Dill is one of our favorite flavors. We often use it in egg and potato salad. There’s nothing better than tender, fresh dill leaves to really perk up a dish.

Dill is an interesting plant because it makes a great companion for a number of vegetables and other herbs. But, there are a few exceptions and contradictions regarding our dill companion planting research. Before gardening with dill, you should review this companion planting guide and our guides on growing dill and companion planting with herbs.

Dill Companion Planting

Companion planting dill will help help asparagus, the Brassicas (broccoli, brussels sprouts, cabbage, cauliflower and kohlrabi), chervil, corn, cucumber, lettuce and onion. Conversely, planting beans near dill will be beneficial to the growth of your dill plants. One source identified lettuce as the best dill companion plant.

Companion planting dill with Growing angelica, cabbage, caraway, carrots, chili and bell peppers, eggplant, fennel, lavender or potatoes is not recommended as they are all poor companions for dill.

Dill, Carrots & Cross Fertilization.

Dill and carrots are both in the Umbelliferae family. If dill is allowed to flower, it can cross pollinate with carrots which is why the two should not be planted together. Dill can also cross-pollinate fennel but is one of the few good companion plants for fennel.

Companion Planting Dill & Cauliflower

Our sources were contradictory about planting cauliflower with dill. It is probably not worth the risk to plant them together.

Companion Planting Tomatoes & Dill

Obtaining the benefits of companion planting dill with tomatoes requires a bit of vigilance. The growth and health of tomatoes will improve from being planted near young dill. However, once the dill matures it will stunt the growth of your tomatoes and should be moved. Dill also attracts tomato horn worms which will make it easier for the pests to find your tomato plants if the dill plants are left to mature.

Dill & Insects.

Dill attracts a number of beneficial insects to your garden. Those insects include honeybees, hoverflies, Ichneumonid wasps and other wasps. Swallowtail butterfly caterpillars particularly enjoy dill.

Dill plants are said to be an effective natural insect repellent against aphids, cabbage looper, spider mites and squash bugs.
