It is hardy and can grow in poor soils, as well as on eroded slopes because of their soil-binding properties. This grass can be harvested around 90 days after planting. When it is harvested, the cutting is taken 4 inches from the ground, allowing it to grow again. Most lemongrass is sold to the cosmetic oil industry, but some is sold fresh or dried for culinary purposes. 

India is the top producer of this grass, producing over 2 million pounds of it every year. Other lemongrass producing countries include China, Malaysia, Sri Lanka, and Cambodia. Guatemala is the largest exporter of this grass in the world.

When cooking with this grass, the bulbs must be cut off before using, followed by the stalk being bruised or crushed after the husk is removed. This grass needs to be loosely wrapped and stored in the refrigerator, where it can remain fresh for a few weeks, although it can also be frozen and stored.
