Companion Planting Rosemary — Best Plants to Grow with Rosemary
Companion planting rosemary isn’t just about aesthetics — it’s a science of balance. Rosemary’s aromatic oils repel pests, attract pollinators, and even improve the flavour and resilience of nearby plants. With the right companions, this Mediterranean herb becomes a natural garden ally.Why Rosemary Makes an Ideal Companion
- Natural pest control: The scent deters cabbage moths, carrot flies, and aphids.
- Pollinator magnet: Rosemary flowers attract bees and beneficial insects.
- Low nutrient demand: It won’t compete aggressively with neighbouring plants for soil fertility.
- Heat and drought resilience: Complements other dry-loving Mediterranean herbs and veggies.
Best Plants to Grow Beside Rosemary
1. Vegetables
- Cabbage, broccoli & cauliflower: Rosemary’s strong scent repels cabbage moths and whiteflies.
- Carrots: Masks carrot fly odour and improves yield when interplanted in alternating rows.
- Beans: Provide nitrogen that supports rosemary’s modest nutrient needs in lean soil.
2. Herbs
- Thyme & sage: Thrive in similar dry, sunny conditions and enhance each other’s oils.
- Lavender: Aesthetic match; shares identical watering and soil needs.
- Oregano: Forms a natural living mulch beneath rosemary shrubs, suppressing weeds.
3. Flowers & Ornamentals
- Marigolds: Pair beautifully for dual pest control — marigolds deter nematodes below soil level.
- Alyssum & yarrow: Attract hoverflies and parasitic wasps that protect nearby vegetables.
- Geraniums: Help repel beetles while complementing rosemary’s upright habit.
What Not to Plant Near Rosemary & Common Questions
- Basil: Prefers moist, nutrient-rich soil — opposite of rosemary’s dry conditions.

- Tomatoes: Require heavier feeding and more frequent watering, causing uneven soil moisture.
