Holy Basil (Ocimum tenuiflorum) is a highly aromatic, bushy herb that grows between 30–90 cm (1–3 feet) tall. It produces small purple or white flowers that attract bees and other pollinators. The leaves have a strong, clove-like scent and are widely used in Ayurvedic medicine. Holy Basil is a heat-loving plant that thrives in warm, humid environments with well-drained, fertile soil. It is often grown as a medicinal herb, companion plant, or natural pest deterrent. 🌞💧 Sun and Water Requirements: - Prefers full sun (at least 6–8 hours of direct sunlight daily). - Requires well-drained, fertile soil with moderate water needs. - Drought-tolerant once established but benefits from regular watering. ✂️🫘 Methods to Propagate: - Seeds: Direct sow after the last frost or start indoors 4–6 weeks before transplanting. - Cuttings: Can be propagated from stem cuttings placed in water or soil. - Self-seeding: Readily self-seeds in warm climates. 🧑‍🌾👩‍🌾 When to Harvest: - Harvest leaves regularly throughout the growing season for fresh use. - Flowers should be pinched off to encourage bushier growth. - Entire plants can be harvested before flowering for drying and medicinal use.
