You can plant lavender with mint, but it’s not the best idea for a long-term companion planting match.
Both herbs are incredibly popular in gardens, and it’s easy to see why you’d want them together.
But when you plant lavender with mint, you’re mixing two plants with very different needs and growth habits.
In this post, we’ll dig into why you can plant lavender with mint in some situations, the serious problems that arise, and what you should do instead if you want both to thrive.
Let’s get those gardening gloves on and sort this out.
Why You Can Plant Lavender With Mint (But Probably Shouldn’t)
So, can you plant lavender with mint and expect a happy garden bed?
Technically, yes, you can plant lavender with mint because neither plant will poison the other or immediately die.
However, planting lavender with mint in the same soil is like putting a desert cactus next to a rainforest fern.
They just want completely different environments.
Let me explain the core reasons why this pairing is tricky.
1. Watering Needs Are Complete Opposites
Lavender is a Mediterranean plant that craves dry, sandy, and well-draining soil.
It hates wet feet and will develop root rot if the soil stays damp for too long.
Mint, on the other hand, is a moisture lover that thrives in rich, consistently damp soil.
If you water enough to keep mint happy, your lavender will suffer.
If you keep the soil dry enough for lavender, your mint will wilt and become crispy.
So, if you plant lavender with mint, you’re constantly fighting this water battle.
2. Mint Is an Aggressive Spreader
Mint doesn’t just sit politely where you place it.
It sends out underground runners called rhizomes that shoot in every direction.
When you plant lavender with mint in an open garden bed, mint will quickly invade the lavender’s space.
This aggressive growth will crowd out the lavender’s roots and steal nutrients and water.
Lavender grows slowly and likes its personal space, so mint will absolutely overwhelm it.
3. Soil pH and Fertility Clash
Lavender prefers alkaline soil with a pH between 6.5 and 7.5, and it actually thrives in poor, lean soil.
Fertile soil makes lavender grow floppy and less fragrant.
Mint loves rich, fertile, and slightly acidic to neutral soil, so it wants regular feeding and compost.
If you plant lavender with mint and add compost for the mint, you’re reducing lavender’s essential oil production.
Those two soil preferences just don’t line up well.
When You Plant Lavender With Mint, How Do You Make It Work?
Okay, so maybe you really love both herbs and you’re wondering if you can plant lavender with mint anyway.
Here’s the good news: yes, you can plant lavender with mint if you use separate containers.
Container gardening solves almost every problem this pairing creates.
1. Use Separate Pots for Each Herb
If you want both, give each plant its own pot with its own specialized soil mix.
Use a gritty, sandy, and fast-draining mix for lavender.
Use a standard potting mix that holds moisture for your mint.
By keeping them separate, you can water each one according to its needs.
That way, you can plant lavender with mint in the same general area, like a balcony or patio, without them fighting.
2. Bury Mint in a Pot Within the Ground
If you have to plant them in the same garden bed, you can try the buried pot trick.
Plant your mint inside a large, bottomless container buried in the soil.
This acts as a barrier to stop those wild runners from escaping.
Place the lavender at a good distance, at least two feet away, from the buried mint.
Even with this barrier, you’ll still need to water carefully, so monitor the lavender closely for signs of overwatering.
3. Choose the Right Location and Sunlight
Both lavender and mint enjoy full sun, so that part is easy.
Aim for at least six hours of direct sunlight daily for both.
However, mint can tolerate a little afternoon shade, while lavender needs all the sun it can get.
If you plant lavender with mint in a spot that gets too much shade, the lavender will weaken, and the mint will still grow fine.
So, pick the sunniest spot you have and prioritize the lavender’s needs.
Benefits of Growing Lavender and Mint Together
Despite all the downsides, some gardeners still want to plant lavender with mint because there are actual benefits.
Let’s look at the positives so you can make an informed decision.
1. Pest Deterrent Power
Both lavender and mint have strong essential oils that repel many common garden pests.
Aphids, fleas, moths, and mosquitoes all hate these strong scents.
Having both herbs nearby (even in pots) can create a protective aromatic barrier for your other vegetables.
So, you can plant lavender with mint strategically around your garden for pest control, just not in the same soil.
2. Attracting Pollinators
Lavender is a bee magnet, and mint flowers also attract beneficial pollinators like butterflies and hoverflies.
When you plant lavender with mint in the same general vicinity, you’ll create a buzz of activity.
More pollinators in your garden means better fruit set on your tomatoes, squash, and berries.
Just keep them close, but not intertwined, and you’ll get this perk.
3. Maximizing Small Garden Spaces
If you have a tiny garden, you might want to plant lavender with mint to save space.
Using vertical planters or tiered pots lets you keep both herbs in a small footprint.
Place lavender in a taller pot and mint in a hanging basket below it.
This meets the “can you plant lavender with mint” requirement while respecting each plant’s boundaries.
The Best Companion Plants for Lavender and Mint
If you’re ready to give up on mixing these two, don’t worry.
Plenty of other herbs make much better neighbors for each plant.
1. Great Companions for Lavender
Instead of mint, pair lavender with rosemary, thyme, sage, or oregano.
These Mediterranean herbs share the same love for dry, sunny, and poor soil.
They all have similar watering needs, so you can plant them together without stress.
Roses also love lavender, and they look stunning together.
2. Great Companions for Mint
Mint gets along famously with brassicas like cabbage and kale.
It also helps repel pests from tomatoes and peppers.
Other moisture-loving herbs like parsley and chervil can coexist with mint.
Remember to always keep mint contained, even with these friendly companions.
So, Can You Plant Lavender With Mint?
So, can you plant lavender with mint in your garden?
Yes, you can plant lavender with mint, but only if you use separate containers or heavy barriers to prevent root wars.
The truth is, planting lavender with mint directly in the ground will almost always lead to a sad lavender plant and a runaway mint invasion.
Their watering needs, soil pH, and growth habits are simply too different for a harmonious shared bed.
If you want both herbs to flourish, give each plant its own home and place the pots side by side.
That way, you can enjoy the pest-repelling benefits and the lovely scents without the gardening headache.
Happy planting, and remember to respect those mint runners!
