As a food, lemongrass can be used as an ingredient to provide a citrusy aroma and flavor.  It makes a delicious and healthful beverage when brewed as a tea, as well.  To impart its taste and smell during grilling, the stalks can be tied together and lightly beaten with a tenderizing hammer to release their oils before using them to apply sauces to grilling meats.

Raising lemongrass at home will enable the gardener to utilize the herb for all of these functions and more.  In temperate regions where lemongrass is a four season plant, harvesting can occur at any time the fresh flavor or scent is desired.  Otherwise, it can be enjoyed visually as a landscape grass.

Cooler regions will require that the lemongrass be grown in a container to allow it be brought indoors over the winter.  Kept in full sun and given frequent watering, the plant will flourish.  In the fall, bring it inside and trim the stems back to about 8.  (Note:  do not discard these stems!!  Use these to brew tea, add to soup stocks or dry it and chop finely for use as a sprinkle seasoning for meats or vegetables, or even add it to desserts for a fresh, citrus flavor.) After cutting back, place the container in a cool spot away from direct sun, and minimize watering to allow the plant to go dormant.  Late winter will stimulate the plant into growth; when this growth is noted, return the plant to a sunny window and resume watering to encourage optimal growth.
