A Comprehensive Guide on How to Grow Lemongrass

Lemongrass, with its refreshing citrus aroma and versatile culinary uses, is a popular herb in many cuisines around the world. Not only does it add a unique flavor to dishes, but it also offers numerous health benefits. If you’re a gardening enthusiast or simply someone who loves experimenting with flavors in the kitchen, learning how to grow lemongrass can be a rewarding experience. In this article, we will provide a step-by-step guide to help you successfully cultivate lemongrass in your own garden or indoor space.

Step-by-step Guide

Step 1: Choosing the Right Variety

Before starting your lemongrass journey, it’s essential to select the right variety. Two common types of lemongrass are Cymbopogon citratus and Cymbopogon flexuosus. C. citratus is often used in culinary applications and has a milder flavor, while C. flexuosus is favored for its strong lemony scent and is often used to make essential oils.

Step 2: Obtaining Lemongrass Stalks

Lemongrass can be propagated through stalks purchased from a nursery or by using stalks from fresh lemongrass purchased at a grocery store. If you choose to use store-bought lemongrass, make sure the stalks are fresh, plump, and have intact roots.

Step 3: Preparing the Stalks

Trim the upper portion of the stalk, leaving about 2 inches from the base. This portion is usually drier and tougher, so removing it will help stimulate new growth. Next, place the trimmed stalks in a glass of water, ensuring that the bottom 1 inch is submerged. Leave them in a warm spot with indirect sunlight, and within a couple of weeks, you should start noticing roots sprouting from the base of the stalks.

Step 4: Choosing the Right Location

Lemongrass thrives in warm and sunny conditions. Select a location in your garden or a spot indoors that receives at least six hours of direct sunlight daily. The soil should be well-draining to prevent waterlogging, as lemongrass does not tolerate excessive moisture.

Step 5: Planting Lemongrass

Once the stalks have developed a healthy root system, it’s time to plant them. Prepare the soil by incorporating organic matter, such as compost or well-rotted manure, to improve its fertility and drainage. Dig a hole that is slightly larger than the root ball of the lemongrass stalk, ensuring that the crown is level with the soil surface. Space each plant about 24 inches apart to allow sufficient room for growth.

Step 6: Watering and Maintenance

Water the newly planted lemongrass thoroughly, ensuring the soil is evenly moist but not saturated. Once established, lemongrass is relatively drought-tolerant and only requires watering during prolonged dry spells. Regularly check the soil moisture and adjust watering accordingly. Avoid overwatering, as it can lead to root rot.

Step 7: Fertilization

Lemongrass benefits from periodic feeding with a balanced organic fertilizer. Apply a slow-release granular fertilizer or liquid organic fertilizer during the growing season to provide essential nutrients. Follow the manufacturer’s instructions for dosage and frequency. Be cautious not to over-fertilize, as this can lead to weak growth.

Step 8: Harvesting Lemongrass

Lemongrass can be harvested once it reaches a height of about 12-18 inches. To harvest, cut the stalks at the base, close to the soil surface. Use a sharp knife or pruning shears to make a clean cut. It’s important to avoid damaging the neighboring stalks or the plant’s base. Harvesting stimulates new growth, so regular harvesting promotes a bushier plant.

Propagating Lemongrass

Propagating lemongrass is an excellent way to expand your herb garden or share this delightful plant with friends and family. There are a few different methods you can use to propagate lemongrass, including division, stalks, and seeds. Let’s explore each method in detail:

Division

Dividing an existing lemongrass plant is one of the easiest ways to propagate it. Here’s how to do it:

  • Carefully dig up the mature lemongrass plant, ensuring you don’t damage the roots.
  • Gently separate the clump of lemongrass into smaller sections, making sure each section has roots and several stalks.
  • Replant each divided section in well-draining soil, leaving adequate space between them.
  • Water the newly divided plants thoroughly and place them in a sunny location.

Stalks

Propagating lemongrass from stalks is a simple and popular method. Follow these steps:

  • Purchase fresh lemongrass stalks from a grocery store or farmers’ market.
  • Trim the upper portion of the stalk, leaving about 2 inches from the base.
  • Place the trimmed stalks in a glass of water, ensuring the bottom 1 inch is submerged.
  • Put the glass in a warm spot with indirect sunlight.
  • Change the water every few days to prevent stagnation and encourage root development.
  • Within a couple of weeks, you should observe roots sprouting from the base of the stalks.
  • Once the roots are well-established, transplant the lemongrass into pots or directly into the garden, following the planting instructions mentioned earlier.

Seeds

While lemongrass can be grown from seeds, it’s worth noting that the germination process can be a bit challenging. If you’re up for the challenge, here’s how you can propagate lemongrass from seeds:

  • Obtain fresh lemongrass seeds from a reputable source or collect seeds from mature lemongrass plants, if available.
  • Fill seed trays or pots with a well-draining potting mix.
  • Sprinkle the seeds evenly on the surface of the soil and lightly press them down.
  • Mist the soil with water to ensure it remains moist but not overly wet.
  • Place the trays or pots in a warm location with indirect sunlight.
  • Keep the soil consistently moist throughout the germination period, which can take several weeks.
  • Once the seedlings have developed a few leaves and are sturdy enough, transplant them into individual pots or the garden.
