About Rosemary
Rosemary is a Mediterranean herb that has become popular in India through hair-care trends and continental cooking. Its needle-like leaves contain rosmarinic acid and carnosic acid, both strong antioxidants. Because it comes from a dry, cool climate, rosemary is one of the trickier herbs to keep alive in humid Indian plains — it grows far better in hill stations, Bengaluru or Pune.
Botanically known as Salvia rosmarinus, it belongs to the Lamiaceae family. It is native to Mediterranean and grows best in a mediterranean climate. The parts most often used are the leaves, flowers and oil.

How to Grow Rosemary
| ☀️ Sunlight | Full sun, 6–8 hours. |
| 💧 Watering | Water sparingly — only when the top half of the pot is dry. Overwatering is the most common cause of death. |
| 🪴 Soil | Sandy, gritty, fast-draining soil; add sand or perlite to the potting mix. |
| 🌱 Propagation | Softwood cuttings (10 cm) rooted in a sand-cocopeat mix; seeds are slow and unreliable. |
| 📅 When to plant (India) | Plant October–February in the plains to establish before summer heat and monsoon. |
| 🏡 In pots / at home | Terracotta pots are best because they dry out quickly. Shelter from heavy monsoon rain. |
Precautions & Safety
- Undiluted essential oil can irritate the skin and should not be swallowed.
