Citronella plants are a popular choice for gardeners who want to keep mosquitoes away naturally. These plants are easy to care for and can be grown in pots or directly in the ground.
To ensure your citronella plant stays healthy and vibrant, it’s important to know how to care for it properly. This guide will help you care for your plant so it can live a long healthy life.
What are Citronella Plants
Citronella geraniums, also known as mosquito plants, are a type of geranium that has a scent similar to citronella. While they are not true citronella plants, they are often marketed as such because of their ability to repel mosquitoes and other insects.
Citronella geraniums have distinctive, serrated leaves that release their scent when crushed or rubbed. The scent is thought to be a natural insect repellent, although the effectiveness of the plant in repelling mosquitoes can vary depending on factors such as location and climate.
Citronella geraniums are often grown in containers or as bedding plants in gardens and are relatively easy to care for. They prefer well-drained soil and full sun to partial shade. In addition to their insect-repelling properties, citronella geraniums are also prized for their attractive foliage and colorful flowers.
Uses of the Citronella Plant
Citronella geraniums, also known as mosquito plants, are commonly used for their insect-repelling properties. Here are some of their uses:
Insect repellent: The scent of citronella geraniums is thought to be a natural insect repellent, particularly for mosquitoes. Some people crush the leaves and rub them on their skin to keep mosquitoes away, while others burn the leaves or use them in candles or diffusers.
Decorative plant: Citronella geraniums are attractive plants with distinctive leaves and colorful flowers. They are often used as bedding plants in gardens or grown in containers for their ornamental value.
Aromatherapy: The essential oil extracted from citronella geraniums is used in aromatherapy to promote relaxation and repel insects. The oil can be diffused in a room or added to massage oils or bath products.

Citronella geraniums are versatile plants that can be used for a variety of purposes, from repelling insects to adding flavor to food.
How much light do citronella plants need?
Citronella plants, both the true citronella plant (Cymbopogon nardus) and the citronella geranium (Pelargonium citrosum), require full sun to partial shade to grow properly. Ideally, they should receive at least 6 hours of direct sunlight per day. In areas with extremely hot summers, partial shade during the hottest part of the day may be beneficial.
If growing citronella plants indoors, they should be placed in a location with bright, indirect light, such as near a south-facing window. They may also benefit from supplemental grow lights to ensure they receive adequate light.
It’s important to note that citronella plants require a lot of light to thrive, and inadequate light can result in leggy growth, reduced flowering, and decreased effectiveness in repelling insects.
What kind of soil does citronella need?
Citronella plants prefer well-draining soil that is rich in organic matter. They do best in a soil pH of 4.5 to 5.5. A soil mix that is slightly acidic and has good drainage is ideal for these plants.
If you’re growing citronella plants in containers, you can use a high-quality potting mix that is specifically formulated for container gardening. Look for a mix that contains peat moss, perlite, vermiculite, or other ingredients that promote good drainage and aeration.
It’s also a good idea to amend the soil with organic matter, such as compost, to improve soil fertility and water retention. This will help keep the soil moist without becoming waterlogged, which can lead to root rot.
Citronella plants require well-draining soil that is rich in nutrients and organic matter. By providing the right soil conditions, you can help ensure that your plants thrive and continue to repel insects effectively.
How often should I water a citronella plant?
The watering requirements for citronella plants depend on several factors, such as the size of the plant, the temperature and humidity levels, and the type of soil it’s planted in. As a general guideline, citronella plants should be watered when the top inch of soil feels dry to the touch.
It’s important not to overwater citronella plants, as they are susceptible to root rot. To prevent this, allow the soil to dry out slightly between waterings and avoid watering the plant excessively.
In hot and dry conditions, citronella plants may need to be watered more frequently, while in cooler and more humid conditions, they may require less frequent watering. It’s important to monitor the plant and adjust your watering schedule accordingly.
Iif you’re growing citronella plants in containers, they may need to be watered more frequently than those planted in the ground. This is because container plants tend to dry out faster than those planted in the ground.
It’s important to strike a balance between keeping the soil moist and not overwatering the plant. By following these guidelines and monitoring the plant’s water needs, you can help ensure that your citronella plant stays healthy and thrives.
