Rosemary thrives alongside sun-loving companions like cabbage, beans, carrots, and peppers. It pairs beautifully with Mediterranean herbs like oregano and sage. Avoid pairing rosemary with fennel, basil, or water-loving cucumbers to prevent competition and growth issues.
Rosemary is a perennial herb or shrub with fragrant, evergreen, needle-like leaves and white, pink, lavender, or blue flowers, native to the Mediterranean region. It belongs to the mint family, Lamiaceae, along with basil, mint, sage, oregano, and thyme.
Rosemary is widely used as a culinary herb and in traditional medicine. It is also grown as an ornamental plant in gardens and is prized for its distinctive fragrance and essential oil, widely used in aromatherapy. Discover the key benefits of growing Rosemary in your garden.
Companion planting is an organic method of preventing or protecting plants from pests and diseases, attracting the right types of insects for pollination, enhancing nutrient uptake, and increasing crop production simply by growing specific plants near each other. In essence, companion planting helps bring a balanced ecosystem to your landscape, allowing nature to do its job.
Some plants can emit scents that either repel insects, attract them, or confuse insects or disease organisms in search of their favorite host plants. They make insects less likely to land on your garden vegetables.
Rosemary naturally repels cabbage loopers, bean beetles, carrot flies, mosquitoes, slugs, and snails.
Some plants help attract beneficial insects, such as ladybugs, bees, and butterflies, that pollinate and help control harmful bugs. Beneficial insects feed on common garden pests like aphids and caterpillars.
Rosemary flowers are a magnet for pollinators, drawing in bees, honeybees, bumblebees, butterflies, and even hummingbirds.
Tall sun-loving plants offer shade to smaller shade-loving plants. This results in better products and can also potentially provide pest control. A good example is The Three Sisters Garden. Practiced by Native Americans thousands of years ago, this garden includes corn, beans, and squash. The tall corn provides shade for the lower squash but also stops the squash vine borer beetle.
Some plants can provide windbreaks and prevent soil erosion. Strong winds can damage gardens by removing mulch, topsoil, and eroding beds and hillsides. Rain can also cause severe damage by beating down young seedlings. By carefully selecting the right ground cover, you can help prevent soil erosion.
Some companion plants can physically support each other, reducing the need for staking. The example of planting corn, beans, and squash together applies here again. Corn provides tall stalks for the beans to climb so that they are not out-competed by sprawling squash vines.
Interplanting different crops greatly maximizes space and improves productivity in small gardens.
Some plants can subtly enhance the flavor of other plants. Most herbs have been found to enhance the flavor of fruits and vegetables grown nearby, and basil grown beside tomatoes is an excellent example. Similarly, chamomile has an aromatic scent that is believed to improve the growth and flavor of cabbage, cucumbers, and onions when grown beside them.
Some crops help fix nitrogen from the atmosphere and reduce fertilizer needs. Similarly, planting plants with different root structures together can aerate the soil and allow plants to pull nutrients from different parts of the soil. Not only can companion planting help your plants to grow better, but it also makes the vegetable garden more attractive thanks to the addition of colorful flowers that help or hinder nearby vegetables. Companion planting combines beauty and purpose to create an enjoyable, healthy environment.
Examples: Broccoli, cabbage, cauliflower, kale, Brussels sprouts.
Why: Rosemary’s strong fragrance masks the scent of brassicas, helping to deter cabbage moths and cabbage loopers. This natural protection reduces pest damage and promotes healthier crops.
Why: Rosemary’s aromatic oils help ward off Mexican bean beetles, protecting beans from leaf damage. They also have compatible growth habits and do not compete for soil nutrients.
Why: Rosemary repels carrot flies and other root pests. Its scent confuses harmful insects, leading to stronger, healthier carrots and parsnips and better yields.
Why: Rosemary’s strong scent helps repel common pepper pests such as aphids, spider mites, and other insects. Scientific experiments and gardening sources confirm that rosemary significantly reduces aphid numbers and reproduction on pepper plants, thanks to its volatile organic compounds (VOCs).
Why: Sage and rosemary enjoy similar conditions—full sun and well-drained soil—and support each other’s growth. Sage is one of the few herbs that grows harmoniously alongside rosemary.
Why: Lavender, marjoram, oregano, and thyme are Mediterranean herbs that love the same dry, sunny conditions as rosemary. Together, they form a resilient, aromatic herb bed that attracts pollinators and helps conserve soil moisture.
Examples: Onions, garlic, and chives.
Why: They mutually enhance pest resistance, do not compete for resources, and thrive under similar growing conditions, making them ideal partners in both herb and vegetable gardens
Why: Rosemary’s pest-repelling scent protects strawberries from slugs and insects. Its deeper roots also help improve soil structure for shallow-rooted strawberries.
Why: Marigolds, alyssum, borage, and zinnia bring in beneficial insects and pollinators, while rosemary drives pests away. Together, they create a colorful, balanced garden ecosystem.
