What is the Climatic Requirement for Growing Holy Basil?

Holy basil plants prefer long day times with high temperatures and humid conditions for healthy plant growth and high yield of Tulsi essential oil. Tulsi can be cultivated both in tropical and sub-tropical climatic conditions. The Basil crop requires an average annual rainfall of 90 to 120 cm. Basil can be grown up to an altitude of 900 meters (mean sea level). Basil can tolerate drought and frost to a certain extent. Even Tulsi can be grown under partial shade conditions, but expect lower oil yields.
