Lemongrass grows best in warm, tropical, or subtropical climates with plenty of sunlight. It requires at least 6–8 hours of direct sun each day and thrives in fertile, well-draining soil rich in organic matter. Keep the soil consistently moist but not waterlogged, especially during the growing season. In cooler climates, lemongrass can be grown in containers and moved indoors before frost arrives, ensuring healthy growth year-round.
