Basil and dill grow well together, and they’re actually one of the best herb pairings you can try in your garden.
If you’ve been wondering whether basil and dill grow well together in the same pot, raised bed, or window box, the short answer is a confident yes.
Basil and dill grow well together because they share similar sunlight, water, and soil preferences, which makes companion planting between them incredibly straightforward.
Beyond just surviving side by side, basil and dill grow well together in ways that benefit each other’s flavor, growth rate, and even pest resistance.
In this post, we’ll dig into why basil and dill grow well together, how to plant them successfully, and what to watch out for so both herbs thrive.
Let’s get into the green details.
Why Basil and Dill Grow Well Together
Basil and dill grow well together because they’re both annual herbs that enjoy full sun and consistently moist, well-draining soil.
They don’t compete aggressively for nutrients, and their root systems occupy different depths, which means they aren’t fighting for the same space underground.
The fact that basil and dill grow well together also comes down to their complementary growth habits, with dill reaching upward and basil staying bushier and lower.
1. Shared Sunlight and Temperature Needs
Both basil and dill want at least six to eight hours of direct sunlight every day.
And they both love warm weather, with ideal growing temperatures between 60°F and 80°F.
Since basil and dill grow well together in the same sunny spot, you won’t have to scramble to find separate locations for each herb.
This shared preference means you can plant them side by side in a single container or garden row without one overshadowing the other’s light needs.
2. Matching Water Requirements
When you water one, you can water the other, because basil and dill grow well together with nearly identical moisture needs.
Both prefer soil that stays evenly damp but never soggy or waterlogged.
A good rule is to check the top inch of soil, and if it feels dry, it’s time to water both herbs.
This consistency makes basil and dill grow well together even for beginners who worry about overwatering or underwatering different plants.
3. Beneficial Pest Deterrence
One of the biggest reasons basil and dill grow well together is their combined power against common garden pests.
Dill attracts beneficial insects like ladybugs and parasitic wasps that feast on aphids, mites, and caterpillars.
Basil, on the other hand, repels thrips, flies, and mosquitoes with its strong aromatic oils.
So when basil and dill grow well together, they create a natural defense system where dill calls in the good bugs and basil sends away the bad ones.
4. Flavor Enhancement and Culinary Pairing
Some gardeners swear that basil and dill grow well together because they enhance each other’s essential oil production when planted in close proximity.
While research is still catching up, many home growers report that dill planted near basil becomes more fragrant and flavorful.
And from a culinary standpoint, basil and dill grow well together in the kitchen too, pairing beautifully in salads, sauces, fish dishes, and fresh herbal dressings.
So you’re not just saving garden space, you’re setting up a convenient two-in-one harvest for your cooking.
How to Plant Basil and Dill Together Successfully
Now that you know basil and dill grow well together, let’s talk about how to make that partnership work from seed to harvest.
1. Pick the Right Container or Garden Spot
If you’re growing basil and dill together in a pot, choose a container that’s at least 12 inches wide and 12 inches deep.
That gives dill room to send down its taproot while leaving enough surface area for basil’s shallower roots.
In the ground, basil and dill grow well together with about 12 to 18 inches of spacing between each plant.
This prevents crowding and ensures good airflow, which helps prevent fungal issues like powdery mildew.
2. Plant at the Right Time
Basil is very frost-sensitive, so you should wait until all danger of frost has passed before planting it outdoors.
Dill is a bit more cold-hardy, so you can sow dill seeds a couple weeks earlier than basil.
But if you’re planting them together at the same time, it’s safest to wait until nighttime temperatures stay consistently above 50°F.
When basil and dill grow well together from that point on, they’ll mature at similar rates and give you harvests around the same window.
3. Use Loose, Fertile Soil
Both herbs love loose, loamy soil that’s rich in organic matter.
Mix in some compost or aged manure before planting to give them a strong start.
A slightly acidic to neutral pH between 6.0 and 7.0 is perfect for both.
Because basil and dill grow well together in this kind of soil, you won’t need separate amendments for each herb.
4. Feed Lightly and Regularly
Basil and dill grow well together with light feeding, so don’t overdo the fertilizer.
Too much nitrogen will give you huge, leafy basil but weak, less flavorful dill.
Instead, use a balanced organic fertilizer every four to six weeks during the growing season.
And always water before fertilizing to avoid burning the roots of either herb.
What to Avoid When Growing Basil and Dill Together
Even though basil and dill grow well together, there are a few mistakes that can ruin the partnership.
1. Don’t Let Dill Tower Over Basil
Dill can grow three to five feet tall, while basil usually stays under two feet.
If you plant dill on the south side of basil, the dill’s tall flower stalks can shade out your basil.
To keep basil and dill growing well together, always place dill on the north side of your basil plants.
That way, the basil gets full sun while dill still reaches for the sky without blocking anything.
2. Avoid Overcrowding
It’s tempting to pack basil and dill grow well together into a tiny pot, but overcrowding leads to poor airflow and disease.
If leaves stay wet and cramped, you’ll likely see mildew or rot start to develop.
Thin your seedlings so each plant has enough breathing room, and pinch back basil regularly to keep it bushy.
3. Don’t Let Dill Go to Seed Too Early
Once dill bolts and produces flowers, its leaves become less flavorful, and the plant may start competing more aggressively with basil.
Keep harvesting dill leaves frequently to delay bolting.
If dill does flower, snip the flower heads off right away to keep basil and dill growing well together for a longer harvest period.
4. Watch Out for Fennel’s Reputation
Some people confuse dill with fennel, and while fennel can inhibit other plants, dill is totally fine for basil.
Basil and dill grow well together, but fennel and basil absolutely do not.
So make sure you’re planting true dill, not fennel, if you want that harmonious pairing.
