Known for its culinary and medicinal uses, it thrives in moist, light (sandy) to medium soil with a pH between 6.5 and 7. This herbaceous plant, which can grow up to 0.5 meters tall, is often propagated by direct sowing of seeds after the last frost date.

Cultivation

Basil thrives in light conditions that are moderately bright but not too intense, making it suitable for partial shade or full sun. It prefers well-draining soils that are light (sandy) to medium-textured and has a pH between 6.5 and 7. Water basil when the soil feels dry to the touch, ensuring it remains moist but not waterlogged. Basil is hardy in temperate regions with zones ranging from 5 to 10. It can be propagated by direct sowing of seeds after the last frost date, with plants spaced about 15cm apart. Harvest its leaves and seeds for culinary use.
