7 Best Rosemary Companion Plants to Help Repel Pests

1. Lavender ('Betty's Blue' English Lavender)

Growing lavender and rosemary together makes sense due to their shared Mediterranean origin and similar care requirements. Both plants thrive in well-draining soil and require minimal water. When planted together

2. Brassicas

Brassicas, such as cauliflower, Brussels sprouts, and cabbage, often suffer from pests that damage leaves and ruin harvests. Growing rosemary near brassicas can naturally repel these pests, particularly cabbage moths

3. Sage

Sage and rosemary make excellent garden companions due to their similar growing needs. Both herbs prefer sun and well-draining soil, and they can thrive together in a spacious planter if garden space is limited.

4. Carrots

Carrot flies are notorious pests for carrot plants, laying eggs that hatch into larvae which damage the carrot roots. Planting rosemary near carrots can help deter these pests. The strong aroma of rosemary masks the scent of carrot leaves

5. Oregano

Oregano is another herb that pairs well with rosemary, sharing similar sun and soil preferences. Both plants thrive in bright sunlight and relatively dry conditions, making them low-maintenance companions.

6. Beans

Bean beetles pose a significant threat to bean plants, causing extensive damage and reducing productivity. Rosemary’s strong scent can help protect bean plants by masking their presence and making it harder for beetles to find them.

7. Thyme

Thyme, like rosemary, thrives in sunny locations with low water requirements. It can be grown in pots or herb beds alongside rosemary, and low-growing varieties of thyme can serve as ground covers to suppress weeds around rosemary plants.
