Lemongrass is a culinary herb and a ornamental grass. Being a true tropical, lemongrass requires warm temperatures year-round. In climates where winters are cold and frozen, plant lemongrass in a pot and bring it inside for the winter months. Lemongrass grows in clumps and can get 6 feet tall and 6 feet wide. Harvest the stalks when they are about the thickness of your baby finger. The lemony flavor adds zest to your favorite menus, and harvesting a few stalks will keep the plant a manageable size.

Fill a 1-gallon pot with a mixture of equal parts top soil and rich, well-rotted compost. Make a hole in the center of the pot big enough for the root ball of your lemongrass plant.

Pull the clump of lemongrass from the nursery pot. Turn the plant on its side and, grasping the base of the stems, wiggle it back and forth until it comes free from the pot.

Place the root ball into the new planting pot with the base of the stems 1 inch below the lip of the pot. Push the soil around the root ball so that it is buried to the same depth it was in the nursery pot. Pat down the soil with the flat of your hand to secure the root ball in the soil.

Water immediately after planting so the soil is damp all the way through. After that, water every other day to keep the soil around the roots consistently damp. Mist the leaves with water from a hose or spray bottle every other day. Fertilize every two weeks with a balanced fertilizer.

Bring the lemongrass plant indoors before the first frost. Place it in a sunny window or in a heated greenhouse where the temperature will remain above 65 degrees Fahrenheit for the winter. Keep the roots damp and mist the leaves daily during the winter months. Move the pot back outside in the spring when the weather is consistently above 65 degrees.