How to fertilize citronella
Citronella plants require regular fertilization to promote healthy growth and their insect-repelling properties. To fertilize citronella plants, you should use a balanced fertilizer that contains equal parts of nitrogen, phosphorus, and potassium. This can be in the form of slow-release or liquid fertilizer, applied every 4-6 weeks during the growing season (spring to fall), while following the instructions on the fertilizer package carefully.
Organic fertilizers such as compost, manure or fish emulsion can also be used. Avoid fertilizing during the winter months as citronella plants are dormant and do not require it. By following these tips, you can help ensure your citronella plant remains healthy and effective in repelling insects.
How To Prune Citronella Plants
Citronella plants are known for their aromatic oils that naturally repel insects. Pruning citronella plants is necessary to encourage new growth and maintain their bushy shape. Here are the steps to properly prune citronella plants:
Choose the right time: Pruning citronella plants is best done in the spring or early summer when they are actively growing.
Prepare your tools: Use a pair of clean and sharp pruning shears or scissors to avoid injuring the plant.
Identify the branches to prune: Look for branches that are dead, damaged, or diseased. Cut these off as close to the base as possible.
Decide on the shape: Decide on the shape you want for your citronella plant. Do you want it to be bushy or tall and thin? This will determine where you make your cuts.
Make the cut: Use the pruning shears to cut off the top of the plant, leaving a few inches of stem. This will encourage bushier growth. If you want your plant to be taller, cut off lower branches.
Remove excess growth: Citronella plants can become leggy if left to grow too tall. To prevent this, remove any side shoots that are growing from the base of the plant.
Clean up: Once you have finished pruning your citronella plant, clean up any debris around the base. Dispose of any diseased or dead branches.
Remember to keep your citronella plant well-watered and fertilized after pruning to encourage new growth. With proper care and pruning, your citronella plant will thrive and continue to repel insects for years to come.
How to Propagate Citronella Plants
Citronella plants can be propagated easily through stem cuttings or division. Here are the steps for both methods:
Propagation through Stem Cuttings:
Select a healthy citronella plant and choose a stem that is about 6 inches long and has several leaves.
Cut the stem with a sharp, clean knife just below a node, which is the point where leaves grow from the stem.
Remove the leaves from the lower 2/3 of the stem, leaving only a few at the top.
Dip the cut end of the stem in rooting hormone powder.
Plant the stem cutting in a pot filled with a well-draining potting mix and water thoroughly.
Cover the pot with a clear plastic bag to create a greenhouse effect and keep the cutting moist.
Place the pot in a warm, bright area, but out of direct sunlight.
Check the cutting regularly and mist it with water if it appears to be drying out.
After a few weeks, new growth should start to appear, which indicates that roots have formed. At this point, remove the plastic bag and care for the new plant as you would any other citronella plant.
Propagation through Division:
Dig up a mature citronella plant, preferably in the spring or fall.
Carefully separate the plant into two or more sections, ensuring that each section has a healthy root system.
Plant each section in its own pot or directly in the ground, making sure that the soil is well-draining and rich in organic matter.
Water thoroughly and keep the plant in a warm, bright area, but out of direct sunlight.
As the new plants grow, care for them as you would any other citronella plant, making sure to water regularly and fertilize every few weeks.
With either method, it’s important to remember that citronella plants prefer warm temperatures and plenty of sunlight. Also, be sure to keep the soil moist but not waterlogged. With proper care, your new citronella plants will thrive and provide you with fresh, fragrant foliage that is great for repelling insects.
Common Citronella Problems
Like any plant, citronella can encounter a number of problems that can impact its growth and health. Here are some common problems you may encounter with your citronella plant:
Pests: Citronella plants are naturally repellent to many pests, but they can still be attacked by insects like aphids, spider mites, and mealybugs. Inspect your plant regularly and use insecticidal soap or neem oil to treat any infestations.
Fungal diseases: Citronella plants can be susceptible to fungal diseases like powdery mildew and rust. These diseases can be caused by poor air circulation or overwatering. Avoid overhead watering and make sure your plant is getting adequate air flow. If necessary, treat with a fungicide.
