How to Grow Rosemary

Rosemary, with its fragrant leaves and cooking versatility, is a wonderful herb to grow. Whether you’re an experienced gardener or a novice, growing rosemary is a rewarding experience. In this comprehensive guide, we’ll explore the step-by-step process of how to grow rosemary, from selecting the right variety to caring for your plant and enjoying its aromatic bounty in the kitchen.

1. Choosing Rosemary Varieties

Rosemary comes in various varieties, each with its unique characteristics. Common varieties include:

  • Common Rosemary: The standard variety with aromatic leaves.
  • Prostrate Rosemary: A trailing variety, ideal for ground cover or container gardens.
  • Tuscan Blue Rosemary (Rosmarinus officinalis ‘Tuscan Blue’): Known for its upright growth and intense fragrance.

Choose a variety based on your space, gardening preferences, and culinary needs.

2. Starting from Seeds or Cuttings

Rosemary can be grown from seeds or cuttings. Here’s how to start each:

  • Seeds: Start seeds indoors in late winter or early spring. Rosemary seeds require warmth and light to germinate. Transplant seedlings outdoors after the last frost.
  • Cuttings: Propagate rosemary from cuttings taken from a healthy, established plant. Dip the cut end in rooting hormone and plant it in well-draining soil. Keep the soil consistently moist until roots develop.

3. Sunlight and Soil Conditions

Rosemary thrives in specific sunlight and soil conditions:

  • Sunlight: Plant rosemary in a location that receives at least 6 to 8 hours of direct sunlight daily.
  • Well-Draining Soil: Rosemary prefers well-draining soil with a slightly acidic to neutral pH. Sandy or loamy soil is ideal.

4. Planting Rosemary

Proper planting ensures a strong start for your rosemary plant:

  • Spacing: Plant rosemary 24 to 36 inches apart to allow for proper air circulation and prevent overcrowding.
  • Planting Depth: Set the plant in the ground at the same depth it was in its nursery container. Water the plant thoroughly after planting.

5. Watering Rosemary

While rosemary is drought-tolerant, proper watering is essential:

  • Watering Frequency: Water deeply but infrequently. Allow the top inch of soil to dry out between waterings.
  • Avoid Overwatering: Rosemary doesn’t tolerate waterlogged soil, so ensure that the soil has good drainage.

6. Mulching and Feeding

Mulching and feeding contribute to the overall health of your rosemary plant:

  • Mulching: Apply a layer of organic mulch around the base of the plant to retain moisture, suppress weeds, and regulate soil temperature.
  • Fertilizing: Rosemary doesn’t require heavy feeding. Apply a balanced fertilizer in the spring, and avoid excessive use of nitrogen.

7. Pruning and Shaping Rosemary

Regular pruning helps maintain the shape and health of your rosemary plant:

  • Remove Dead Growth: Trim away dead or woody stems to encourage new growth.
  • Shaping: Prune the plant to maintain the desired shape. Rosemary can be shaped into hedges, topiaries, or left to grow naturally.

8. Protecting Rosemary from Pests and Diseases

Rosemary is generally resistant to pests and diseases, but some care is needed:

  • Pest Management: Keep an eye out for pests like aphids or spider mites. Insecticidal soap or neem oil can be used for control.
  • Disease Prevention: Ensure proper air circulation by avoiding overcrowding. Rosemary is susceptible to root rot in overly wet conditions.

9. Harvesting Rosemary

Knowing when and how to harvest rosemary ensures optimal flavor and fragrance:

  • Timing: Harvest rosemary sprigs once the plant has become established, usually after six months.
  • Cutting Method: Use sharp scissors or pruning shears to cut the sprigs. Trim no more than one-third of the plant at a time.

10. Drying and Preserving Rosemary

Preserving rosemary allows you to enjoy its flavor and aroma throughout the year:

  • Air Drying: Bundle fresh rosemary sprigs and hang them upside down in a dry, dark place. Once dry, store the leaves in airtight containers.
  • Freezing: Freeze rosemary leaves in ice cube trays with water or olive oil. Pop out the cubes and store them in freezer bags.

11. Growing Rosemary in Containers

Rosemary adapts well to container gardening, making it suitable for small spaces:

  • Container Size: Choose a container with good drainage that’s at least 12 inches in diameter.
  • Potting Mix: Use a well-draining potting mix with added perlite or sand.
  • Indoor Growing: Rosemary can be grown indoors in a sunny location. Provide adequate sunlight or supplement with a grow light.

12. Overwintering Rosemary

In colder climates, protecting rosemary from frost is essential:

  • Mulching: Apply a thick layer of mulch around the base of the plant in late fall to insulate the roots.
  • Covering Plants: Consider covering outdoor plants with burlap or frost blankets during extreme cold spells.

13. Culinary and Medicinal Uses of Rosemary

Rosemary is not only a culinary delight but also has medicinal properties:

  • Culinary Uses: Add fresh or dried rosemary to a variety of dishes, including meats, roasted vegetables, and bread.
  • Medicinal Properties: Rosemary has anti-inflammatory and antioxidant properties. It can be used in teas or as an infused oil.


Growing rosemary brings the joy of cultivating a versatile herb that enhances both your garden and your culinary creations. From choosing the right variety and providing proper care to harvesting and preserving, each step in the process contributes to a thriving rosemary plant. So, whether you’re garnishing a dish or enjoying the fragrance in your garden, the journey of growing rosemary is an aromatic adventure worth savoring. Happy rosemary growing!
