Lemongrass Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 22, 2023

Lemongrass, with its refreshing citrus aroma and versatile culinary uses, is a popular herb among gardeners and cooking enthusiasts. Growing your own lemongrass plant can be a rewarding experience, and it all starts with the seeds. In this guide, we will explore the process of storing, sowing, and germinating lemongrass plant seeds to help you successfully cultivate this delightful herb in your garden.

Storing Lemongrass Plant Seeds

Storing lemongrass plant seeds properly is essential to ensure their viability when it’s time to sow them. Here are some steps you can take to store your lemongrass seeds correctly:

  1. Harvesting: To obtain lemongrass seeds, allow a mature lemongrass stalk to flower. The flowers will produce small green seed pods. Harvest the seed pods when they turn brown and start to dry out.

  2. Drying: After harvesting the seed pods, spread them out on a clean surface or a piece of paper towel. Allow them to dry completely in a well-ventilated area for about two weeks. Make sure to keep them away from direct sunlight and moisture.

  3. Storage container: Once the seed pods are fully dried, transfer them to an airtight container such as a glass jar or a zipper-lock bag. Ensure that the container is clean and dry before placing the seeds inside.

  4. Labeling: It’s crucial to label your storage container with the date of harvest and the variety of lemongrass from which the seeds were collected. This way, you can keep track of the freshness and origin of your seeds.

  5. Storage conditions: Store your labeled container in a cool, dry place away from direct sunlight. A temperature range of 40-50°F (4-10°C) is ideal for maintaining seed viability. Avoid exposing the seeds to extreme temperatures, as it can reduce their germination rate.

By following these steps, you can preserve the viability of your lemongrass plant seeds for several years.

Sowing Lemongrass Plant Seeds

Sowing lemongrass plant seeds is a relatively simple process. Here’s how you can sow your stored seeds to kickstart the germination process:

  1. Preparing the soil: Lemongrass thrives in well-draining soil with a slightly acidic pH level of 6.0-7.5. Prepare your garden bed or container by mixing compost or organic matter into the soil to improve its fertility and drainage.

  2. Sowing depth: Scatter the lemongrass seeds evenly over the prepared soil surface. Lightly press the seeds into the soil, ensuring they are covered with a maximum depth of ¼ inch (0.6 cm). Avoid burying the seeds too deep, as they require light for germination.

  3. Watering: After sowing the seeds, water the soil gently to keep it evenly moist but not waterlogged. Using a misting spray bottle or a gentle shower setting on your watering can will help prevent displacing the seeds.

  4. Germination conditions: Place a clear plastic cover or a transparent plastic bag over the seeded area to create a mini-greenhouse effect. This will help retain moisture and warmth, promoting faster seed germination. Keep the area at a consistent temperature of around 70-85°F (21-29°C).

  5. Germination time: Lemongrass seeds usually take anywhere from 14 to 21 days to germinate. During this period, monitor the moisture levels regularly and remove the plastic cover once sprouts start to emerge.

Germinating Lemongrass Plant Seeds

Germinating lemongrass plant seeds successfully requires consistent care and attention. Here are some essential tips to ensure optimal germination:

  1. Watering: Maintain even moisture in the soil by regularly watering the newly germinated seedlings. Avoid overwatering, as it can lead to root rot. Allow the soil to dry slightly between waterings to prevent fungal diseases.

  2. Lighting: Lemongrass plants prefer full sun, so provide them with at least 6-8 hours of direct sunlight each day. If you’re growing lemongrass indoors, place it near a south-facing window or use grow lights to provide sufficient light intensity.

  3. Transplanting: Once the seedlings have developed a few sets of true leaves and are sturdy enough to handle, you can transplant them into individual pots or directly into the garden bed. Ensure proper spacing, allowing at least 24 inches (61 cm) between each plant.

  4. Fertilizing: Apply a slow-release balanced fertilizer or organic compost around the base of the lemongrass plants every two to three months to provide them with essential nutrients for vigorous growth.

  5. Harvesting: Depending on the lemongrass variety, you can start harvesting the leaves and stalks when they reach a suitable size, usually around 3-4 months after planting. Cut off the outer leaves close to the base to promote continuous growth.

By following these guidelines, you can enjoy a bountiful harvest of fresh lemongrass throughout the growing season.

In conclusion, growing lemongrass from seeds can be a rewarding and fulfilling experience. By properly storing, sowing, and germinating lemongrass plant seeds, you can successfully cultivate this delightful herb in your own garden or even indoors. So go ahead, get your hands on some lemongrass seeds and embark on your journey towards enjoying the aromatic and zesty flavors that this versatile herb has to offer.
