Yes, you can plant mint with lavender, but it requires careful planning since these two herbs have very different growing habits and needs.
If you’ve been wondering whether planting mint and lavender together is a good idea, the short answer is that it’s possible with the right setup, though it’s not always the simplest companion planting choice.
Mint is a vigorous, spreading perennial that loves moisture and rich soil, while lavender thrives in dry, well-drained, lean soil with plenty of sun.
You can plant mint with lavender successfully by using containers or physical barriers to keep mint’s aggressive roots from taking over lavender’s space.
In this post, we’ll explore whether you can plant mint with lavender, the challenges you’ll face, and the best strategies to make these two herbs coexist happily.
Let’s dig into the details of planting mint and lavender together.
Why You Can Plant Mint With Lavender (With Caveats)
You can plant mint with lavender if you address the core differences between them, but you must first understand why these herbs clash.
Mint is a fast-growing creeper that sends out runners called stolons, which can quickly colonize an entire garden bed.
Lavender, on the other hand, is a slow-growing woody shrub that prefers to stay dry and undisturbed at its roots.
When you plant mint with lavender directly in the ground, mint’s rampant growth can smother lavender’s shallow roots and steal nutrients and water.
But that doesn’t mean you can’t plant mint with lavender at all, it just means you need to give each plant what it wants.
1. Soil Preferences Are Opposite but Manageable
Mint thrives in consistently moist, fertile soil with a slightly acidic to neutral pH.
Lavender desperately needs gritty, alkaline soil that drains instantly and never stays soggy.
If you try to plant mint with lavender in the same soil without adjustment, one will suffer, usually lavender if the soil stays too wet.
To make it work, you can amend the planting area with coarse sand or perlite to improve drainage for lavender.
Then, create a separate moisture zone for your mint by watering it specifically while letting the lavender dry out between waterings.
This way, you can plant mint with lavender in the same general area, but each herb receives its own tailored care.
2. Sunlight Requirements Align Well
Both mint and lavender love full sun, so that’s a point in your favor when you plant mint with lavender.
Mint will tolerate partial shade, but it grows more lush and flavorful with at least six hours of direct sunlight each day.
Lavender absolutely demands full sun, meaning eight or more hours daily, to produce fragrant oils and avoid leggy, weak growth.
Because they both need bright, sunny spots, you won’t have to compromise on location when you plant mint with lavender.
Just be sure to place lavender where it gets the intense afternoon sun, and mint can sit slightly to the side or behind it.
3. Watering Routines Must Be Separated
The biggest challenge when you plant mint with lavender is figuring out how to water them separately.
Mint wants its soil to stay evenly moist, almost like a sponge that never fully dries out.
Lavender prefers bone-dry conditions between waterings, and overwatering is the number one killer of lavender plants.
If you plant mint with lavender in the same bed and water them the same way, lavender will likely develop root rot.
Instead, consider planting mint in a pot that is sunk into the ground near the lavender.
This lets you water the mint pot frequently while the surrounding ground stays dry for lavender.
You can also install a drip line that only waters the mint zone and keep lavender completely off that schedule.
Best Ways to Plant Mint With Lavender Successfully
If you’re ready to attempt planting mint and lavender together, there are a few proven methods that work well.
The key is always to contain mint while giving lavender its preferred dry, airy environment.
Here are the top strategies to consider when you want to plant mint with lavender.
1. Use Containers for Both Plants
The simplest way to plant mint with lavender is to keep them in separate containers placed side by side.
Choose a wide, shallow pot for mint that allows its runners to spread without escaping.
Select a deep, terracotta pot for lavender, which helps wick moisture away from its roots.
Place both pots together on a sunny patio or balcony, and you’ve effectively planted mint with lavender as companions.
This method also gives you complete control over soil, water, and fertilizer for each herb individually.
It’s honestly the most foolproof approach for beginners who worry about managing these different needs.
