10 Best Rosemary Companion Plants To Grow Together

Integrating rosemary into your garden is more than just introducing an herb; it is about building a symbiotic environment where plants help each other develop. Rosemary companion plants are picking plants that benefit from their presence, whether by repelling pests, improving flavor, or promoting growth. This post discusses the ideal rosemary partners to keep your garden harmonious and fruitful.

What Is Companion Planting?

Companion planting, an age-old agricultural practice, combines the symbiotic interactions of many plant species to promote growth, discourage pests, and improve flavor. 

This concept, heavily steeped in permaculture ideas, goes beyond folklore to represent a comprehensive approach to gardening and farming.

Among the many herbs, rosemary stands out as the ultimate companion plant, valued for its olfactory appeal and its sturdy capacity to cohabit and thrive with other plants.

What Are The Benefits of Rosemary Companion Planting?

Companion planting with rosemary brings a plethora of benefits to the garden, enhancing both the health and yield of various plants. Rosemary is a culinary delight and a formidable ally in the natural garden ecosystem. Let’s explore the multifaceted advantages of incorporating rosemary into your companion planting strategy:

  • Pest Repellent: Rosemary’s strong scent is a natural deterrent for many garden pests, including cabbage moths, bean beetles, and carrot flies. Its aromatic oils are especially effective in repelling mosquitoes and other insects, making it an ideal companion for various vegetable and herb plants.
  • Pollinator Attraction: While it repels unwanted pests, rosemary’s blue, violet, white, or pink flowers attract bees, butterflies, and other beneficial pollinators. This is crucial for pollinating many other plants in your garden, enhancing their productivity and health.
  • Soil Improvement: Rosemary thrives in well-drained, slightly alkaline soil. Its deep root system can help break up heavy soils, improving soil structure and nutrient availability for neighboring plants with shallow roots.
  • Companion Support: Certain plants benefit significantly when grown near rosemary. For example, rosemary can enhance the flavor and growth of vegetables and herbs such as beans, cabbage, and sage by creating a more favorable microenvironment.
  • Disease Prevention: The aromatic oils in rosemary also have antifungal and antibacterial properties, which can help protect companion plants from various diseases. This is particularly beneficial in humid climates where fungal diseases thrive.
  • Spatial Efficiency: Rosemary is a hardy, drought-resistant plant that can thrive in conditions where other plants might not. Its ability to grow in less-than-ideal conditions makes it an excellent plant for maximizing space and diversifying garden plantings.

By leveraging the benefits of rosemary companion planting, gardeners can create a more resilient, aromatic, and productive garden. This holistic approach enhances the garden’s aesthetic appeal and promotes a healthier, more sustainable gardening practice.

3 Worst Rosemary Companion Plants

While companion planting with rosemary can offer numerous benefits, it’s equally important to recognize which plants might not fare well when placed close to this aromatic herb. Certain plants can suffer from being near rosemary due to differences in growth requirements, competition for resources, or adverse chemical interactions. 

Here, we discuss three plants considered less-than-ideal companions for rosemary: mint, basil, and pumpkins.


Mint and rosemary are not compatible as companion plants for several reasons. First, mint is an aggressive spreader that tends to take over garden spaces, which can lead to competition with rosemary for soil nutrients and water. 

Additionally, mint prefers more moisture in the soil than rosemary, which thrives in well-drained, drier conditions. This fundamental difference in water needs can make it challenging to care for both plants close, potentially stressing or harming the rosemary.


At first glance, basil and rosemary might seem like good companions due to their everyday use in culinary dishes. However, basil has different watering needs compared to rosemary. Basil requires consistently moist soil to thrive, whereas rosemary prefers conditions on the dryer side. 

This discrepancy can lead to overwatering for rosemary or underwatering for basil when planted too closely, hindering the growth and health of both herbs.

Pumpkins, being large, sprawling plants, require a lot of space to grow, with extensive vines that can cover a lot of ground. When planted near rosemary, pumpkins can easily overshadow the herb, limiting its access to sunlight.

Moreover, pumpkins have significant water and nutrient requirements, which can conflict with rosemary’s preference for less fertile, well-drained soil. The disparity in their growing conditions makes it difficult to meet the needs of both plants when they are grown together, potentially compromising their health and yield.

FAQ’s About Planting Rosemary

What not to plant next to rosemary?

Avoid planting rosemary next to plants that require high moisture levels in the soil, such as mint, basil, and cucumbers. These plants have significantly different watering needs than rosemary, which prefers dry conditions. 

Additionally, avoid planting rosemary near large, sprawling plants like pumpkins, which can overshadow it and compete for nutrients and water.

Where is the best place to plant rosemary?

The best place to plant rosemary is in a location that receives full sunlight for most of the day, as rosemary thrives in bright light. It should be planted in well-draining soil to prevent root rot. 

Rosemary does well in both ground and containers, making it versatile for garden placement. If you live in a cooler climate, consider planting rosemary in a pot that can be brought indoors during harsh winters, as it is not frost-tolerant.

Can I plant rosemary in my vegetable garden?

Yes, you can plant rosemary in your vegetable garden. It makes an excellent companion plant for many vegetables by repelling pests and attracting beneficial insects. 

Plants that benefit from being near rosemary include beans, carrots, and cauliflower. Just ensure that its placement doesn’t overshadow smaller plants or impede the growth of those with different water and soil requirements.

Does rosemary like direct sunlight?

Yes, rosemary loves direct sunlight. It thrives best when it receives at least 6 to 8 hours of direct sunlight daily. 

Adequate sunlight is crucial for rosemary to develop its robust flavor and aromatic oils. If you’re growing rosemary indoors, place it near a south-facing window to ensure it gets enough light.

Final Thoughts

Rosemary is a wonderfully versatile herb that not only adds flavor to dishes but also brings numerous benefits to the garden. Its ability to repel pests and attract pollinators makes it a valuable companion plant. 

However, success with rosemary also requires understanding its needs and which plants make good neighbors. By providing full sunlight, well-draining soil, and careful consideration of companion planting, you can enjoy the lush growth and aromatic presence of rosemary in your garden. 

Remember, gardening is a learning process, and each plant adds to your experience and knowledge. Happy gardening!
