Herbs are rosemary’s natural family. They often enjoy the same growing conditions.
- Sage: Both are Mediterranean herbs that love full sun and dry soil. They make a beautiful, drought-tolerant pairing.
- Thyme: This low-growing herb is perfect for the ground around rosemary. It helps suppress weeds and enjoys the same conditions.

- Onions and Garlic: These strong-smelling alliums complement rosemary’s pest-confusing abilities. They create a protective barrier.
Why These Pairings Work
The main benefit is pest control. Rosemary’s pungent smell masks the scent of vulnerable vegetables. This makes it harder for pests to find there target. It also attracts beneficial insects like bees and predatory wasps.
Flowers to Grow With Rosemary
Don’t forget flowers! They add beauty and bring in helpful bugs.
- Marigolds: A superstar companion. Their roots release a substance that nematodes, and they repel many other insects.

Plants to Avoid Near Rosemary
Not every plant is a good match. Rosemary has specific needs that some plants can disrupt.
- Mint: Mint is far too invasive and loves moist soil. It will quickly overtake rosemary’s space and can cause root rot issues.
- Basil: Basil needs consistent moisture and rich soil, the opposite of rosemary’s preference for dry, lean conditions.
- Cucumbers and Pumpkins: These heavy feeders and water-lovers will not thrive in the dry soil rosemary requires.
- Potatoes: They have different watering needs and may compete for resources, stunting each others growth.
How to Plant Rosemary With Companions
Follow these simple steps for success. Planning is the most important part.
- Check Your Conditions: Ensure you have a full sun location (6-8 hours) with very well-drained, slightly sandy soil. Amend clay soil with grit or sand.
- Plan Your Layout: Sketch your bed. Place rosemary in the center or at the north side so it won’t shade smaller plants as it matures.
- Mind the Spacing: Rosemary can grow quite large. Give it at least 2-3 feet of space. Plant companions around its drip line, not right at its base.
- Plant at the Right Time: Plant rosemary and its companions after the last frost when the soil has warmed up. This is crucial for Mediterranean herbs.
- Water Wisely: Water new plants regularly until established. Then, let the soil dry out completely between waterings. Overwatering is the main killer of rosemary.
Container Companionship
If you’re growing rosemary in a pot, you can still use companion planting. Choose a very large container with excellent drainage. Good pot-mates include thyme, oregano, or marigolds. Avoid putting to many plants in one pot, as they will compete for water and nutrients.
Caring for Your Rosemary Companion Garden
Once established, this garden is low-maintenance. Here’s what to focus on.
- Pruning: Regularly harvest or trim your rosemary to keep it bushy and prevent it from becoming woody and leggy. This also helps it’s shape.
- Feeding: Go easy on fertilizer. Rosemary thrives in lean soil. A light application of compost in spring is usually sufficient for the whole planting area.
- Weeding: Keep the area around your plants clear of weeds, especially when they are young. This reduces competition for water.
- Winter Care: In colder climates, protect rosemary with mulch or move pots to a sheltered location. Most of its companion herbs have similar hardiness.
Common Problems and Solutions
Even with good companions, issues can arise. Here’s how to handle them.
- Yellowing Leaves: This is almost always a sign of to much water or poor drainage. Check your soil and cut back on watering.
- Powdery Mildew: Improve air circulation by pruning and ensuring plants aren’t overcrowded. This is rarely a problem with rosemary itself but can affect nearby plants.
- Few Flowers: Means it needs more sunlight. Ensure nothing is shading your rosemary during the day.
- Pests: While rosemary repels many pests, spider mites can sometimes be an issue in hot, dry weather. A strong spray of water can dislodge them.
