Dill Companion Planting
(tips on growing dill in your garden)
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 herb companion planting.
Dill Companion Plants.
Planting dill nearby will help help asparagus, the Brassicas (broccoli, brussels sprouts, cabbage, cauliflower and kholrabi), chervil, corn, cucumber, lettuce and onion. Conversely, planting beans near dill will be beneficial to the growth of your dill plants.
Growing angelica, cabbage, caraway, carrots, chili and bell peppers, eggplant, fennel or potatoes near dill as a bad idea because all of them are poor companion plants for dill.
Dill, Carrots & Cross Fertilization.
Dill and carrots are both in the Umbelliferae family. If dill is allowed to flower, it can cross polinate with carrots which is why the two should not be planted together. Dill can also cross-polinate 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
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.
