Understanding Your Green Guardians: Citronella and Lavender
Before we dig into planting, let’s get to know our stars. Both citronella and lavender are celebrated for their distinctive fragrances and their ability to keep unwelcome guests, particularly mosquitoes, at bay. However, they come from different botanical families and have unique needs.
Understanding these differences is key to successful cultivation.
Meet Citronella (Cymbopogon nardus)
Often confused with scented geraniums (which are sometimes marketed as “citronella geraniums”), true citronella is a perennial clumping grass, similar in appearance to lemongrass. It’s the source of the essential oil famous for its insect-repelling properties.
Its bright, lemony fragrance is delightful to humans but a deterrent to many flying insects. This tropical grass thrives in warm climates and can be a fantastic annual in cooler zones.
Meet Lavender (Lavandula angustifolia and relatives)
Lavender is a beloved shrub-like herb, famous for its soothing purple blooms and unmistakable aroma. While we love its scent, many insects, including mosquitoes, moths, and even deer, tend to steer clear.
There are several popular varieties, including English lavender (Lavandula angustifolia), French lavender (Lavandula dentata), and Spanish lavender (Lavandula stoechas), each with slightly different appearances and hardiness levels.
Choosing the Right Spot: Sun, Soil, and Shelter
The success of your citronella and lavender plant pairing largely depends on providing them with their ideal growing conditions. While they both love sun, their soil and watering preferences have some nuances.
Sunlight Requirements
Both citronella and lavender are sun-worshippers! They absolutely thrive in areas that receive at least 6-8 hours of direct sunlight per day. More sun generally means more vigorous growth and a stronger fragrance.
If you’re in a region with scorching summer afternoons, a little afternoon shade might be beneficial for lavender, but citronella will happily soak up the rays.
Soil Preferences
This is where their needs diverge slightly, and it’s crucial for healthy growth.
- Citronella: Prefers rich, well-draining soil. It’s not overly picky about pH but appreciates consistent moisture without being waterlogged. A good quality potting mix or amended garden soil with compost works wonders.
- Lavender: Demands excellent drainage above all else. It hates “wet feet” and is prone to root rot in heavy, soggy soils. Aim for sandy, gravelly, or loamy soil with a neutral to slightly alkaline pH (6.5-7.5). If your soil is heavy clay, amend it generously with sand, grit, or perlite to improve drainage.
For the best results when growing a citronella and lavender plant together, consider planting them in separate containers or creating a raised bed with different soil compositions, if your garden soil isn’t ideal for both.
Protection from the Elements
Citronella grass is sensitive to frost. In zones below USDA Zone 9-10, it’s best grown as an annual or brought indoors for winter. Lavender, especially English varieties, is quite hardy (USDA Zones 5-9) and can withstand colder temperatures, but appreciates some shelter from harsh winter winds.
Consider planting them near a south-facing wall or in a sheltered spot if you’re pushing their hardiness limits.
Planting Your Pest-Repelling Powerhouses
Ready to get your hands dirty? Planting these beauties is straightforward, whether you’re starting from nursery plants or seeds.
Starting from Nursery Plants
This is often the easiest and quickest way to establish your plants.
- Choose Healthy Plants: Look for plants with vibrant green foliage, no signs of yellowing or pests, and a strong, bushy appearance.
- Prepare the Hole: Dig a hole twice as wide as the root ball and just as deep. For lavender, ensure the soil is particularly well-draining.
- Planting: Gently remove the plant from its container. Loosen any circling roots. Place the plant in the hole so the top of the root ball is level with the surrounding soil.
- Backfill and Water: Backfill with your prepared soil, gently firming around the base. Water thoroughly to settle the soil and eliminate air pockets.
When planting multiple lavender plants, space them about 18-24 inches apart to ensure good air circulation, which helps prevent fungal issues.
Growing from Seed (A Patience Game)
While possible, growing citronella and lavender from seed requires more patience and specific conditions.
- Citronella: Seeds can be started indoors 6-8 weeks before the last frost. They need warm temperatures (around 70-75°F or 21-24°C) to germinate.
- Lavender: Lavender seeds require a period of cold stratification (mimicking winter conditions) to germinate successfully. This often means placing them in a damp paper towel in the refrigerator for 3-6 weeks before planting.
Don’t worry—these flowers are perfect for beginners! Most gardeners opt for purchasing established plants for a quicker start and more reliable results, especially when combining the citronella and lavender plant pairing.
Care and Maintenance: Keeping Them Thriving
Once planted, consistent care will ensure your citronella and lavender flourish and continue to deter pests.
Watering Wisdom
- Citronella: Likes consistent moisture. Water regularly, especially during dry spells, but allow the top inch or two of soil to dry out between waterings. Avoid letting it sit in soggy conditions.
- Lavender: Is drought-tolerant once established. Overwatering is the quickest way to kill it! Water deeply but infrequently. Allow the soil to dry out completely between waterings. In humid climates, even less water is needed.
A good rule of thumb is to check the soil moisture with your finger before watering. If it feels damp, wait.
Fertilization
Neither plant is a heavy feeder.
- Citronella: A balanced, slow-release granular fertilizer once or twice during the growing season can encourage lush growth.
