Can You Plant Basil And Peppermint Together

Yes, you can plant basil and peppermint together, but only if you understand their different growth habits and keep a few key rules in mind.
 
Planting basil and peppermint together is a question many gardeners ask because both herbs are so useful in the kitchen.
 
While they can share a garden bed, peppermint’s aggressive spreading nature can easily overtake basil if you’re not careful.
 
The good news is that with proper spacing, container choices, and a little planning, basil and peppermint can coexist beautifully.
 
In this post, we’ll break down exactly how to plant basil and peppermint together successfully, what to watch out for, and the best companion planting strategies.
 
Let’s dig in and get your herb garden thriving.
 

Why You Can Plant Basil And Peppermint Together (With Care)

You can plant basil and peppermint together because they share similar sunlight and watering needs, but their root systems tell a different story.
 
Basil has a shallow, compact root system that stays neatly where you put it.
 
Peppermint, on the other hand, sends out runners called stolons that spread horizontally and aggressively.
 
This means when you plant basil and peppermint together in open ground, the peppermint will quickly invade basil’s space and steal nutrients.
 
The trick is to manage peppermint’s growth so both herbs can thrive side by side.
 

1. Peppermint Is a Spreading Champion

Peppermint spreads so fast that it’s often called invasive in garden settings.
 
If you plant basil and peppermint together directly in the soil, the peppermint’s roots will wrap around basil’s roots within weeks.
 
This root competition stresses basil, which prefers consistent, undisturbed soil.
 
Basil’s leaves may yellow or stunt if peppermint crowds out its root zone.
 
So while you can plant basil and peppermint together, you must contain the peppermint first.
 

2. Both Love Sun and Moisture

The good news is that basil and peppermint both crave full sun to partial shade.
 
They also like consistently moist, well-draining soil with a slightly acidic to neutral pH.
 
This shared preference makes it easy to water and fertilize them the same way.
 
When you plant basil and peppermint together, you won’t need separate watering schedules or different soil mixes.
 
That’s a big win for busy gardeners who want low-maintenance herbs.
 

3. Their Scents Complements Each Other

Some gardeners worry that planting basil and peppermint together will muddy their flavors, but that’s not the case.
 
The essential oils in each plant remain distinct, so your basil will still taste like basil and your peppermint like peppermint.
 
In fact, the strong aroma of peppermint can help repel certain pests that might bother basil, like aphids and spider mites.
 
This makes planting basil and peppermint together a natural pest management strategy.
 

Best Ways To Plant Basil And Peppermint Together

Now that you know you can plant basil and peppermint together, let’s talk about the smartest ways to do it.
 
The method you choose depends on whether you have a garden bed, raised bed, or only pots.
 

1. Use a Sunken Container for Peppermint

The classic trick is to plant peppermint in a pot with drainage holes, then bury that pot in the garden bed.
 
This keeps peppermint’s runners contained while still allowing water to flow through.
 
You can plant basil around the outside of that buried pot without fear of root invasion.
 
This way, you really can plant basil and peppermint together in the same bed, just with a barrier between their roots.
 

2. Grow Them in Separate Pots Side by Side

If you want the simplest solution, just use two pots placed next to each other.
 
You can plant basil and peppermint together visually, but each stays in its own container.
 
This completely eliminates any risk of peppermint choking out basil.
 
Plus, you can move the pots around to catch the best sunlight throughout the day.
 
Container gardening is perfect for balconies, patios, or small yards.
 
Just make sure each pot has good drainage and use a quality potting mix.
 

3. Choose a Large, Wide Planter

You can also plant basil and peppermint together in one big container, but you’ll need to prune peppermint regularly.
 
Choose a planter that’s at least 18 inches wide and 12 inches deep.
 
Give each herb its own section, and trim peppermint back hard every few weeks.
 
This prevents the peppermint from dominating the planter.
 
Keep a pair of scissors handy and you’ll manage fine.
 

Key Care Tips When You Plant Basil And Peppermint Together

Once you’ve got your setup ready, you’ll need to maintain both herbs properly.
 
Here are the most important care points to remember.
 

1. Water Consistently But Don’t Overdo It

Both basil and peppermint like evenly moist soil, but they hate sitting in water.
 
Water deeply when the top inch of soil feels dry to the touch.
 
If you’re using a buried container for peppermint, check that its drainage holes don’t get clogged.
 
Proper drainage is critical when you plant basil and peppermint together because soggy roots lead to rot.
 

2. Fertilize Lightly Every Few Weeks

Peppermint is a light feeder, and basil doesn’t need heavy fertilization either.
 
A balanced liquid fertilizer diluted to half strength works great.
 
Apply it every three to four weeks during the growing season.
 
Too much fertilizer makes basil grow leggy and reduces its essential oil concentration.
 
So keep it simple and your plants will thank you.
 

3. Prune Both Herbs Regularly

Pruning is essential when you plant basil and peppermint together.
 
For basil, pinch off the top leaves to encourage bushier growth.
 
For peppermint, cut back whole stems to keep it from sprawling and getting woody.
 
Never let peppermint flower unless you want to collect the seeds.
 
Once peppermint flowers, its leaf flavor drops, and it focuses energy on seed production.
 
Regular harvesting keeps both herbs productive all season long.
 

4. Watch Out for Shared Pests

While peppermint repels some pests, both herbs can attract spider mites in hot, dry weather.
 
Check the undersides of leaves regularly.
 
A strong spray of water from the hose can knock off mites and aphids.
 
Neem oil is a safe organic remedy if infestations get serious.
 
Keeping air circulating around the plants helps prevent most pest problems.
 

What Not To Do When You Plant Basil And Peppermint Together

Avoid these common mistakes so your herbs stay healthy and happy.
 
First, never plant peppermint directly into an open ground bed without a barrier.
 
It will take over your entire garden within one season.
 
Second, don’t plant basil and peppermint together in a small pot that’s less than 12 inches wide.
 
Cramped roots stress both plants and reduce yields.
 
Third, don’t let peppermint dry out completely.
 
While it’s drought tolerant once established, young peppermint needs steady moisture.
 
And finally, don’t plant basil and peppermint together near fennel.
 
Fennel releases chemicals that inhibit the growth of many herbs, including basil.
 
Keep fennel far away from your herb garden.
 

So, Can You Plant Basil And Peppermint Together?
