Basil and dill are companion plants, and pairing them together in your garden can create a wonderfully harmonious and mutually beneficial relationship.
If you’ve been wondering whether basil and dill companion plant well together, the answer is a resounding yes, as they share similar growing requirements and offer each other protective benefits that can boost your overall harvest.
You can absolutely grow basil and dill as companion plants because they don’t compete aggressively for nutrients, and their distinct aromas actually work to confuse and repel a variety of common garden pests that might otherwise wreak havoc on your herbs.
In this post, we’ll explore why basil and dill are such great companion plants, the specific ways they support each other, and how to successfully grow them side by side in your garden beds or containers.
Let’s dig into the wonderful world of companion planting with basil and dill.
Why Basil and Dill Are Great Companion Plants
The reason basil and dill are considered excellent companion plants starts with their complementary growth habits and shared environmental preferences.
Both basil and dill thrive in full sun, which means you won’t have to worry about one overshadowing the other or struggling due to light deprivation.
Basil and dill companion planting works because they both prefer well-drained soil with moderate moisture, so you can water them on the same schedule without stressing either plant.
Let’s break down the specific reasons these two herbs make fantastic garden partners.
1. Pest Repellent Properties
One of the biggest benefits of growing basil and dill as companion plants is their powerful ability to repel pests that commonly attack garden herbs.
Basil emits a strong, pungent aroma that naturally deters aphids, spider mites, and tomato hornworms from your garden.
Dill, on the other hand, is known to confuse cabbage worms and carrot flies, making it a valuable ally when planted near brassicas or root vegetables.
When you combine basil and dill companion plants, the mixed scents create an aromatic barrier that many insects find overwhelming and unappealing.
This natural pest control is a major reason why so many gardeners swear by planting basil and dill together.
2. Attracting Beneficial Insects
Not only do basil and dill repel harmful insects, but they also attract a host of beneficial predators that keep your garden ecosystem balanced.
Dill produces delicate umbels of yellow flowers that are incredibly attractive to ladybugs, lacewings, and parasitic wasps, all of which feast on common garden pests.
Basil flowers, while less showy, also draw in bees and other pollinators that help improve the overall health and productivity of your entire garden.
When basil and dill are companion plants, they create a welcoming habitat for these natural helpers, ensuring that pest populations stay under control without any harsh chemicals.
This makes basil and dill companion planting a smart, eco-friendly strategy for any home gardener.
3. Space Efficiency and Growth Habits
Basil and dill have very different physical structures, which means they can grow together without crowding each other out.
Basil tends to grow as a bushy, low to medium-height plant, spreading outwards and filling in the lower layers of the garden.
Dill, in contrast, grows tall and airy, reaching heights of two to four feet, especially when it bolts to flower in the heat of summer.
These complementary habits mean basil and dill are companion plants that utilize vertical space efficiently, allowing you to maximize your yield in a smaller area.
The tall dill provides a bit of dappled shade for the basil during the hottest part of the day, which can actually help prevent basil from bolting too quickly.
And the basil acts as a living mulch of sorts, shading the soil and helping to retain moisture for the shallow-rooted dill.
How to Successfully Grow Basil and Dill Together
Now that you know why basil and dill are such great companion plants, let’s talk about how to set them up for success in your own garden.
While they get along famously, there are a few key considerations to keep in mind to ensure both herbs thrive as companion plants.
1. Spacing and Placement
When planting basil and dill as companion plants, proper spacing is crucial to prevent any potential issues with airflow or competition.
Give your basil plants about 12 to 18 inches of space between them, and allow them to form their bushy shape without being cramped.
For dill, space the plants about 12 to 24 inches apart, depending on the variety, and make sure they are placed behind or to the north of the basil so they don’t shade the shorter herbs excessively.
A good rule of thumb is to interplant them in staggered rows, so the dill reaches for the sky while the basil fills in the gaps below.
This arrangement ensures that basil and dill companion plants coexist without either one sacrificing its growth.
2. Soil and Watering Needs
Basil and dill both appreciate rich, fertile soil that drains well, so amending your bed with compost before planting is a fantastic idea.
These companion plants prefer a slightly acidic to neutral pH, somewhere between 6.0 and 7.0, which is the sweet spot for most herb gardens.
When it comes to watering, basil is a bit thirstier than dill, so you’ll need to find a balance that keeps the soil consistently moist but never waterlogged.
Mulching around your basil and dill companion plants can help retain soil moisture and regulate temperature, reducing the stress on both herbs.
Just be careful not to overwater the dill, as it’s more drought-tolerant and can develop root rot in soggy conditions.
3. Harvesting for Continuous Growth
To keep your basil and dill companion plants productive all season long, you need to harvest them regularly and correctly.
For basil, pinch off the top sets of leaves as soon as the plant has six to eight true leaves, which encourages bushier growth and delays flowering.
For dill, you can start harvesting the feathery leaves once the plant is about 6 inches tall, taking the outer leaves first to promote new growth from the center.
If you want to collect dill seeds, let a few plants flower and go to seed, but be aware that dill will stop producing fresh leaves once it bolts.
When you harvest basil and dill as companion plants, you’re not just gathering food, you’re also pruning them to maintain their ideal shape and vigor.
This regular harvesting ensures your basil and dill companion planting setup continues to flourish well into the fall.
Common Mistakes to Avoid with Basil and Dill
Even though basil and dill are fantastic companion plants, there are a few pitfalls you’ll want to avoid to keep them healthy and happy.
Let’s look at some of the most common errors gardeners make with this particular pairing.
1. Planting Too Close Together
While basil and dill are companion plants, that doesn’t mean you should cram them together tightly.
If dill is planted too close to basil, it can shade the basil too much, leading to leggy, weak growth and fewer leaves.
On the flip side, if basil is too close to the dill, it can trap moisture at the base of the dill, increasing the risk of fungal diseases.
Respect the spacing recommendations, and your basil and dill companion plants will reward you with robust, flavorful harvests.
2. Letting Dill Go to Seed Too Early
Dill is an annual that bolts quickly in hot weather, and once it flowers, the leaves lose much of their flavor and become bitter.
If you let all your dill go to seed, you’ll sacrifice the leaf harvest that makes it such a valuable companion plant.
To prevent this, sow dill seeds every two to three weeks in succession, so you always have fresh young plants coming along.
This succession planting strategy ensures that your basil and dill companion planting setup includes a steady supply of tender dill leaves throughout the season.
3. Overfeeding with Fertilizer
Basil and dill are not heavy feeders, and over-fertilizing can actually harm them as companion plants.
Too much nitrogen will cause basil to grow lush, soft leaves that are more susceptible to pests and disease, while diluting the essential oils that give it its aroma.
For dill, excessive nitrogen can lead to tall, floppy plants with weak stems that may topple over.
A light application of compost at planting time and perhaps a single mid-season feeding with a balanced organic fertilizer is more than enough.
Remember, the goal with basil and dill companion plants is to keep them healthy and flavorful, not to push them into explosive growth.
So, Are Basil and Dill Companion Plants?
Basil and dill are companion plants, and they make an outstanding pair for any vegetable or herb garden.

When you grow basil and dill as companion plants, you create a healthier, more productive, and more resilient garden with minimal extra effort.
Just remember to space them correctly, water them thoughtfully, and harvest them regularly to keep the partnership thriving.
