Use Dill to Repel Cucumber Beetles

One advantage of planting dill alongside cucumbers is its ability to repel cucumber beetles, a common pest for cucumber crops that can cause great damage. Dill contains compounds that emit a strong scent, acting as a natural repellent for cucumber beetles. By interplanting dill, you can naturally deter these beetles without resorting to harmful pesticides.

Proper Spacing is Key

While dill can benefit cucumbers, avoiding planting them too closely together is important. Dill has a tendency to grow tall and bushy and can overshadow cucumber plants if planted nearby.

Aim for at least 18-24 inches between dill and cucumber plants. This spacing allows sufficient room for each plant to receive adequate sunlight while preventing any overshadowing issues.

Corn and Dill Grow Well Together

Corn - small icon

Dill is a natural companion to corn, attracting beneficial insects that prey on common corn pests like aphids or corn earworms.

Dill Attracts Beneficial Insects to Control Corn Pests

Dill companion planting with corn can attract beneficial insects. Parasitic wasps and ladybugs are known to be attracted to dill. These insects are natural predators of common corn pests such as aphids and earworms, which can wreak havoc on a corn crop if left unchecked.

Aphids are small sap-sucking insects that can quickly multiply and damage corn plants. Ladybugs, which feed on aphids, are attracted to dill flowers and can help keep their populations in check.

Earworms are caterpillars that burrow into the ears of corn plants, causing significant damage. Dill attracts parasitic wasps, which are effective predators of these earworms.

Dill Planting Considerations

Avoid overcrowding the corn with dense clusters of dill as this could lead to competition for resources or shading issues for both plants. It’s better to intersperse individual dill plants throughout your corn patch. This allows for better air circulation while still providing enough attraction for beneficial insects.

Onions and Garlic as Dill Companions

Onion - small icon

Onions and garlic are two good companion plant choices for dill that offer numerous benefits.

Non-Competitive Growing Habits

Due to their different growing habits, onions and garlic are ideal companions for dill. While all three plants thrive in full sun and well-drained soil, they occupy different layers within the garden bed. Dill tends to grow tall and lanky, reaching heights of up to 3 feet. Onions and garlic, on the other hand, form bulbs while sending up leafy shoots.

By combining these plants together, you maximize your garden space without competition for resources like sunlight or nutrients. The vertical growth of dill allows it to coexist harmoniously with low-growing onion bulbs or garlic cloves.

Repelling Aphids with Onions and Garlic

A key advantage of growing onions alongside dill is their ability to repel aphids, which love to feast on dill plants, causing damage and stunting their growth. The pungent aroma emitted by onions acts as a natural deterrent, keeping aphids at bay. Garlic also possesses strong scent compounds that have proven effective in repelling these unwanted pests. By interplanting dill with both onions and garlic, you create a powerful barrier against aphid infestations.

Tomatoes and Dill: Friends or Foes?

Tomatoes - small icon

Tomatoes and dill have a complex relationship. While dill helps to repel common tomato pests, it can also hinder tomato growth after it starts to bloom.

Dill as a Tomato Pest-Repellent

One significant benefit of planting dill near tomatoes is its ability to attract predators of tomato hornworms, which can be a big problem for tomato plants. Ladybugs and lacewings are among the beneficial insects attracted to dill, which feast on the hornworms and keep their population in check. By incorporating dill into your tomato patch, you may be able to reduce the damage caused by these pesky pests without resorting to harmful pesticides.

Flowering Dill Can Impede Tomato Growth

The relationship between mature dill and tomatoes can take a negative turn. Once dill reaches maturity and starts to flower, it can hinder the growth of tomato plants by damaging their roots and limiting their future development.

Cherry tomatoes - close-up

The blooming phase of dill marks the point where it becomes less compatible with tomatoes. At this stage, dill competes for essential nutrients in the soil, depriving the tomatoes of what they need to thrive and produce high-quality fruit.

