The 8 Best Companion Plants for Rosemary (And the Ones That Will Ruin It)

If you’re a fan of growing rosemary, you already know it’s one of the most versatile and rewarding herbs to have in your garden. But did you know that pairing it with the right plants can take your gardening game to the next level?

Whether you’re aiming for better growth, pest control, or a thriving herb garden, companion planting can make all the difference.

On the flip side, choosing the wrong neighbors can leave your rosemary struggling—or worse, failing altogether.

Its subtle aroma complements rosemary without overpowering it, making them perfect companions.

This combination not only benefits growth but also adds an appealing aesthetic to your garden, with contrasting textures and complementary hues.

Their companionship doesn’t just enhance growth but also enriches the garden’s aroma, as oregano’s fragrance mingles with that of rosemary. Oregano also attracts beneficial insects, contributing to a balanced ecosystem.

Together, they form a resilient duo that supports each other’s growth, making them a staple in any herb garden.

Carrots and rosemary might seem an unlikely pair, but they can benefit each other. Rosemary’s strong scent can deter pests that typically target carrot plants, providing a natural protective barrier.

In return, carrots do not compete with rosemary for sunlight, as they grow underground. This allows rosemary to receive the full benefit of sun exposure.

Their partnership promotes a balanced garden ecosystem, where each plant supports the other’s growth, making them a surprisingly effective duo.

Strawberries

Strawberries and rosemary make a visually appealing pair, with strawberries offering ground cover that benefits rosemary’s growth. The sprawling nature of strawberries helps retain moisture in the soil, aiding rosemary’s health.

This arrangement also provides strawberries with the aromatic protection of rosemary, potentially deterring pests that may otherwise attack the fruit.

Together, they create a harmonious garden scene that is as beautiful as it is functional, supporting each other’s needs.

Avoid: Mint

Mint, while a useful herb, is not a good neighbor for rosemary. Its invasive growth can quickly overtake garden spaces, crowding out other plants like rosemary.

The aggressive nature of mint can lead to competition for nutrients and space, hindering rosemary’s development. Additionally, mint prefers more moisture than rosemary, making them incompatible.

To avoid these issues, it’s best to plant mint in a separate container or area, ensuring both herbs can thrive without interfering with one another.
