Yes, you can plant basil and cilantro together, and they make surprisingly good garden companions when you understand their needs.
If you’ve been wondering whether you can plant basil and cilantro together in the same pot or garden bed, the short answer is absolutely, but there are a few important details to get right.
You can plant basil and cilantro together because they share similar soil preferences and watering needs, even though their sunlight requirements differ a bit.
In this post, we’ll explore why you can plant basil and cilantro together, the best way to set them up for success, and the common mistakes to avoid when growing these two herbs side by side.
Let’s dig in.
Why You Can Plant Basil and Cilantro Together
You can plant basil and cilantro together for several practical reasons, and once you understand them, you’ll see why this pairing is such a favorite among home gardeners.
1. They Share Similar Soil and Water Preferences
Both basil and cilantro thrive in well-draining soil that’s kept consistently moist but not waterlogged.
When you plant basil and cilantro together, you can use the same potting mix or garden soil amendment, which simplifies your gardening routine.
Aim for a soil pH between 6.0 and 7.0, and both herbs will be perfectly happy.
Watering is where this pairing really shines because both herbs appreciate regular, even moisture without drying out completely between waterings.
So if you’re someone who tends to forget to water, planting basil and cilantro together actually helps because they’ll both remind you with droopy leaves when they need a drink.
2. Basil Can Provide Light Shade for Cilantro
Cilantro is a cool-season herb that tends to bolt (go to seed) quickly in hot afternoon sun.
Meanwhile, basil loves the warmth and can handle full sun without any issues.
When you plant basil and cilantro together, the taller basil plants can offer a bit of dappled shade to the cilantro during the hottest part of the day.
This natural shading helps keep cilantro cooler and slows down that frustrating bolting process.
Just make sure the basil isn’t so tall that it completely blocks the sun, because cilantro still needs about four to six hours of light each day.
3. They Deter Some Pests When Grown Together
Basil’s strong, aromatic oils are known to repel certain insects like aphids, spider mites, and even mosquitoes.
Cilantro attracts beneficial insects like ladybugs and lacewings that feed on common garden pests.
So when you plant basil and cilantro together, you create a mini ecosystem where basil keeps bad bugs away and cilantro invites the good bugs in.
This natural pest control is a big reason why so many gardeners love this combination.
4. You Get Two Culinary Staples From One Space
If you love cooking, you already know how often recipes call for both fresh basil and fresh cilantro.
Planting basil and cilantro together means you can step outside and snip both herbs for salsas, pestos, curries, salads, and stir-fries without wasting any space.
It’s a practical choice that maximizes your harvest and keeps your kitchen stocked with fresh flavors all season long.
How to Plant Basil and Cilantro Together Successfully
Now that you know you can plant basil and cilantro together, let’s talk about the best way to actually do it so both herbs thrive.
1. Choose the Right Container or Garden Spot
If you’re planting in a pot, choose one that’s at least 12 inches wide and 10 inches deep.
This gives both root systems enough room to spread out without competing too much.
In a garden bed, space your basil and cilantro plants about 6 to 8 inches apart so they have breathing room.
Remember that cilantro has a taproot, so it doesn’t like being transplanted once it’s established, which means starting seeds directly in the final container is often the easiest route.
2. Time Your Planting Wisely
Because cilantro prefers cooler weather and basil loves heat, the timing matters when you want to plant basil and cilantro together.
The best approach is to plant cilantro in early spring or late summer, then add basil a few weeks later once the soil has warmed up.
Alternatively, you can plant them at the same time in a spot that gets morning sun and afternoon shade, which keeps cilantro happy while still giving basil enough warmth.
If you live in a hot climate, consider planting them together in a location that gets some afternoon shade to protect the cilantro.
3. Use the Right Fertilizer Strategy
Both basil and cilantro are light feeders, so you don’t need heavy fertilization.
When you plant basil and cilantro together, just mix some compost into the soil before planting, and that’s usually enough.
If you want to give them a boost, use a balanced organic fertilizer once a month at half strength.
Avoid high-nitrogen fertilizers because they’ll make basil grow big leaves but reduce the essential oils that give it flavor, and they’ll make cilantro grow tall and leggy instead of lush and leafy.
4. Harvest Regularly to Keep Them Productive
The secret to keeping basil and cilantro growing well together is consistent harvesting.
Pinch off basil leaves from the top to encourage bushier growth, and always remove any flower buds before they open.
For cilantro, cut the outer leaves first and leave the inner ones to keep producing.
When cilantro starts to bolt, just let it go to seed and collect the coriander seeds for your spice rack.
Then you can plant fresh cilantro in the same spot while the basil keeps going strong.
Common Mistakes When You Plant Basil and Cilantro Together
Even though you can plant basil and cilantro together, there are a few pitfalls that can trip up new gardeners.
1. Overcrowding the Plants
Cramming too many plants into one container is the most common mistake.
When you plant basil and cilantro together, both herbs need airflow to prevent fungal diseases like powdery mildew.
Give them enough space and don’t be afraid to thin out seedlings so the strongest ones can thrive.
2. Ignoring the Temperature Difference
While basil thrives in temperatures above 70°F, cilantro prefers cooler conditions between 50°F and 70°F.
When you plant basil and cilantro together, you need to find a middle ground, which usually means partial shade or planting during milder seasons.
If you notice cilantro bolting quickly, that’s a sign it’s too hot, so move your container to a shadier spot or add a shade cloth.
3. Forgetting to Prune Basil
Basil grows fast, and if you don’t prune it regularly, it’ll shade out the cilantro completely.
When you plant basil and cilantro together, make a habit of trimming basil every couple of weeks.
Not only does this keep the plant compact, but it also prevents flowering and keeps the leaves tender and flavorful.
So, Can You Plant Basil and Cilantro Together?
You can plant basil and cilantro together, and it’s an excellent choice for both beginner and experienced gardeners.
The key is to give them the right soil, water them consistently, manage the sunlight so cilantro doesn’t bolt, and harvest both regularly.
When you plant basil and cilantro together, you get a beautiful, productive container garden that supplies fresh herbs all season long.
Whether you’re making a caprese salad with basil or a fresh salsa with cilantro, you’ll be glad you grew them side by side.
So go ahead, grab some seeds, and get started, because planting basil and cilantro together is one of the smartest moves you can make in your herb garden.