- Lavender: Generally doesn’t need much fertilizer, especially in good soil. Too much nitrogen can lead to leggy growth and fewer flowers. If your soil is poor, a light application of compost in spring is usually sufficient.
Pruning for Health and Vigor
Pruning is essential for both plants to maintain their shape, encourage new growth, and maximize their repellent properties.
- Citronella: Trim back any leggy or yellowing leaves to encourage bushier growth. You can also harvest outer stalks as needed for their fragrance.
- Lavender: Prune annually in early spring after the last frost, or lightly after the first flush of blooms. Cut back about one-third of the plant’s growth, shaping it into a compact mound. Avoid cutting into the old, woody stems too much, as they may not regrow. Regular deadheading of spent flowers will also encourage more blooms.
Proper pruning ensures your lavender remains vibrant and doesn’t become leggy or woody too quickly.
Pest and Disease Management
The good news is that both citronella and lavender are relatively pest-free, largely due to their own repellent properties!
- Citronella: Can occasionally attract spider mites or aphids if stressed, but these are rare. A strong spray of water or insecticidal soap can manage them.
- Lavender: Its strong scent deters most common garden pests. The biggest threat is root rot from overwatering. Ensure good drainage and proper watering habits.
Always inspect your plants regularly for any signs of trouble. Early detection makes treatment much easier.
Companion Planting: Maximizing the Power of Citronella and Lavender
While these two are a fantastic pair, consider other companion plants to create an even more effective and beautiful garden ecosystem.
- Marigolds: Known to repel nematodes and various insects.
- Rosemary: Another fragrant herb that deters mosquitoes and other pests.
- Basil: A great culinary herb that also helps keep flies and mosquitoes away.
- Mint: Be careful, as mint can be aggressive, but its strong scent is a known insect deterrent. Consider planting it in containers to control its spread.
Strategically placing these plants around your seating areas or garden paths will enhance your pest-free zones.
Real-World Uses and Benefits
Beyond their beauty and pest-repelling prowess, the citronella and lavender plant offers numerous practical applications.
- Outdoor Living Spaces: Plant them around patios, decks, and seating areas to create natural insect barriers. Place potted citronella near entryways.
- Walkways and Borders: Use lavender as a fragrant border along paths where its scent can be enjoyed when brushed.
- Container Gardening: Both plants do exceptionally well in pots, which allows you to move them closer to where you need pest protection most. This is especially useful for citronella in colder climates.

Harvesting for Repellents:
- Citronella: You can crush the leaves and rub them on your skin (perform a patch test first!) for a temporary mosquito deterrent.
- Lavender: Dried lavender flowers can be used in sachets to repel moths in closets or simply for their calming fragrance.
- Attracting Pollinators: While repelling pests, lavender is a magnet for beneficial pollinators like bees and butterflies, contributing to a healthy garden ecosystem.
Always be mindful of skin sensitivities when using plant material directly on the skin. If you have sensitive skin, it’s best to avoid direct contact with crushed citronella leaves and opt for commercial products containing its essential oil.
Troubleshooting Common Issues
Even experienced gardeners face challenges. Here are a few common problems and how to tackle them:
- Lavender Turning Brown/Yellow: This is almost always a sign of overwatering or poor drainage. Reduce watering frequency, and ensure the soil drains well. If in a pot, check for clogged drainage holes.
- Leggy Citronella: Not enough sunlight or nutrients. Move to a sunnier spot, or consider a light application of balanced fertilizer. Regular trimming can also promote bushier growth.
- Lack of Fragrance: Often due to insufficient sunlight. Both plants need ample sun to develop their strong aromatic oils. Ensure they’re getting at least 6-8 hours daily.
- Lavender Not Flowering: Could be too much nitrogen fertilizer (which promotes leafy growth over flowers), not enough sun, or improper pruning (cutting too much into old wood).
Don’t worry if you encounter a hiccup! Gardening is a continuous learning process. Observe your plants closely, and they’ll often tell you what they need.
Frequently Asked Questions About Citronella and Lavender Plant
Can I plant citronella and lavender together in the same pot?
You can, but it’s not ideal long-term due to their differing watering needs. Citronella prefers consistent moisture, while lavender thrives in drier conditions. If you do, ensure the pot is very large, and you monitor moisture levels carefully, perhaps creating a slight mound for lavender’s root ball.
Is the citronella plant safe for pets?
While the essential oil is often used in pet products, direct ingestion of the plant material in large quantities can cause mild stomach upset in pets. It’s generally considered low toxicity, but it’s always wise to monitor pets and prevent them from munching on plants.
How do I make my lavender plant bloom more?
Ensure it gets full sun (at least 6-8 hours), has excellent drainage, and avoid over-fertilizing with nitrogen. Regular deadheading of spent flowers and proper annual pruning in spring will also encourage abundant blooms.
Can I grow citronella indoors during winter?
Yes! In colder climates, bring your potted citronella indoors before the first frost. Place it in a sunny window and reduce watering. It may not grow as vigorously but can overwinter successfully until spring.
What’s the best type of lavender for mosquito repellent?
All lavender varieties possess mosquito-repelling properties due to their natural compounds. English lavender (Lavandula angustifolia) is often favored for its strong fragrance and hardiness, making it a popular choice for gardens.