Yellowing leaves: Yellowing leaves can be caused by overwatering or underwatering, nutrient deficiencies, or root rot. Check the soil moisture level and adjust watering accordingly. Make sure your plant is getting enough nutrients through regular fertilization.
Leggy growth: If your citronella plant is growing tall and leggy, it may not be getting enough sunlight. Move it to a brighter location, or consider pruning it back to encourage bushier growth.
Wilting: Wilting can be a sign of underwatering, overwatering, or a pest infestation. Check the soil moisture level and inspect the plant for pests. Adjust watering as needed.
By being vigilant and taking prompt action when problems arise, you can help your citronella plant stay healthy and thrive. Regular maintenance like pruning, fertilizing, and watering will also help keep your plant in tip-top shape.
Is the citronella plant a perennial or annual?
Citronella is a perennial plant, which means that it can live for more than two years if it is well cared for. In warm climates, citronella can grow year-round, but in colder climates, it may die back to the ground in the winter and regrow in the spring. Citronella is also often grown as an annual in colder climates, as it is sensitive to frost and does not tolerate cold temperatures well. In either case, citronella is a hardy plant that can be grown in pots or directly in the ground, making it a great addition to any garden or patio.
How to Overwinter Citronella Plant
If you live in a region with cold winters, you may need to take steps to overwinter your citronella plant so it can survive until the following growing season. Here are some tips for overwintering your citronella plant:
Bring the plant indoors: If you have a potted citronella plant, you can bring it indoors to overwinter. Place the plant in a sunny window or under grow lights, and water it sparingly, only when the soil is dry to the touch.
Prune the plant: Before bringing your citronella plant indoors, prune it back by about one-third to one-half of its height. This will help it conserve energy and focus on root growth.
Dig up the plant: If you have a citronella plant growing in the ground, you can dig it up and pot it to bring it indoors. Use a large pot with well-draining soil, and water the plant sparingly.
Keep the plant cool: Citronella plants prefer cool temperatures, so try to keep your overwintered plant in a room that is cool but not freezing. Avoid placing it near heaters or vents that can dry out the soil.
Monitor for pests: When bringing plants indoors, it’s important to keep an eye out for pests like spider mites and aphids, which can thrive in the warm, dry conditions of indoor environments. Check the plant regularly and treat any infestations promptly.
By following these tips, you can help your citronella plant survive the winter and thrive for many growing seasons to come.
Is citronella plant edible?
While citronella plants are sometimes used as flavoring or fragrance in some cuisines, they are not considered edible plants. In fact, the citronella plant contains citronella oil, which can be toxic if consumed in large quantities. It is not recommended to eat any part of the citronella plant, including the leaves, stems, or flowers.
It’s important to note that there are many other plants with similar-sounding names, such as lemon balm or lemon verbena, which are safe for consumption and can be used to add a citrusy flavor to food and drinks. If you’re looking for an edible plant with a similar flavor to citronella, it’s best to seek out one of these alternatives instead.
Do citronella plants actually repel mosquitoes?
Citronella plants are known for their mosquito-repelling properties. They contain citronella oil, which is a natural insecticide and has been used for centuries to repel mosquitoes and other insects.
The effectiveness of citronella plants in repelling mosquitoes can vary. Some studies have shown that citronella oil can be effective at repelling mosquitoes for short periods of time, but the effectiveness may wear off quickly or be inconsistent.
Citronella plants may be more effective when used in combination with other mosquito-repelling measures, such as mosquito nets, insecticides, or other natural repellents like lemon eucalyptus oil or lavender. It’s also important to note that while citronella plants may help to reduce mosquito populations in an area, they may not completely eliminate mosquitoes, especially in areas with high mosquito populations.
While citronella plants may help to repel mosquitoes to some extent, it’s important to use them in conjunction with other mosquito-repelling measures for best results.
By following these tips for caring for your citronella plant, you can help ensure it stays healthy and vibrant all season long. With regular watering, fertilizing, pruning, and pest control, your citronella plant can not only help keep mosquitoes away but also add a beautiful touch of greenery to your outdoor space.
