Maintaining Citronella Plants: Watering And Fertilizing
Proper maintenance of citronella plants includes regular watering and, if needed, fertilizing. It is essential to water the plants deeply when the top inch of soil is dry for potted plants and when the top two inches of soil are dry for plants in the ground. This allows the roots to access the moisture they need without creating a waterlogged environment that can harm the plant.
Fertilizing citronella plants should be done with caution. While they do not typically require frequent fertilization, a slow-release fertilizer can be applied during planting time to provide a steady supply of nutrients. Be sure to follow the fertilizer manufacturer’s instructions for the appropriate amount and timing of application. Over-fertilizing can lead to an overabundance of foliage at the expense of overall plant health.
- Bullet point 1: Regular watering is essential for healthy citronella plants.
- Bullet point 2: Water potted plants deeply when the top inch of soil is dry.
- Bullet point 3: Water plants in the ground deeply when the top two inches of soil are dry.
- Bullet point 4: Use caution when fertilizing citronella plants.
- Bullet point 5: Apply slow-release fertilizer during planting time for steady nutrient supply.
- Bullet point 6: Follow the fertilizer manufacturer’s instructions for the appropriate amount and timing of application.

Overwintering Citronella Plants Indoors
In regions where temperatures drop below the ideal range for citronella plants, it is necessary to bring them indoors for overwintering. When night temperatures consistently reach 45℉ or lower, it is time to move the plants indoors. Citronella plants can be kept indoors during the winter in a sunny window or with the assistance of grow lights.
To overwinter citronella plants successfully, ensure that they are placed in a location that receives at least six hours of direct sunlight per day. Water the plants whenever the soil is dry to the touch, but avoid overwatering. Indoor humidity can be lower than outside, so it is essential to monitor the soil moisture regularly.
In spring, when the chance of frost has passed and night temperatures consistently stay above 45℉, the citronella plants can be moved back outside. Acclimate them gradually to outdoor conditions by placing them in a shaded area first and gradually increasing their exposure to direct sunlight over the course of a few days.
Citronella plants are versatile and attractive additions to any garden. While their effectiveness in repelling mosquitos is still debated, they offer a refreshing fragrance and are relatively easy to grow. By providing adequate care and attention, citronella plants can thrive in various environments, adding beauty and aroma to your outdoor spaces.

Frequently Asked Questions
Does citronella plant come back every year?
The citronella plant is typically an evergreen perennial in zones 9 to 11 but behaves as an annual in areas with freezing temperatures. Its stems can become woody by the end of summer. To ensure the plant’s survival during winter, one can propagate a new one through layering in the late summer months. Therefore, while it may not come back every year in colder regions, it is possible to propagate and maintain the citronella plant for ongoing enjoyment.
Can a citronella plant survive winter?
While citronella plants thrive in warm weather and can survive year-round in hardiness zones 9 to 11, they cannot withstand the cold temperatures of winter in cooler climates. In order to protect the plants from being killed by winter temperatures, it is advisable to grow them in containers and bring them indoors during the winter. This way, you can ensure the survival of the citronella plants and maintain their growth for the following spring.
Can you regrow citronella plants?
Yes, citronella plants can be regrown through propagation. One method is to save pruned, non-woody stems or make cuttings of non-woody stems measuring three to five inches. After removing the bottom leaves, these stems or cuttings can be inserted into fresh potting soil. With proper care, these cuttings will develop into new citronella plants, allowing you to regrow and expand your citronella collection.
Does citronella plant spread?
Yes, the citronella plant does spread. The Citronella Mosquito Plant can expand up to 24 inches wide, allowing it to fill out a space in the landscape or container. To give the plant enough room to grow, it is recommended to space them 18-24 inches apart from each other. This spreading nature of the citronella plant allows for a fuller and more visually appealing arrangement in the garden or container.
