Basil and thyme grow well together because they share very similar growing requirements that make them excellent companion plants.
These two Mediterranean herbs thrive in the same sunny, well-drained conditions, which means you can plant them side by side in the same bed or even in the same container with great success.
If you’ve been wondering whether basil and thyme grow well together, the short answer is yes, and they can actually benefit each other when grown in close proximity.
Not only do basil and thyme grow well together in terms of their soil and sunlight preferences, but they also offer each other natural pest deterrent benefits that keep your herb garden healthier.
In this post, we’ll dig into why basil and thyme grow well together, the best ways to plant them as companions, and a few simple tips to get the most out of this dynamic duo.
Let’s jump right into the dirt.
Why Basil and Thyme Grow Well Together
Basil and thyme grow well together primarily because they come from similar native environments and have matching cultivation needs.
Both plants originate from the Mediterranean region, where they’ve adapted to hot, sunny summers and dry, rocky soils with excellent drainage.
This shared heritage means basil and thyme grow well together without competing for resources, and they naturally complement each other’s growth habits.
Below are the main reasons why this pairing works so beautifully.
1. They Share Identical Sunlight Needs
The most obvious reason basil and thyme grow well together is their love for full sun.
Both herbs need at least six to eight hours of direct sunlight each day to produce those aromatic, flavorful leaves you love to cook with.
When you plant basil and thyme together in a sunny spot, you don’t have to worry about one overshadowing the other or stealing light from its friend.
Because basil and thyme grow well together in full sun, they both receive exactly what they need without any competition.
This makes planning your garden layout simple, as you can dedicate one sunny patch to both herbs.
2. Their Soil Preferences Match Perfectly
Basil and thyme grow well together because they both prefer the exact same type of soil.
A loose, sandy loam that drains quickly is ideal for both herbs, and they both dislike heavy, soggy clay that holds too much water.
The pH level is also a perfect match, with both basil and thyme preferring a neutral to slightly alkaline soil in the range of 6.0 to 8.0.
This means basil and thyme grow well together in the same raised bed or container without you having to adjust the soil conditions for each plant individually.
Just mix in some compost or perlite to improve drainage, and you’ll have both herbs thriving in the same dirt.
3. They Have Complementary Watering Needs
When people ask if basil and thyme grow well together, watering is often the biggest concern because basil likes a bit more moisture than thyme.
However, basil and thyme grow well together because thyme is forgiving of slightly more frequent watering as long as the drainage is sharp.
While basil likes to be kept evenly moist, thyme can tolerate drier conditions, so they kind of balance each other out in a shared bed.
The trick is to water at the base of the basil more heavily and allow the thyme to dry out a bit between waterings.
As long as the soil drains well, basil and thyme grow well together even with these slightly different water appetites.
4. Natural Pest Deterrence Happens Naturally
Another reason basil and thyme grow well together is their combined pest-fighting power.
Basil’s strong aromatic oils are known to repel thrips, mosquitoes, and flies, while thyme’s scent deters cabbage worms and whiteflies.
So when basil and thyme grow well together as companions, they create a natural barrier against common garden pests.
This means you can reduce your need for chemical pesticides, and both herbs stay healthier because they’re protecting each other.
It’s a win-win situation that makes basil and thyme grow well together even more appealing for organic gardeners.
5. They Don’t Compete for Root Space
Basil and thyme grow well together because their root systems occupy different levels of the soil.
Basil puts down a moderately deep, fibrous root system, while thyme stays shallow with a spreading, low-growing habit.
This means basil and thyme grow well together without fighting underground for water or nutrients.
The shallow thyme roots will happily weave around the deeper basil roots without causing any disturbances.
So even in a tight container, basil and thyme grow well together without choking each other out.
How to Plant Basil and Thyme Together
Now that you know basil and thyme grow well together, let’s talk about how to set them up for success in your own garden.
Whether you’re planting in the ground or in pots, a few simple steps will ensure these two herbs flourish side by side.
1. Choose the Right Container Size
If you’re growing in a pot, choose a container that’s at least 12 inches wide and 10 inches deep.
Basil grows tall and bushy, so it needs room to stretch, while thyme will spread out as a low ground cover underneath.
In this setup, basil and thyme grow well together because the thyme fills the lower space while basil takes the upper canopy.
Make sure the pot has plenty of drainage holes because basil and thyme grow well together only in soil that isn’t waterlogged.
2. Plant Thyme at the Front
For garden beds, place the thyme at the front or edge of the planting area, and put basil behind it.
This lets the taller basil receive unobstructed sunlight while thyme gets its share of light along the lower edge.
Since basil and thyme grow well together in terms of sunlight, this simple layout ensures both get adequate exposure.
It also makes harvesting easier because you can snip thyme without reaching through the basil.
3. Water Strategically
Water the basil directly at its base, and let the thyme get whatever moisture runs over.
Alternatively, water the whole pot normally, and just allow the top inch of soil to dry out between waterings.
Basil and thyme grow well together when you avoid overwatering, as thyme will suffer more from wet feet than basil will.
A good rule of thumb is to stick your finger an inch into the soil, and if it’s dry, it’s time to water.
This keeps the balance just right so basil and thyme grow well together without any root rot issues.
4. Feed Lightly and Infrequently
Neither basil nor thyme is a heavy feeder, so skip the heavy fertilizers.
A light application of compost at planting time is all basil and thyme grow well together with.
Too much nitrogen will make basil grow huge, floppy leaves with less flavor, and it will make thyme lose its essential oils.
By keeping feeding minimal, basil and thyme grow well together while keeping their intense aromas and tastes.
Common Mistakes to Avoid When Growing Basil and Thyme Together
Even though basil and thyme grow well together, there are a few pitfalls you’ll want to sidestep to keep both plants happy.
These common errors can stress one herb, even if the other is thriving.
1. Overwatering the Thyme
The most common issue is watering too frequently to please the basil, which drowns the thyme.
If you notice yellowing leaves on the thyme, it’s a sure sign of excess moisture.
Remember that basil and thyme grow well together only when thyme is given a chance to dry out.
Adjust your watering schedule so the soil dries out slightly between sessions, and you’ll be fine.
2. Letting Basil Shade Out Thyme
Basil can get quite tall and bushy, so if you don’t prune it regularly, it may shade the low-growing thyme.
Thyme still needs full sun, even if basil and thyme grow well together in most respects.
Pinch back the basil tips every couple of weeks to keep it compact and allow light to reach the thyme below.
This also encourages bushier basil growth, so it’s a win for both plants.
3. Planting in Dense, Heavy Soil
If you plant basil and thyme in heavy clay or compacted garden soil, the thyme will likely rot over time.
Basil is somewhat tolerant of clay, but thyme absolutely requires sharp drainage.
Always amend your soil with sand or perlite when growing basil and thyme together, and consider a raised bed if your ground is too dense.
With the right soil, basil and thyme grow well together without any drainage drama.
So, Do Basil and Thyme Grow Well Together?
Basil and thyme grow well together, and it’s one of the best companion plantings you can put in your herb garden.
They share sunlight, soil, and pH preferences, they don’t compete for root space, and they even protect each other from pests.
As long as you’re careful about watering and drainage, basil and thyme grow well together in both garden beds and containers.
Hope this post has helped you understand exactly why basil and thyme grow well together and how to care for them side by side.
Now go plant that dynamic duo and enjoy fresh, aromatic herbs all season long.
