Introduction to Citronella Plants
Citronella plants, known botanically as
- Cymbopogon nardus* and
- Cymbopogon winterianus*, are perennial grasses native to Southeast Asia. They are renowned for their distinctive, lemony-citrus scent, which emanates from their aromatic leaves.

Growing Citronella Plants
Citronella plants, known for their fragrant leaves and mosquito-repelling properties, are relatively easy to grow. With the right conditions and care, you can cultivate these powerful herbs in your garden or containers.
Soil Requirements
Citronella plants thrive in well-drained soil that is slightly acidic to neutral. The ideal pH range is between 6.0 and 7.0. They prefer a soil mixture that is rich in organic matter, which helps retain moisture and provides essential nutrients.
Sunlight and Temperature
Citronella plants need at least six hours of direct sunlight daily for optimal growth. They are heat-tolerant and can withstand temperatures up to 90 degrees Fahrenheit. However, prolonged exposure to extreme heat can stress the plants. In colder climates, it’s best to grow citronella in containers that can be moved indoors during the winter months.
Watering and Fertilization
Citronella plants require regular watering, especially during hot and dry weather. The soil should be kept consistently moist but not waterlogged. It’s essential to allow the top inch of soil to dry out between waterings. You can fertilize citronella plants every few weeks during the growing season with a balanced liquid fertilizer.
Propagation Methods
Citronella plants can be propagated through various methods, including seeds, cuttings, and division.
- Seeds: Starting citronella plants from seeds can be a bit challenging, as they have a low germination rate. Sow seeds indoors in a seed tray filled with a seed-starting mix. Keep the soil moist and warm, and provide bright, indirect light.
Seedlings typically emerge within 2-4 weeks.
- Cuttings: This is the most common and successful method of propagating citronella plants. Take 4-6 inch stem cuttings from healthy plants, ensuring that each cutting has at least two nodes. Remove the lower leaves and dip the cut end in rooting hormone.
Citronella plants are known for their potent mosquito-repelling properties, making them a natural and effective way to enjoy your outdoor space without the pesky bites.

Citronella plants are also quite easy to grow, preferring full sun and well-drained soil. With proper care, they’ll reward you with beautiful foliage and a natural way to keep insects at bay.
Plant the cuttings in a pot filled with a rooting mix and keep the soil moist. Rooting typically takes 4-6 weeks.
- Division: This method is best for established plants. Gently dig up the plant and separate the root ball into smaller divisions, each with a healthy root system and leaves. Plant the divisions in separate pots or in the garden, ensuring they have adequate space to grow.
Protecting Citronella Plants from Pests and Diseases
Citronella plants are generally resistant to pests and diseases. However, they can be susceptible to certain problems, including:
- Aphids: These small insects can suck sap from the leaves, causing them to curl and yellow. You can control aphids by spraying the plants with insecticidal soap or neem oil.
- Root Rot: Overwatering can lead to root rot, a fungal disease that can damage the roots and kill the plant. Ensure proper drainage and avoid overwatering.
- Leaf Spot: This fungal disease causes brown spots on the leaves. To prevent leaf spot, avoid overhead watering and ensure good air circulation around the plants.
Harvesting and Using Citronella Plants
Harvesting citronella leaves at the right time is crucial for maximizing the essential oil content, which is responsible for the plant’s distinct aroma and insect-repelling properties.
Harvesting Citronella Leaves, Citronella Plant Benefits and Uses: How to Grow and Use This Powerful Herb
The optimal time to harvest citronella leaves is when the plant is in full bloom, typically during the summer months. This is when the essential oil concentration is at its peak. You can identify the ideal time by observing the plant’s flowers.
Once the flowers have fully opened, it’s the perfect time to harvest the leaves.
Extracting Citronella Oil
Citronella oil can be extracted from the leaves using a simple distillation method. This process involves heating the leaves with water, allowing the essential oil to vaporize and condense into a separate container. Here’s a step-by-step guide:
- Gather fresh citronella leaves and wash them thoroughly.
- Place the leaves in a large pot with a lid. Add enough water to cover the leaves.
- Attach a copper coil or a glass condenser to the lid, ensuring the other end of the coil is submerged in a separate container filled with ice water.
- Heat the pot on a stovetop, bringing the water to a boil. As the water boils, the essential oil in the leaves will vaporize and rise.
- The vapors will travel through the coil, where they will condense back into a liquid form and drip into the ice-cold container.
- Continue heating the pot for several hours until the oil extraction process is complete. The resulting liquid in the container will be citronella oil.
Using Citronella Oil
Citronella oil can be used in various ways, both directly and indirectly, to harness its insect-repelling and aromatherapy benefits.
Direct Application
Citronella oil can be applied topically as a natural insect repellent, but it’s important to dilute it first. Mixing a few drops of citronella oil with a carrier oil, such as coconut oil or jojoba oil, can create a safe and effective insect repellent.
Apply the diluted oil to exposed skin, avoiding sensitive areas like the eyes and mouth.
Aromatherapy
Citronella oil can be used in diffusers or candles for relaxation and pest control. The scent of citronella is known to have calming effects and can help create a peaceful atmosphere.
For effective pest control, consider using a diffuser with citronella oil in areas prone to insect infestations.
Cleaning Solutions

Citronella oil can trigger allergic reactions in some individuals. Symptoms may include skin irritation, redness, itching, and in severe cases, even anaphylaxis. It is recommended to perform a patch test on a small area of skin before applying citronella oil topically.
If any irritation occurs, discontinue use immediately and consult a medical professional.
Citronella Oil During Pregnancy and Breastfeeding
The safety of using citronella oil during pregnancy and breastfeeding is not fully established. There is limited research on the potential effects of citronella oil on pregnant women and their developing babies, as well as on breastfeeding mothers and infants.
It’s advisable to exercise caution and consult with a healthcare provider before using citronella oil during these periods.
Storage and Shelf Life
Citronella oil should be stored in a cool, dark place, away from direct sunlight and heat. Proper storage helps to maintain its potency and prevent degradation. Store it in a tightly sealed container to prevent evaporation and contamination. The shelf life of citronella oil can vary depending on storage conditions and the quality of the oil.
However, generally, it can last for several years if stored properly.
