Cultivation Details
Basil is a plant of the tropics, though it can also be grown in the subtropics and succeeds outdoors when grown as an annual in the warm temperate zone. In the tropics, it succeeds up to an elevation of 1,000 metres[1]. It grows best in areas where annual daytime temperatures are within the range 18 - 27°c, but can tolerate 7 - 36°c[2]. It is intolerant of frosts. It prefers a mean annual rainfall in the range 1,000 - 1,600mm, but tolerates 600 - 4,300mm[2]. Prefers a sunny, sheltered position[1]. Prefers a rich light well-drained to dry soil[3, 4, 5]. Prefers a pH in the range 6 - 7, tolerating 4.3 - 8.2[2]. The plant takes 70 - 110 days from germination to first harvest, and can thereafter be cut up to three more times at 60 day intervals, the harvesting taking place just before the crop starts flowering[2]. Average yield is 1.2 - 1.5 tonnes per hectare of dry, cleaned drug[2]. There are a number of different constituents that make up the essential oil in basil, and the proportions of these vary considerably between plants growing in different regions of the world[5]. From this variety many named varieties with differing flavour characteristics have been developed[6, 5].
Propagation
Seed - sow mid to late spring in a greenhouse and only just cover the seed. Germination is usually free and quick, prick out the seedlings into individual pots when they are large enough to handle. If growing basil outdoors, plant out after the last expected frosts.
