Mosquitoes are highly sensitive to scents, and certain smells

Ah, summer evenings on the balcony are the perfect setting for relaxation, a cool drink in hand, and the soft hum of the city or the gentle rustling of leaves in the background. But there’s an unwelcome guest that can quickly ruin this idyllic scene: mosquitoes. These tiny, buzzing nuisances are more than just annoying; they can carry diseases and leave itchy bites. Fortunately, there’s a way to keep them at bay without resorting to chemical repellents or bug zappers. And no, it’s not mint. The answer is citronella.

In this article, we’ll dive into why citronella is the ultimate plant for your balcony to scare away mosquitoes. We’ll explore what makes this plant so effective, how to care for it, and other benefits it brings to your outdoor space. By the end, you’ll be convinced that citronella deserves a spot on your balcony this summer.

What is Citronella?

Citronella is a perennial grass native to tropical Asia. It’s commonly used in candles, oils, and other products designed to repel mosquitoes. The plant has a distinct lemony scent, which is derived from its essential oils—citronellal, citronellol, and geraniol. These oils are the key to citronella’s mosquito-repelling power.

Citronella grows in dense clumps, with long, slender leaves and tall stalks. It’s a hardy plant that thrives in warm climates, making it perfect for balconies in regions with hot summers. If you’ve been searching for a natural solution to keep mosquitoes away, citronella is your answer.

How Does Citronella Repel Mosquitoes?

Mosquitoes are highly sensitive to scents, and certain smells can either attract or repel them. Citronella’s strong lemony aroma is overwhelming to mosquitoes, disrupting their ability to detect the carbon dioxide and body heat emitted by humans and animals. This disorientation makes it difficult for mosquitoes to find a target, effectively keeping them away from your balcony.

Unlike chemical repellents that contain DEET or other harsh substances, citronella is a natural solution that doesn’t pose a risk to humans or pets. It’s also more pleasant to the senses, adding a refreshing fragrance to your outdoor space.

How to Grow Citronella on Your Balcony

Growing citronella on your balcony is relatively easy, even for those with limited gardening experience. Here are some tips to help you get started:

1. Choose the Right Variety

Citronella comes in two main varieties: Cymbopogon nardus and Cymbopogon winterianus. Both are effective at repelling mosquitoes, but Cymbopogon winterianus is often considered more potent. Choose the variety that suits your preference and availability in your area.

2. Select a Suitable Container

Citronella grows well in containers, making it ideal for balconies. Choose a large pot with good drainage, as citronella prefers well-draining soil. A pot with a diameter of at least 12 inches should suffice for a single plant.

3. Use Quality Potting Soil

Fill your container with high-quality potting soil that contains a mix of organic matter and drainage materials like perlite or vermiculite. Citronella doesn’t require particularly rich soil, but it should be well-draining to prevent root rot.

4. Provide Adequate Sunlight

Citronella thrives in full sun, so place your pot in a location that receives at least 6 to 8 hours of direct sunlight each day. If your balcony doesn’t get enough sun, consider using grow lights to supplement the natural light.

5. Water and Feed Regularly

Water your citronella regularly, but avoid overwatering. The soil should be consistently moist but not soggy. During the growing season, you can feed your citronella with a balanced liquid fertilizer every 4 to 6 weeks to promote healthy growth.

6. Prune and Maintain

Citronella grows quickly, so regular pruning is necessary to keep it manageable. Trim back any dead or yellowing leaves and remove flower stalks to encourage bushier growth. You can also harvest leaves to use in homemade mosquito repellents or potpourri.

Other Benefits of Citronella

While citronella is known for its mosquito-repelling properties, it offers other benefits that make it a valuable addition to your balcony garden:

1. Aromatic Ambiance

Citronella’s lemony scent adds a refreshing aroma to your outdoor space. The fragrance is pleasant to humans and can help create a relaxing atmosphere for your balcony gatherings.

2. Attractive Foliage

The tall, slender leaves of citronella add a touch of greenery to your balcony. The dense clumps create a lush look, providing a natural screen or backdrop for your outdoor decor.

3. Versatile Use

In addition to repelling mosquitoes, citronella can be used in various ways. You can crush the leaves to release their essential oils, which can then be rubbed on your skin to deter mosquitoes. The leaves can also be dried and used in potpourri or sachets to add fragrance to indoor spaces.

4. Environmental Benefits

By choosing citronella over chemical repellents, you’re making an environmentally friendly choice. Citronella is a renewable resource, and its cultivation doesn’t require harmful chemicals or pesticides.


If you’re looking for a natural way to keep mosquitoes off your balcony this summer, citronella is the plant to choose. Its mosquito-repelling properties, combined with its aromatic scent and attractive foliage, make it a versatile and valuable addition to any outdoor space.
