Lemon Grass

Growing Lemon Grass
Lemon grass locally known as grass tea is widely used as a herb in Asia and Caribbean cooking. It has a lemony flavour and can be dried and powdered or used fresh. The stalk itself is too hard to be eaten, except for the soft inner part. However, it can be finely sliced and added to recipes. It may also be bruised and added whole as this releases the aromatic oils from the juice sacs in the stalk.

Lemon grass has long, thin, sharp grass-like gray-green leaves, and a spring onion like base. Under ideal conditions, it can grow up to six feet.
The lemon grass has been mainly grown for domestic use but of a number of farmers has started growing it on commercial scale. There is a big demand for the aromatic plant, especially among street side tea brewers in urban areas
