Companion planting dill and corn make a fantastic option. The tall stalks of corn provide shade to the delicate dill plants, protecting them from excessive heat and preventing them from bolting. 

In return, dill attracts beneficial insects that help pollinate the corn plants. This mutually beneficial relationship between corn and dill makes them ideal companions in the garden.

Dill and cucumber are not only a dynamic duo in the kitchen but also in the garden. Planting dill near cucumbers can help improve the flavor and growth of cucumbers. 

Moreover, dill attracts insects that prey on common cucumber pests, such as aphids and cucumber beetles. This natural pest control makes cucumber an excellent companion plant for dill.

Companion planting dill and onions can result in a beneficial relationship. Onions can help deter pests that may be attracted to dill, such as aphids and spider mites. On the other hand, dill can attract beneficial insects that prey on onion pests, like onion flies.

Worst Dill Companion Plants

Here are five companion plants for dill that should be avoided:

tomatoes don't make good neighbors with dill


Companion planting dill and tomatoes are not ideal. Tomatoes release chemicals that can inhibit the growth of dill and other herbs.

Additionally, both plants require different growing conditions, with tomatoes preferring warmer temperatures and dill thriving in cooler environments. 

It’s best to keep these two plants separate in your garden.

carrots growing in the vegetable garden,  are not great companion planting dill


Due to their different growth requirements, carrots and dill are not ideal planted together. Carrots prefer loose soil without competition from other plants, while dill grows best in richer soil with companions that provide shade and support.

Planting dill near carrots can hinder the growth and development of both plants, so it’s best to avoid this pairing.

cilantro plant growing in the vegetable garden, companion plants


Cilantro and dill are herbs with strong flavors but do not make good companions in the garden. These herbs can cross-pollinate, resulting in undesirable flavors and textures.

It’s best to plant cilantro and dill in separate areas to maintain the distinct qualities of each herb.

Peppers + Other Nightshades

Peppers and other nightshade plants, such as eggplants and potatoes, should not be planted near dill. Dill can attract pests such as aphids and spider mites that harm nightshade plants.

Additionally, the strong aroma of dill can interfere with the flavors of peppers and other nightshades. Keep these plants at a distance to ensure their optimal growth.

lavender, garden's growth with dill


While lavender is a beautiful flowering plant, it is not a suitable companion plant for dill. Lavender requires well-drained soil, while dill prefers slightly moist conditions.

Moreover, lavender can overshadow delicate dill plants, hindering its growth. Planting lavender and dill in separate areas is best to allow both plants to thrive.

FAQs for Dill Companion Planting

Are parsley and dill companion plants?

Despite sharing similar light, soil, and water requirements, dill and parsley do not make suitable companion plants. This is because both belong to the carrot family (like carrots and fennel), they will attract similar pests that damage these other crops.

Are peas and dill companion plants?

Peas and dill are not considered ideal companion plants. Peas have different growth requirements and can overshadow delicate dill plants. It’s best to avoid planting them together to ensure the optimal growth of both plants.

Is dill hard to grow?

No! Dill is one of the easiest herbs to grow and keep alive, with fast growth rates, flexible growing needs, and self-seeding properties. Just be careful that it doesn’t overtake your growing space.

Can you plant dill near tomatoes?

Dill is an interesting exception among herbs (along with basil) that can be grown alongside tomatoes. When young, dill plants actually benefit tomatoes by repelling aphids; those pesky little pests that tend to wreak havoc in gardens.

However, as dill matures and starts producing seeds, it can hinder the growth of tomato plants if too many dill plants start popping up and they begin to take over and become too established.

Final Thoughts on Dill Companion Planting

Dill companion planting can significantly benefit your garden by enhancing growth, deterring pests, and improving flavor. Consider shade, soil conditions, and pest resistance when choosing dill companion plants. You can create a harmonious and thriving garden ecosystem by strategically pairing dill with compatible plants.
