How to Plant Lemongrass: A Step-by-Step Guide

Lemongrass (Cymbopogon citratus) is a versatile and aromatic plant cherished for its culinary, medicinal, and insect-repellent properties. 

Cultivating lemongrass in Nigeria is straightforward, especially given the country’s favourable tropical climate. 

This guide will provide the necessary steps to plant, grow, and maintain a thriving lemongrass garden in Nigeria.

Description of the Lemongrass Plant

Lemongrass is a tall, perennial grass known for its strong citrus aroma and flavour.

The plant grows in dense clumps, reaching 3-6 feet tall.

Its leaves are long, slender, and slightly rough, arching gracefully to create a bushy appearance.

The Leaves are green in colour.

Planting Season for Lemongrass in Nigeria

The best time to plant lemongrass in Nigeria is during the rainy season, typically between April and October.

Starting the crop early in this season ensures that it receives adequate water for establishment without frequent irrigation.

Planting lemongrass during the rainy months allows the roots to develop a strong foundation, leading to healthier plants that can better withstand the dry season.

Lemongrass can also be planted during the dry season, but ensure adequate watering through irrigation for the plant.

Planting Lemongrass

Planting lemongrass involves several critical steps, from choosing an ideal location to maintaining proper soil conditions.

Here’s a breakdown of each stage:

Step 1: Choose a Location

Lemongrass thrives in areas with ample sunlight, so select a location that receives at least 6-8 hours of direct sunlight daily.

It prefers well-draining soil with a slightly loamy texture, as waterlogged soils can lead to root rot.

Raised beds or elevated plots are ideal for areas with heavy or clayey soils.

Also, make sure the chosen location is protected from strong winds, which can damage the tall, slender stalks of lemongrass.

Step 2: Land Clearing and Preparation

Clear the land of any weeds, stones, or debris that may hinder lemongrass growth.

Weed control is essential, as young lemongrass plants struggle to compete with aggressive weeds.

After clearing, loosen the soil to a depth of about 12 inches.

This depth allows the roots to penetrate easily and access essential nutrients.

If possible, work in some compost or well-rotted manure to enrich the soil with nutrients.

Step 3: Means of Propagation

Lemongrass can be propagated through seeds or by dividing established clumps (called tillers).

While growing from seed is possible, many Nigerian farmers and gardeners prefer to use division, as it provides faster growth and a quicker harvest.

Dividing lemongrass tillers is a straightforward method that involves separating the rooted sections from mature plants and replanting them.

This method also ensures that new plants inherit the parent plant’s qualities.

Step 4: How to Plant Lemongrass from Seed

If you choose to grow lemongrass from seed, follow these steps:

1. Sow the Seeds: Scatter the seeds lightly over the soil surface, covering them with a thin layer of soil or compost.
2. Keep Soil Moist: Maintain even moisture by misting with water, but avoid overwatering.
3. Transplant Seedlings: After 4-6 weeks, the seedlings should be large enough for transplanting. Gently remove them and plant them in your prepared garden bed, spacing them 2-3 feet apart.

How to Plant Lemongrass tillers (mature stalk divisions with roots)

1. Obtain Healthy Tillers: Find a mature lemongrass plant and gently separate a few stalks from the base, ensuring each has roots attached. If purchasing, select fresh stalks with intact roots.
2. Plant the Tillers: Dig small holes about 1-2 inches deep. Place each tiller in the hole, covering the root base and lower part of the stalk with soil. Space the tillers about 2-3 feet apart to allow for growth.
3. Water Thoroughly: After planting, water the tillers well to help them settle.

After a few weeks, the tillers will start producing new shoots, indicating successful growth.

Step 5: Watering

Lemongrass requires consistent moisture, especially during the early growth stages.

After planting, water the plants generously, making sure the soil remains moist but not soggy.

During the rainy season, you may only need to water when rainfall is scarce.

In the dry season, provide additional water to prevent the plants from drying out.

Regular, even watering will ensure healthy, tender shoots.

Step 6: Apply Manure

Lemongrass benefits greatly from organic matter, so apply well-rotted manure or compost around the base of the plants every 2-3 months.

Adding organic matter boosts soil fertility, improves water retention, and provides essential nutrients like nitrogen, which promotes leaf growth.

Avoid using fresh manure, as it can damage young roots.

If available, you can also apply organic fertilizers rich in potassium and phosphorus to support root development and overall plant health.

Maturity and Harvest

Lemongrass reaches maturity approximately 4-8 months after planting, depending on the variety and growing conditions.

When the plant stalks are around 1-2 feet in height, they are ready for harvest.

Harvesting involves cutting the stalks about 1 inch above the soil level.

Harvest mature stalks only, leaving younger shoots to develop further.

Regular harvesting promotes new growth, ensuring a steady supply throughout the year.

To harvest lemongrass leaves, cut them near the base and use them fresh or dried for culinary and medicinal purposes.

Pests and Diseases

While lemongrass is relatively resistant to many pests and diseases, a few issues can arise:

• Pests: Aphids, spider mites, and grasshoppers occasionally attack lemongrass, especially in dense plantings where airflow is limited.
• Diseases: Lemongrass can suffer from fungal diseases like rust and leaf blight, which thrive in humid, overcrowded conditions. Symptoms include discoloured spots, yellowing leaves, and overall stunted growth.

Pest and Disease Control

To control pests and diseases, consider these preventive and active measures:

1. Regular Inspection: Check your plants frequently for signs of pests or disease, especially during rainy and humid seasons.
2. Pruning and Thinning: Remove dead or overcrowded leaves to improve airflow around the plant. This helps reduce humidity, which can promote fungal growth.
3. Organic Solutions: Use neem oil or insecticidal soap to treat common pests like aphids and spider mites. These organic treatments are safe for the plant and the environment.
4. Crop Rotation and Companion Planting: Avoid planting lemongrass in the same location each year, as this can encourage pest and disease buildup. Consider planting lemongrass with other herbs, like basil or mint, which can naturally deter pests.

With regular care, including timely watering, feeding, and pest control, your lemongrass crop will thrive, providing you with a bountiful and aromatic harvest.

Growing lemongrass not only supports local culinary and medicinal needs but also adds a beautiful, fragrant presence to your garden or farm.
