Basil and dill can grow together in the same garden bed or container with a little planning.
If you’ve been wondering whether basil and dill grow together well, the short answer is yes, they make surprisingly good companions.
You can grow basil and dill together because they share similar sunlight and watering needs.
In this post, we’ll explore why basil and dill grow together so nicely, the best conditions for both herbs, and a few tips to keep them thriving side by side.
Let’s dig into the details of growing basil and dill together.
Why Basil and Dill Grow Together as Companions
Basil and dill grow together because they benefit each other in the garden.
Dill attracts beneficial insects like ladybugs and lacewings, which help keep pests away from your basil.
Basil, on the other hand, can help repel some common garden pests that might bother dill.
This mutual protection is a classic example of companion planting.
When you grow basil and dill together, you also maximize your garden space.
Both herbs are compact enough to share a bed or a large container without crowding each other out.
Let’s look at the specific reasons basil and dill grow together so harmoniously.
1. Similar Sunlight Requirements
Basil and dill grow together best when they get full sun, meaning at least six to eight hours of direct light daily.
Both herbs thrive in warm, bright conditions, so placing them in the same sunny spot works perfectly.
If you have a south-facing window or a sunny patio, you can easily grow basil and dill together there.
Just make sure neither plant is shaded by the other as they grow.
Taller dill might cast shade on shorter basil, so plant them with enough space between them.
2. Compatible Watering Needs
When you grow basil and dill together, you don’t have to worry about conflicting watering schedules.
Both herbs prefer consistently moist but well-draining soil.
They dislike sitting in soggy ground, so a good potting mix with drainage holes is essential.
Watering your basil and dill together about once a day during hot weather keeps both happy.
In cooler months, check the soil with your finger and water only when the top inch feels dry.
This shared preference makes basil and dill grow together without much fuss.
3. Mutual Pest Deterrence
One of the best reasons basil and dill grow together is their natural pest-fighting abilities.
Dill’s strong scent confuses pests like aphids and spider mites that might attack basil.
Basil’s aromatic oils repel mosquitoes, flies, and even some beetles that could damage dill.
Planting them together creates a mini fortress against common garden invaders.
This means fewer chemicals and less effort on your part.
4. They Attract Pollinators
Basil and dill grow together to create a pollinator-friendly zone in your garden.
Once dill flowers, it draws bees and butterflies like crazy.
Basil blossoms also attract bees, even though you usually pinch them off for better leaf growth.
If you let a few plants flower, your garden will buzz with activity.
More pollinators mean better yields for your vegetables and herbs nearby.
Best Practices for Growing Basil and Dill Together
Now that you know basil and dill grow together, let’s talk about how to do it right.
A few simple practices ensure both herbs flourish side by side.
1. Give Them Enough Space
Even though basil and dill grow together fine, they still need breathing room.
Dill can reach two to three feet tall, while basil usually stays around one to two feet.
Space your plants about 12 to 18 inches apart.
This prevents dill’s feathery leaves from smothering basil’s bushy growth.
If you’re using a container, choose one that’s at least 12 inches deep and wide.
2. Plant Them at the Right Time
You can start basil and dill together after the last frost date in your area.
Both herbs are tender annuals that don’t handle cold well.
Plant seeds or seedlings in late spring when the soil has warmed up.
You can also sow dill a bit earlier than basil if you want a staggered harvest.
But for the easiest time, plant them at the same time and let them grow together from the start.
3. Feed Them Lightly
Basil and dill grow together best with light, occasional feeding.
Too much fertilizer makes dill grow spindly and reduces basil’s essential oils and flavor.
Instead, mix some compost into the soil at planting time.
Then, feed with a diluted liquid fertilizer once a month during the growing season.
That’s plenty of nutrition for basil and dill to grow together happily.
4. Harvest Regularly
Frequent harvesting keeps basil and dill growing together productive and bushy.
Pinch basil leaves from the top to encourage new growth and prevent flowering.
Cut dill leaves from the outer stems, leaving the inner leaves to keep growing.
If dill bolts and flowers, that’s okay, you can still use the seeds.
But regular trimming keeps both herbs tender and flavorful.
Common Mistakes When Growing Basil and Dill Together
Even though basil and dill grow together easily, a few errors can cause problems.
Avoiding these mistakes keeps your herbs healthy and strong.
1. Overwatering
Too much water is the biggest killer of basil and dill growing together.
Both herbs develop root rot if their roots stay constantly wet.
Make sure your container has drainage holes and your soil isn’t heavy clay.
If leaves start yellowing, that’s a sure sign you’re overwatering.
Let the topsoil dry out slightly between waterings.
2. Planting Too Close Together
Crowded conditions cause poor air circulation and invite fungal diseases.
When basil and dill grow together too tightly, they compete for nutrients and light.
This leads to weak, leggy growth and less flavor.
Always follow the spacing guidelines, even in containers.
3. Letting Dill Take Over
Dill can grow tall and wide if left unchecked.
If it overshadows your basil, the basil won’t get enough sun.
Prune dill regularly to keep it compact.
You can also plant dill behind basil so it naturally towers without blocking light.
So, Can Basil and Dill Grow Together?
Basil and dill can grow together in your garden or containers with great success.
They share similar sunlight, water, and soil needs, making them low-maintenance companions.
Plus, they help each other by repelling pests and attracting beneficial insects.
You can grow basil and dill together as long as you give them space and harvest regularly.
Now you know exactly how basil and dill grow together, so go ahead and plant them side by side this season.
