Introduction to Citronella Grass

Citronella grass (Cymbopogon nardus) is a fragrant and versatile plant, widely known for its strong lemon aroma. It is widely used in the perfume and fragrance industry for its delightful scent, which helps repel insects. Citronella grass is native to tropical regions and is a perennial plant that belongs to the Poaceae family. If you are interested in growing this aromatic grass, propagation is an essential step in increasing your plant stock. In this comprehensive guide, we will explore the various methods of propagating citronella grass to help you successfully grow your own supply.

1. Propagating citronella grass from seed

The first method of propagating citronella grass is from seed. To begin, collect mature seeds from a healthy citronella grass plant. Make sure the seeds are fully mature, as immature seeds may not germinate successfully. Fill a seed tray or small pots with well-draining potting soil and sprinkle the seeds evenly over the surface. Cover the seeds lightly with a thin layer of soil and mist the surface with water to provide moisture.

Place the seed tray or pots in a warm, bright location, preferably in indirect sunlight. Keep the soil moist at all times, but avoid overwatering as excessive moisture can cause rot. Germination usually occurs within two to four weeks. Once the seedlings have developed a few sets of true leaves, they can be transplanted to larger containers or directly into the garden.

2. Propagating Citronella Grass by Division

Another effective method of propagating citronella grass is by division. This method involves dividing a healthy clump of citronella grass into smaller sections, each containing roots and shoots. Begin by selecting a mature and well-established citronella grass plant. Carefully dig around the base of the plant, being careful not to damage the roots. Lift the entire clump off the ground and shake off excess soil.

Using a sharp, sterile knife or pruning shears, divide the clump into smaller sections. Each section should have an adequate number of healthy roots and shoots. Replant the divided sections immediately, making sure to place them at the same depth as they were growing previously. Water the newly transplanted sections thoroughly and provide adequate sunlight. With proper care, the divisions will establish and grow into new citronella grass plants.

3. Propagating Citronella Grass from Stem Cuttings

Stem cuttings are another reliable method of propagating citronella grass. Select a healthy and mature citronella grass plant and use clean, sharp pruning shears to cut a 3- to 4-inch section from the top of a non-flowering stem. Remove all leaves from the bottom two-thirds of the cut, leaving only a few leaves at the top.

Prepare a well-draining potting mix or a mixture of perlite and peat moss. Moisten the potting mix and make a small hole with a pencil or your finger. Dip the cut end of the stem into a rooting hormone powder to encourage root development. Insert the cutting into the prepared hole, making sure at least one knot is below the soil surface. Gently firm the soil around the cutting for stability.

Place the pot or tray in a warm, well-lit area out of direct sunlight. Mist the cutting regularly to maintain humidity and prevent excessive moisture loss. Within a few weeks, the cutting will develop roots and new growth. Once the roots are well established, the cutting can be potted into a larger container or transplanted to the garden.

4. Care and Maintenance of Propagated Citronella Grass

After successfully propagating Citronella grass, it is important to provide proper care and maintenance to ensure healthy growth. Citronella grass thrives in full sun and well-draining soil. Water the plants regularly, allowing the soil to dry out slightly between waterings. Avoid overwatering as this can cause root rot.

Fertilize every two to three months with a slow-release, well-balanced fertilizer. Prune the lawn regularly to maintain its shape and encourage bushier growth. It is also important to regularly check for pests and diseases, as citronella grass can be susceptible to certain insect and fungal problems. Treat any problems promptly with appropriate organic or chemical controls.


Propagation is a fantastic way to add to your Citronella grass collection and enjoy the many benefits of this fragrant plant. Whether you choose to propagate by seed, division, or stem cuttings, each method has its own advantages and can be successful with proper care. By following the guidelines outlined in this comprehensive guide, you can confidently propagate citronella grass and cultivate a thriving supply of this aromatic plant. Remember to provide the necessary care and maintenance to ensure its continued growth and enjoy the delightful scent it brings to your garden or perfume-making endeavors.


How do you propagate citronella grass?

Citronella grass can be propagated through various methods, including division, stem cuttings, and seeds.

1. How do you propagate citronella grass through division?

To propagate citronella grass through division, follow these steps:

Dig up an established clump of citronella grass.

Use a sharp knife or garden spade to divide the clump into smaller sections, ensuring that each section has a good amount of roots and foliage.

Plant the divided sections in well-draining soil, spacing them apart to allow room for growth.

Water the newly planted divisions thoroughly and keep the soil consistently moist until they establish roots and start to grow.

2. Can citronella grass be propagated through stem cuttings?

Yes, citronella grass can be propagated through stem cuttings. Here’s how:

Take a healthy, mature stem cutting from an established citronella grass plant. The cutting should be about 4-6 inches long.

Remove the lower leaves from the cutting, leaving only a few leaves at the top.

Dip the cut end of the stem in a rooting hormone powder to promote root development.

Plant the cutting in a pot filled with a well-draining potting mix or directly in the ground in a prepared bed.

Keep the soil moist and place the cutting in a warm, bright location, avoiding direct sunlight.

After a few weeks, the cutting should develop roots. Once the roots are established, you can transplant it to its permanent location.

3. Is it possible to propagate citronella grass from seeds?

Yes, citronella grass can be propagated from seeds. Here’s what you need to do:

Collect mature seeds from a citronella grass plant. The seeds are typically found in the flower heads.

Prepare a seed tray or small pots with a well-draining seed-starting mix.

Sow the seeds on the surface of the soil and lightly press them down. Do not cover the seeds with soil, as they require light to germinate.

Mist the soil with water to ensure it’s evenly moist.

Place the seed tray or pots in a warm location with indirect sunlight.

Keep the soil consistently moist but not waterlogged.

The seeds should germinate within 2-3 weeks. Once the seedlings are large enough to handle, you can transplant them to individual pots or a prepared garden bed.

4. When is the best time to propagate citronella grass?

The best time to propagate citronella grass is in the spring or early summer when the plant is actively growing. This allows the propagated sections or cuttings to establish roots and grow before the onset of winter or adverse weather conditions.

5. How long does it take for propagated citronella grass to establish and grow?

The time it takes for propagated citronella grass to establish and grow can vary depending on the propagation method used. Division and stem cuttings generally establish roots and start growing within a few weeks to a couple of months. Seeds may take longer, typically germinating within 2-3 weeks and requiring additional time to grow into mature plants. Patience and proper care are important during the establishment phase to ensure successful growth of propagated citronella grass.
