Citronella Plant: Natural Mosquito Repellent You Can Grow!
Let’s dig into everything you need to know-from growing citronella in pots to using it effectively for bug control.
If you’ve ever swatted at mosquitoes on your porch and thought, “There must be a natural way to keep them away,” you’re in luck. The citronella plant is one of the most popular mosquito-repelling plants you can grow at home. It smells fresh and citrusy, looks beautiful in pots or garden beds, and adds a pleasant vibe to your outdoor (or even indoor) spaces.
But what exactly is a citronella plant? And does it really work against mosquitoes?
What is the Citronella Plant?
There are two types of plants commonly called “citronella”:
- Citronella Grass (Cymbopogon nardus or Cymbopogon winterianus): A true grass, this is the source of citronella oil used in natural insect repellents. It’s a tall, clumping plant with long, slender green blades.
- Citronella Scented Geranium (Pelargonium citrosum): Often sold as the “mosquito plant,” this is a geranium hybrid with lacy leaves and a lemony fragrance. It’s not the source of commercial citronella oil but is still known to repel bugs.
Pro Tip: If you’re after maximum mosquito-repelling power, go for citronella grass (Cymbopogon nardus).
How to Grow Citronella Plant Outdoors
1. Choose the Right Spot
Citronella loves warmth and sunlight. Place your plant in a sunny area—at least 6 hours of direct sunlight daily. It grows well on porches, decks, patios, or balconies.
2. Use Well-Draining Soil
Whether in the ground or a pot, make sure your citronella plant is in loose, well-draining soil. You can mix in compost to boost growth.
3. Water Regularly, But Don’t Overwater
Water when the top inch of soil feels dry. Avoid soggy roots—citronella plants don’t like “wet feet.”
4. Fertilize Every 3–4 Weeks
Use a balanced liquid fertilizer during the growing season (spring to early fall) to keep your plant lush and healthy.
Growing Citronella in Pots
Yes, citronella plants grow great in pots! This makes it easy to move them indoors when temperatures drop.
- Use a large container (at least 12 inches deep) for citronella grass.
- For scented geraniums, a medium pot (8–10 inches) works well.
- Make sure the pot has drainage holes to prevent root rot.
Does Citronella Really Repel Mosquitoes?
Yes—but not just by growing it. Crushing the leaves or using the essential oil from citronella grass releases the compounds (like citronellal and geraniol) that repel bugs.
Here’s how to use it:
- Rub crushed leaves directly on your skin (test first to avoid irritation).
- Make a DIY citronella spray using oil and water.
- Burn citronella candles made with true citronella oil for outdoor protection.