2. Bury a Mint Container in the Ground
Another clever trick is to plant mint in a large pot with no drainage holes, then bury that pot up to its rim near lavender.
This physical barrier stops mint roots from escaping while still making it look like they’re growing together.
You can plant mint with lavender this way and water the buried mint pot directly, keeping the surrounding soil dry.
Just make sure the buried pot has enough room for mint to grow and isn’t too small, or mint will become root-bound quickly.
You should also leave the pot’s rim slightly above soil level so that mint runners can’t crawl over the top.
3. Install a Root Barrier Around Mint
If you prefer planting mint directly in the ground, you can install a sturdy root barrier to contain it.
Dig a trench at least 12 to 18 inches deep around the mint’s designated area.
Line the trench with a heavy-duty plastic or metal barrier that stands above the soil surface by a few inches.
Then, you can plant mint within that confined zone and lavender just outside of it.
Because you can plant mint with lavender this way, you’ll still enjoy their visual companionship without the takeover.
Check the barrier every spring for cracks or gaps, since mint is relentless about finding escape routes.
4. Choose Less Invasive Mint Varieties
Not all mint is created equal when it comes to aggressiveness.
While most mints spread vigorously, certain varieties like strawberry mint or apple mint are slightly less invasive.
You can plant mint with lavender using these tamer types and give yourself more breathing room.
However, even less aggressive mints will still spread, so don’t skip containment measures completely.
If you absolutely love a specific type like peppermint or spearmint, just assume it will be very invasive.
Always default to containers or barriers when you plant mint with lavender, regardless of the mint variety.
Potential Problems When You Plant Mint With Lavender
Even with the best intentions, you might face some issues when you plant mint with lavender in close quarters.
Knowing these pitfalls ahead of time helps you prepare and adjust your gardening strategy.
1. Competition for Nutrients
Mint is a hungry feeder and will quickly absorb available nitrogen, potassium, and phosphorus from the soil.
When you plant mint with lavender nearby, lavender may show signs of nutrient deficiency, like yellowing leaves.
To avoid this, fertilize mint lightly with a balanced organic feed a few times during the growing season.
Don’t fertilize lavender at all, as it prefers poor soils and extra nutrients can cause floppy, weak growth.
2. Spread of Pests and Diseases
Mint is vulnerable to rust, a fungal disease that produces orange spots on leaves and can spread to neighboring plants.
Lavender is largely pest-free, but it can suffer from root rot if mint’s frequent watering keeps the area damp.
When you plant mint with lavender, inspect both plants regularly for signs of trouble.
Space them far enough apart that mint foliage doesn’t touch lavender stems, which reduces disease transmission.
And always water at the base of mint, not overhead, to keep its leaves dry and fungus-resistant.
3. Shading and Airflow Issues
Mint can grow tall and bushy, potentially shading out lavender that needs unrestricted sunlight.
Lavender also values good airflow around its stems to prevent fungal issues and promote healthy wood formation.
If you plant mint with lavender too closely, mint’s dense leaves can trap humidity around lavender.
To solve this, prune mint frequently to keep it low and tidy, cutting it back by one-third every few weeks.
Position lavender on the sunniest, breeziest side so that mint never blocks its light or air circulation.
So, Can You Plant Mint With Lavender?
Yes, you can plant mint with lavender, but only when you take deliberate steps to manage their conflicting needs.
Whether you use separate pots, bury a mint container, or install root barriers, you can enjoy both herbs together.
Remember that successful companion planting means respecting each plant’s preferences, not forcing them to share everything.
With proper spacing, controlled moisture, and regular monitoring, planting mint and lavender together is totally achievable.
And the reward is worth the effort, because fresh mint for tea and fragrant lavender for sachets make a wonderful garden duo.
So go ahead and plant mint with lavender using the tips we’ve covered, and you’ll have a thriving, aromatic garden.
Happy gardening, and may your mint stay contained while your lavender basks in the sun.