To maintain a beneficial companionship with tomatoes, you can prune dill regularly and prevent it to flower. This practice allows the dill to remain a supportive friend to the tomatoes in their early stages. By being proactive in managing the dill’s growth, gardeners can continue to enjoy the advantages of the early companionship between these two plants.

Bad Garden Companions: Peppers and Carrots

Peppers are Poor Dill Companions

No Peppers - small icon

Peppers plants and dill have incompatible characteristics that can hinder each other’s growth. Peppers possess allelopathic properties, which means they release certain compounds into the soil that inhibit the growth of neighboring plants. Dills happen to be particularly susceptible to these allelopathic effects of peppers.

The allelopathic properties of peppers can stunt the growth of dill and prevent them from reaching their full potential. To ensure successful dill companion planting, it is best to keep both bell peppers and chili peppers away from dill when planning your garden layout.

Carrot Family Vegetables and Dill Are Bad Companions

No Carrots - small icon

Dill is a member of the Apiaceae family, also called the Umbelliferae family, and does not grow well with other members of the family such as carrots and parsnips.

When dill reaches its flowering stage, it can cross-pollinate with other members of the carrot family nearby. Cross-pollination occurs when pollen from one plant is transferred to another plant of the same species. This process can result in undesirable characteristics in both plants involved.

Moreover, growing them close together increases the risk of disease spread between these genetically similar plants. Fungal infections or pests that affect one may easily transfer to the other if they are situated too closely. To ensure healthy growth for both crops and reduce the likelihood of disease transmission, it’s advisable to separate both carrots and parsnips from dill when planning your garden layout.

Bad Herb Companions with Dill

There are many herbs that do not grow well with dill due to their different growing requirements or competition for resources.

Dill’s Moisture Clash: Sage, Rosemary, Thyme & Lavender

Dill prefers consistent moisture and should not be grown near herbs such as sage, rosemary, thyme, and lavender, which prefer drier conditions.

No Sage - small icon

Sage is known for its tolerance to drought-like conditions and should not be planted next to dill. Sage is a perennial herb that prefers drier conditions than dill, which requires far more consistent moisture over time.

No Rosemary - small icon

Rosemary and dill are not recommended as garden companions due to their different growth requirements. Dill prefers more regular moisture than rosemary, which thrives in dry soil with minimal watering.

No Thyme - small icon

Thyme is a very drought-tolerant herb that should not be planted near dill, which has more substantial moisture requirements. With its preference for drier conditions, thyme is not a suitable companion plant for dill.

No Lavender - small icon

Lavender thrives in soil that is relatively dry, unlike dill which has a preference for regular moisture levels. Planting lavender alongside dill may result in overwatering the latter or underwatering the former, resulting in poor health for one or the other plant.

Cilantro and Dill: Cross-Pollination

No Cilantro - small icon

Cilantro and dill are poor garden companions due to the risk of cross-pollination, as they are both members of the Apiaceae family. Cross-pollination can result in undesirable hybridization, leading to plants with compromised flavor or other undesirable characteristics. For this reason, it is not recommended to plant cilantro and dill in proximity to one another.

Caraway and Dill: Resource Rivalry

No Caraway - small icon

Caraway is another herb that should be kept separate from dill when planning your herb garden. Both caraway and dill compete for vital resources such as water and nutrients necessary for their growth. When planted together, this resource rivalry can lead to stunted growth for both herbs.


In summary, companion planting with dill can significantly enhance your garden by improving pest control and attracting beneficial insects. Spacing and understanding growing conditions are important for taking advantage of these benefits..

However, dill doesn’t pair well with all plants. Tomatoes can benefit from dill’s pest-repelling properties, but once dill flowers, it can hamper their growth. Peppers, carrots, and drought-tolerant herbs should be avoided due to moisture issues, cross-pollination, and resource competition.

Understanding and applying companion planting principles is key to creating a thriving garden. Each garden is unique, so careful observation and adjustment are paramount to success. Happy gardening!
