Do Basil And Cilantro Grow Well Together

Basil and cilantro do grow well together, and it’s a pairing that makes perfect sense for both your garden and your kitchen.
 
If you’ve been wondering whether basil and cilantro grow well together, the short answer is yes, as long as you understand their individual needs and make a few simple adjustments.
 
These two beloved herbs are often found side by side in salsas, pestos, and fresh summer salads, so it’s natural to want them thriving in the same bed or container.
 
In this post, we’ll dig into why basil and cilantro grow well together, the best way to plant them as companions, and the common mistakes to avoid so both herbs stay happy and productive.
 
Let’s get started.
 

Why Basil and Cilantro Grow Well Together

Basil and cilantro grow well together because they share similar sunlight and watering preferences, but they also complement each other in a way that maximizes your harvest.
 
The key is that neither plant is overly aggressive, meaning they won’t compete for root space in a way that hurts the other.
 
Let’s break down the specific reasons this duo works so well.
 

1. They Both Love Full Sun, With a Small Caveat

When you plant basil and cilantro together, both herbs thrive in full sun, which means around six to eight hours of direct light each day.
 
Basil is a heat lover and will soak up all the sun you can give it, but cilantro has a slightly trickier relationship with heat.
 
Cilantro tends to bolt, or go to seed, quickly when temperatures soar above 75°F (24°C), which is why basil and cilantro grow well together if you provide a little afternoon shade for the cilantro.
 
If you’re planting in a garden bed, place cilantro on the east side of your basil so it gets morning sun and some relief from the harsh afternoon rays.
 
In a container, you can position the basil to provide a natural shade canopy over the cilantro as it grows taller.
 

2. Complementary Watering Needs

Basil and cilantro grow well together because they both prefer consistently moist soil, which makes watering a breeze.
 
Neither herb likes to dry out completely, and both will wilt dramatically if you forget to water them.
 
Aim to keep the soil evenly damp but not waterlogged, and you’ll see both herbs reward you with lush, fragrant leaves.
 
One trick is to add a layer of mulch around the base of both plants, which helps lock in moisture and keeps the cilantro’s roots cooler during warm spells.
 

3. Ideal Soil Conditions Are Nearly Identical

As long as you use rich, well-draining soil with a pH between 6.0 and 7.0, basil and cilantro grow well together without issue.
 
Both herbs appreciate a good amount of organic matter mixed in, like compost or aged manure, which provides a slow release of nutrients throughout the growing season.
 
This means you don’t have to create separate planting zones, a single prepared bed works perfectly for both.
 

4. They Attract Different Beneficial Insects

Another reason basil and cilantro grow well together is their ability to attract a diverse group of beneficial insects.
 
Basil is known for repelling certain pests like thrips and mosquitoes, while cilantro’s delicate flowers are a magnet for hoverflies and parasitic wasps that eat aphids.
 
This natural pest control duo means your garden will be healthier overall, and you’ll spend less time battling bugs.
 

Best Practices for Growing Basil and Cilantro Together

To ensure basil and cilantro grow well together, you need a few practical strategies that address their different growth rates and life cycles.
 
Here’s how to set them up for success.
 

1. Plant Cilantro First, Then Basil

Cilantro has a much shorter lifespan than basil, especially in warmer climates, so you’ll want to stagger your planting.
 
Sow cilantro seeds directly in the soil about three to four weeks before you transplant your basil seedlings.
 
This way, the cilantro gets a head start and can be harvested before the basil grows large enough to overshadow it completely.
 
Basil and cilantro grow well together when you use this succession planting approach, as it ensures a continuous harvest of both herbs throughout the season.
 

2. Give Them Enough Space to Breathe

While basil and cilantro grow well together, they still need their own space to avoid crowding.
 
Basil can grow up to two feet tall and wide, while cilantro stays more compact, reaching about 12 to 18 inches.
 
Plant basil about 12 to 18 inches apart and cilantro about 6 to 8 inches apart, but interplant them in rows rather than mixing them in the same hole.
 
This spacing ensures good airflow, which reduces the risk of fungal diseases like powdery mildew that can strike when leaves stay wet and cramped.
 

3. Use a Container for Easier Management

If you’re short on garden space, a large container is a fantastic way to help basil and cilantro grow well together.
 
Choose a pot that’s at least 12 inches deep and wide enough to fit both plants with a few inches of space between them.
 
Place the basil in the center and cilantro around the edges, so you can easily trim each herb without disturbing the other’s roots.
 
Container growing also lets you move the pot to a shadier spot during heatwaves, which is something cilantro will genuinely thank you for.
 

4. Fertilize Lightly and Regularly

Basil and cilantro grow well together when they get consistent but gentle feeding.
 
Too much fertilizer, especially high-nitrogen formulas, will make basil grow huge leaves that lack flavor, while cilantro will shoot up tall and bolt even faster.
 
Instead, use a balanced liquid fertilizer diluted to half strength every two to three weeks.
 
This keeps both herbs growing steadily without sacrificing the essential oils that give them their wonderful aromas.
 

Common Mistakes to Avoid With These Two Herbs

Even though basil and cilantro grow well together, there are a few pitfalls that can turn this perfect pairing into a frustrating mess.
 
Avoid these common errors, and you’ll keep both herbs thriving.
 

1. Letting Cilantro Bolt Before You Harvest

The biggest mistake gardeners make is letting cilantro flower and go to seed too early.
 
Once cilantro bolts, the leaves turn bitter and tough, and the plant stops producing new growth.
 
To prevent this, harvest cilantro regularly by snipping the outer leaves first, and keep the plant trimmed back to encourage bushier regrowth.
 
And remember, even though basil and cilantro grow well together, cilantro will still bolt if it gets too hot, so shade is your friend.
 

2. Overwatering Basil to Keep Cilantro Happy

Since basil and cilantro grow well together in moist soil, some gardeners accidentally overwater.
 
Basil is actually a bit more drought-tolerant than cilantro, and soggy roots can cause basil to develop root rot or fungal leaf spots.
 
The solution is to water deeply but less frequently, letting the top inch of soil dry out slightly between waterings.
 
Check the soil with your finger, and only water when it feels dry to the touch.
 

So, Do Basil and Cilantro Grow Well Together?

Basil and cilantro do grow well together, but the process isn’t entirely hands-off.
 
Certain conditions help these herbs flourish side by side, while other factors like heat, overcrowding, or inconsistent watering can lead to disappointment.
 
We’ve covered why basil and cilantro grow well together, the best planting techniques, and the mistakes to avoid, so you’re now fully equipped to give this dynamic duo the care they need.
 
Whether you’re using a garden bed or a sunny windowsill pot, this pairing will reward you with fresh, aromatic leaves all season long.
 
So go ahead and plant basil and cilantro together, and enjoy the convenience of stepping outside to grab both herbs for your next meal.
 
Happy gardening, and here’s to a bountiful harvest of these two wonderful companions.
