Home > Latest > Gardening > Oregano Companion Plants

Companion planting is a gardening technique where certain plants are grown together to benefit each other in various ways. One plant that can thrive alongside many others is oregano. Oregano, a perennial herb known for its aromatic leaves and culinary uses, not only adds flavor to dishes but also has several beneficial properties for neighboring plants. In this article, we will explore some of the best companion plants to grow alongside oregano in your garden.


Oregano and tomatoes are classic examples of companion planting. Tomatoes and oregano have complementary growth habits and can mutually enhance each other’s flavor. Oregano can help repel pests that commonly affect tomatoes, such as aphids and spider mites. Additionally, the strong scent of oregano can confuse and deter harmful insects. Plant oregano near tomatoes to create a healthy and pest-resistant environment for your tomato plants.


Basil and oregano make excellent companions in the garden. Both herbs belong to the mint family and have similar growth requirements. They thrive in similar soil conditions and sunlight exposure. Planting basil alongside oregano can help improve the overall health and flavor of both herbs. Additionally, basil’s strong aroma can deter pests that might damage oregano, such as aphids and whiteflies. This pairing not only benefits the plants but also provides gardeners with an abundant supply of flavorful herbs for culinary creations.


Marjoram is a close relative of oregano and shares many of its characteristics. These two herbs make great companions in the garden due to their compatibility in growth requirements. Planting marjoram alongside oregano can create a visually appealing herb bed and provide an abundance of aromatic leaves for culinary purposes. Marjoram also attracts beneficial insects like bees and butterflies, which can help with pollination in the garden.


Oregano can be an excellent companion for various types of beans, including bush beans and pole beans. The strong scent of oregano acts as a natural repellent for pests that commonly affect beans, such as Mexican bean beetles and aphids. Additionally, oregano’s compact growth can provide shade and reduce weed growth around the bean plants. The combination of oregano and beans can create a symbiotic relationship, promoting healthy growth and reducing the need for chemical pesticides.

Cabbage Family Plants

Members of the cabbage family, including cabbage, broccoli, cauliflower, kale, and Brussels sprouts, can benefit from having oregano as a companion plant. Oregano’s strong aroma can deter pests like cabbage moths and cabbage loopers, which are common culprits that damage cabbage family plants. Additionally, oregano’s shallow root system does not compete heavily with the deep-rooted cabbage plants, making them compatible for growing together.


Oregano can be a valuable companion plant for peppers. Similar to tomatoes, peppers can benefit from oregano’s pest-repellent properties. Oregano’s strong fragrance can confuse and deter pests that commonly affect peppers, such as aphids and pepper maggots. Additionally, oregano’s low-growing habit can provide shade and help retain soil moisture around pepper plants. Planting oregano alongside peppers can promote healthier plants and reduce the need for chemical pest control methods.

Lettuce and Salad Greens

Oregano can be grown alongside lettuce and other salad greens to enhance their growth and flavor. While oregano’s taller growth habit may provide some shade to the lower-growing lettuce plants, it does not hinder their growth significantly. The pungent aroma of oregano can help repel pests that commonly target lettuce, such as slugs and snails. Additionally, oregano’s presence can add a unique and savory twist to salads and other culinary creations.


In conclusion, oregano is a versatile herb that can serve as a valuable companion plant in your garden. Its aromatic leaves, pest-repellent properties, and compatibility with various plant species make it a beneficial addition to many gardens. By strategically planting oregano alongside tomatoes, basil, marjoram, beans, cabbage family plants, peppers, and lettuce, you can create a harmonious and thriving garden ecosystem. Take advantage of the benefits of companion planting with oregano to promote healthier plants, deter pests, and enhance the flavors of your culinary creations. Happy gardening!
