Lemon Grass Growing Conditions

Grow in a frost-free place in full sun or light shade. The herb likes moist, well-drained soil that is slightly acidic. It grows best in warm, humid conditions. It can also be grown in a container or in the greenhouse. If you move your plant outdoors for the summer, allow it to acclimatize over a number of days, first placing it in shade, then moving it to part shade before giving it full sun.

Lemon Grass Cultivation

The plant can be grown from seed or division. The many varieties available, mostly used in commercial cultivation, do not come true from seed, and seeds germinate slowly, so vegetative propagation is usually preferred. Lift and cut apart clumps in early spring or fall. Space 3 feet apart. Lemon grass is clump forming and does not runner and become invasive like some grasses. Water regularly in summer.

Herbal Uses

Lemon grass gives a tropical feel to the garden. Plant it with other herbs, or near large leaved plants like castor bean and canna lily. It can also be used to as a backdrop in the perennial bed or to form a border to separate areas of the garden.

In cooking the bulbous stem is cut in to sections and cooked in the dish, then usually removed before serving because it is tough and fibrous. The soft inner part of the stem is sometimes finely sliced and added to soup.

The oil is used in perfume, makeup, soap, hair products, cleaner, antifungal agents, incense, and potpourri. It is also an effective and non-toxic insect repellent. It is used in aromatherapy.

Some gardeners have reported skin rashes when handling the plant.
