2: Soak the Seeds

To improve germination rates, it is recommended to soak lemongrass seeds before planting. Place the seeds in a bowl of lukewarm water and let them soak for 12 to 24 hours. This process helps soften the seed coat, allowing water to penetrate more easily and stimulating the germination process.

Once soaked, gently pat the seeds dry with a paper towel before moving on to the next step in planting.

Step 3: Prepare the Soil 

Lemongrass thrives in well-draining, nutrient-rich soil with a slightly acidic to neutral pH range (6.0 to 7.5). Begin by selecting a sunny spot in your garden or preparing a large container with appropriate drainage holes.

Loosen the soil to a depth of at least 12 inches to promote healthy root growth, and mix in compost or organic matter to enhance fertility and moisture retention. If planting in a container, opt for a quality potting mix that supports proper drainage. Properly preparing the soil sets the foundation for robust lemongrass growth and ensures the plants have the resources they need to flourish.

Step 4: Plant the Seeds

Once the soil is prepared, it’s time to plant your lemongrass seeds. Sow the seeds evenly over the surface of the soil, ensuring they are spaced about an inch apart. Lightly press the seeds into the soil, but avoid burying them too deeply, as they require some light for germination.

Gently mist the area with water to keep the soil moist, but not overly saturated. For containers, follow the same process, ensuring the seeds have adequate space to grow. Place your container or garden plot in a warm, sunny location to maximize germination. Within a week or two, you should start to see tiny sprouts emerging, signaling the beginning of your lemongrass plants.

Step 5: Water Regularly

Lemongrass thrives in consistently moist soil, so it’s important to water your plants regularly. Check the soil often to ensure it doesn’t dry out, especially during hot or windy weather. Aim to keep the soil damp but avoid overwatering, as soggy conditions can lead to root rot.

If you’re growing lemongrass in containers, ensure proper drainage to prevent waterlogging. Regular watering will support healthy growth and help your lemongrass flourish.

Step 6: Provide Adequate Sunlight 

Lemongrass thrives in full sun, requiring at least 6 to 8 hours of direct sunlight daily to grow optimally. Choose a location in your garden or home that receives plenty of natural light throughout the day. If you’re growing lemongrass indoors, placing it near a south-facing window can help ensure it gets enough sunlight.

For container-grown lemongrass, you can move the pots to follow the sun’s path to maximize exposure. Adequate sunlight will promote vigorous growth and keep the plants robust and healthy.

Step 7: Fertilize Sparingly

Lemongrass thrives in nutrient-rich soil, but it does not require heavy fertilization. Apply a balanced, slow-release fertilizer once every few months to provide essential nutrients without overwhelming the plant. Alternatively, you can use an organic compost or liquid fertilizer diluted to half strength every few weeks during the growing season.

Be careful not to over-fertilize, as this can lead to excessive leaf growth with a weaker flavor. Always follow the instructions on your chosen fertilizer to avoid any potential nutrient imbalances.

Step 8: Harvesting

Harvesting should be done when the plant has reached maturity, typically indicated by vibrant, healthy leaves or fully developed fruits, depending on the type of plant. Use clean, sharp scissors or pruning shears to cut only what you need, taking care not to damage the main stems.

For herbs, pick the leaves regularly to encourage new growth, while fruits and vegetables should be harvested at their peak ripeness for optimal flavor and nutrition. Harvesting in the morning is often recommended, as plants are more hydrated and flavorful during this time. Proper harvesting techniques ensure the plant continues to thrive and produce throughout its growing season.

Step 9: Storing

To store lemongrass, you can freeze it or dry it for later use. To freeze, chop the stalks into small pieces and place them in an airtight container or freezer bag. To dry, cut the stalks into thin pieces and lay them out on a baking sheet in a single layer.

Leave them to dry in a warm, well-ventilated area until they are brittle. Store dried lemongrass in an airtight container.

Step 10: Cooking with Lemongrass

Lemongrass is a versatile herb that can be used in many different types of dishes. It is commonly used in Asian cuisine, but it can also add a unique flavor to soups, stews, and marinades.

To use lemongrass in cooking, start by removing the tough outer layers of the stalks and slicing the softer inner core into thin rounds. You can then add it to your dish whole or bruise it with a knife or mortar and pestle to release more flavor.

Following these steps on how to grow lemongrass from seeds, you can also easily grow your own lemongrass at home. This will not only provide you with a fresh supply of the herb, but it can also save you money in the long run.

Caring for Seedlings

Once your lemongrass seeds have germinated and sprouted into seedlings, proper care is essential to ensure healthy growth. Begin by keeping the soil consistently moist but not waterlogged, as lemongrass thrives in well-drained conditions. Place the seedlings in a location where they receive plenty of sunlight, ideally 6 to 8 hours per day. Protect the young plants from strong winds and extreme temperatures, as they are still delicate at this stage.

If you notice the seedlings becoming crowded, thin them out or transplant them into larger pots or garden beds, allowing adequate space for each plant to grow. Regularly check for pests or diseases and remove any weeds that may compete for nutrients in the soil. Providing these nurturing conditions will help your seedlings grow into robust and flavorful lemongrass plants.
