Select rosemary seeds according to your climate and purpose. Choose 'Arp' or 'Salem' for cold areas, the standard for cooking, and 'Roseus' or 'Golden Rain' for aesthetics.
Rosemary needs well-drained soil with a pH of 5.5 to 7.0. If the pH is below 5.0, add 2.5t/ha of dolomite. It likes cool winters and mild summers under 30°C. It is best grown at 900 to 2500 m above sea level.
Rosemary grows from seeds or cuttings. Start seeds indoors in spring, then transplant. Cuttings are common in India. Water sparingly to avoid root rot, especially during rain.
Rosemary thrives without fertilizer but benefits from occasional plant food. It mostly relies on the soil it's planted in, with compost providing necessary nutrients.
Rosemary is drought-tolerant, needing minimal watering. Over-watering harms it. Bottom-watering, best for rosemary, keeps roots moist without saturating the surface.
Harvest rosemary mid-May to mid-summer. Cut shoots diagonally above woody areas with a sharp knife. Harvest evenly from all sides, shaping the plant.
