You can plant lavender with citronella, and doing so is a fantastic way to build a fragrant, functional, and pest-deterring garden corner.
If you’ve been wondering whether you can plant lavender with citronella, the short answer is yes, but there’s a bit of nuance to getting them to thrive together.
The reason people often ask can you plant lavender with citronella comes down to their shared reputation for repelling mosquitoes and adding sensory appeal to outdoor spaces.
In this post, we’ll explore exactly how you can plant lavender with citronella successfully, what conditions each plant loves, and where they might clash so you can avoid common pitfalls.
Let’s dig into the details of pairing these two aromatic champions.
Yes, You Can Plant Lavender With Citronella—Here’s Why
The truth is, you can plant lavender with citronella, and they actually make surprisingly good bedfellows if you respect their individual quirks.
Both plants crave plenty of sunshine, which is the first big win when you’re planning to plant lavender with citronella side by side.
They also share a love for well-draining soil, so you won’t need to create wildly different planting zones for each one.
When you plant lavender with citronella, you’re also doubling down on natural mosquito repellency, since both release aromatic oils that bugs tend to avoid.
That means your patio or garden path becomes a dual-defense zone just by combining these two species.
However, to really succeed, it helps to know what you’re working with before you plant lavender with citronella in the same bed.
1. Lavender Loves Lean, Alkaline Soil
Lavender is a Mediterranean native that thrives in poor, gritty, slightly alkaline soil.
It hates rich, soggy ground, and too much organic matter can actually shorten its lifespan.
So when you plant lavender with citronella, you’ll want to keep the lavender’s roots from sitting in heavy compost.
Instead, think sandy or gravelly loam with a pH around 6.5 to 7.5 for the best results.
Lavender also prefers infrequent deep watering over frequent light sprinkles, so don’t drown it just because its neighbor is thirsty.
2. Citronella Is More Thirsty and Forgiving of Rich Soil
Now, citronella (which is actually a scented geranium or a true grass, depending on the variety) tends to prefer slightly richer, moister soil.
It’s more forgiving of organic matter and won’t sulk if you mix in some compost when you plant lavender with citronella together.
That said, citronella still hates waterlogged roots, so drainage remains non-negotiable for both plants.
If you’re growing the true citronella grass (Cymbopogon nardus), it will need more water than lavender, especially during hot summer months.
So when you plant lavender with citronella, plan to water toward the citronella’s base and keep the lavender’s crown dry to avoid rot.
Best Practices for Planting Lavender With Citronella
To make sure both plants flourish, you need to be strategic about spacing, container choice, and garden placement.
Here’s how to get it right when you decide to plant lavender with citronella in the ground or in pots.
1. Give Them Enough Breathing Room
Lavender plants can spread 2 to 3 feet wide, while citronella grasses or geraniums can reach similar or larger sizes.
If you plant lavender with citronella too close together, they’ll compete for airflow, which invites fungal issues like powdery mildew.
A good rule of thumb is 18 to 24 inches between plants, depending on the mature width of your specific cultivars.
Proper spacing also ensures both plants get even sun exposure, so neither one shades the other out.
2. Choose a Sunny, Sheltered Spot
Both lavender and citronella want at least 6 to 8 hours of direct sunlight each day.
So pick the sunniest corner of your yard when you plant lavender with citronella.
Shelter from strong winds is also helpful because harsh gusts can dry out lavender’s foliage and stress citronella’s broad leaves.
A south-facing wall or a spot near a sunny fence line works brilliantly for this pairing.
3. Consider Containers for Easier Management
If you’re worried about differing water needs, you can plant lavender with citronella in separate large pots while keeping them visually grouped.
Each plant gets its own watering schedule, yet they still create a combined mosquito-repelling display on your deck.
Use unglazed terracotta pots for lavender to help wick away excess moisture, and a slightly larger plastic or glazed pot for citronella to retain a touch more water.
Just ensure every container has drainage holes, and you’ll sidestep the biggest killer of both plants: root rot.
Potential Challenges When You Plant Lavender With Citronella
While it’s totally doable, there are a few hiccups you might run into when combining these two.
Understanding these issues ahead of time keeps your garden happy and your plants vigorous.
1. Overwatering Lavender Is the Number One Mistake
The main risk when you plant lavender with citronella is accidentally overwatering the lavender while trying to satisfy the citronella.
If you see yellowing leaves or a mushy base on your lavender, that’s a clear cry for less water.
To fix this, water deeply but rarely, and always let the top inch or two of soil dry out completely between waterings.
You can also mound the soil slightly around lavender to improve drainage at the crown level.
2. Winter Hardiness Differs Between the Two
Lavender is generally hardy in zones 5 through 9, while true citronella grass is a tropical plant that won’t survive frost outdoors.
So if you live in a colder climate, you can plant lavender with citronella during the warm season, but you’ll need to bring citronella indoors before the first freeze.
Container gardening makes this transition much simpler, so you can just wheel the pot inside when temperatures drop.
Lavender can stay put through winter in many regions, especially if you mulch lightly around its roots.
3. Pest Pressure Can Shift if You Overfertilize
Both plants naturally repel mosquitoes, but if you overfeed them with nitrogen-rich fertilizer, you’ll push out tender new growth that attracts aphids.
When you plant lavender with citronella, skip heavy feeding altogether.
Instead, top-dress with a thin layer of compost once in spring, and let lean conditions do the rest.
Healthy, slightly stressed plants produce more of the aromatic oils that keep pests away.
So, Can You Plant Lavender With Citronella?
Yes, you can plant lavender with citronella, and it’s a winning combination for a sunny, low-maintenance garden space.
The key lies in managing their slight differences in water and soil preferences, while giving them both full sun and excellent drainage.
When you plant lavender with citronella in the ground, space them well and water at the base of each plant separately.
When you plant lavender with citronella in pots, you gain the flexibility to adjust moisture levels and move them indoors for winter.
Either way, you’ll create a gorgeous, fragrant pairing that works overtime to keep mosquitoes at bay.
So go ahead and plant lavender with citronella together, your patio will thank you, and so will your skin.
