Rosemary Growing Guide for Zone 9

Planting Time: In Florida, plant rosemary in early spring or fall. Rosemary thrives in warm weather and can tolerate the heat of summer and mild winters, making it suitable for year-round growth in zone 9.

Soil: Rosemary prefers well-draining soil with a pH between 6.0 and 7.5. Adding sand or gravel to the soil can improve drainage. Compost or well-rotted manure can improve fertility and structure.

Sun: Rosemary grows best in full sun, requiring at least 6-8 hours of direct sunlight daily.

Watering: Keep the soil consistently moist but not waterlogged. Rosemary is drought-tolerant once established, but regular watering is necessary for young plants. Allow the soil to dry out between waterings.

Spacing: Plant rosemary seeds or transplants 24-36 inches apart. Rosemary can grow quite large, so proper spacing ensures adequate air circulation and room for growth.

Fertilization:
N-P-K Ratio: Rosemary benefits from a balanced fertilizer with a slightly higher nitrogen content to support healthy growth, such as 10-10-10 or 16-16-8.

When to Add:

• Before Planting: Apply the fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

• Early Spring: Reapply the fertilizer in early spring as new growth begins.

• Mid-Growing Season: If needed, reapply the fertilizer lightly every 4-6 weeks to support continued growth.

Application Tips:

• Follow the directions on the fertilizer package to avoid over-fertilization.

• Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

Additional Tips:

• Rosemary grows best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

• Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

• Ensure that rosemary receives consistent moisture, especially during the growing season, to prevent stress and promote healthy growth.

Cut the stems as needed, ideally before the plant starts to flower, by snipping them with scissors or pruning shears. Regular harvesting encourages bushier growth. Cut sprigs in the morning when the essential oils are at their peak for the best flavor.

Herb Uses:
