Companion Planting In Your Herb Garden

By Mary H. Dyer, Master Naturalist and Master Gardener

We all know the benefits of vegetable companion planting, but what about growing herbs as companion plants? Creating a companion herb garden is no different and allows you to take advantage of their beneficial relationships with other plants.

Reasons for Companion Planting an Herb Garden

Companion planting with herbs offers numerous benefits. For example, companion planting with herbs can discourage pests, which often occurs when you plant companion herbs that exude an aroma that pests find unpleasant. On the other hand, some herbs that grow well together can actually attract beneficial insects or draw unwanted pests away from more susceptible herbs.

Some herbs can even increase the essential oils in companion herbs. However, some herbs that don’t grow good together can draw nutrients and moisture from their companion plants. When choosing companion plants for your herb garden, consider these factors:


Heavy feeders planted next to each other will compete for nutrients in the soil.
Strong smelling/tasting plants planted next to one another may change the flavors and scents of other herbs or vegetables.

Note: Keep in mind that some herbs just don’t grow good together. For example, fennel doesn’t get along well with most other plants and is best planted in an area all by itself, mostly because of the strong aroma. However, from its solitary location, fennel repels fleas and aphids and attracts beneficial pollinators.
