Seed Depth: 1/4 inch

Seed Spacing: 18–24 inches

Row Spacing: 24–30 inches

Sunlight: Full sun

Days to Sprout: 14–28 days

Days to Maturity: 80–100 days

Growth Habit: Woody, perennial herb

Sunlight: Requires full sun for optimal growth, at least 6–8 hours daily.

Soil Type: Prefers well-drained, sandy or loamy soil with a pH of 6.0–7.5.

When to Plant: Start seeds indoors 8–10 weeks before the last frost or sow outdoors in late spring when the soil is warm.

Direct Sowing: Sow seeds 1/4 inch deep and thin seedlings to 18–24 inches apart.

Indoor Sowing: Use seed-starting trays with light soil; rosemary seeds germinate slowly, so patience is key.

Succession Planting: Not typically needed, as rosemary is a perennial herb.

Watering: Water moderately; allow soil to dry slightly between waterings.

Fertilizing: Use a balanced fertilizer sparingly; too much can reduce flavor and aroma.

Pruning: Regularly prune to maintain shape and encourage new growth.

Pest and Disease Control: Watch for spider mites and powdery mildew; ensure good airflow around plants.

When to Harvest: Begin harvesting leaves once the plant is established, typically 80–100 days after planting.

How to Harvest: Snip small sprigs or individual leaves as needed; avoid heavy pruning in the first year.

Seed Collection: Rosemary rarely produces seeds; propagation by cuttings is often more reliable.

Storing Seeds: If seeds are collected, store in an airtight container in a cool, dry place.
