Citronella grass is native to tropical Asia. It is fragrant and thrives in warm, tropical regions, including parts of the Nilgiris and other southern Indian areas. The grass can grow several feet in height. It prefers full sun to partial shade and moist, well-drained soil to grow. Citronella oil is extracted through steam distillation and is renowned for its distinct lemony scent. It is primarily valued as a natural insect repellent, particularly against mosquitoes. It is also incorporated in aromatherapy, and used as a component in soaps, candles, and other household products.

There is consistent demand for citronella oil from domestic and international market. High production and labour costs are making citronella production an expensive proposition. Cultivation areas have reduced and there is limited carry forward stock. While the supply is limited, buyers are actively trying to purchase product. This is driving citronella prices upward.
