Planting lemongrass in the pot is rather easy. What it require is a relatively warm temperature, above 20 C, and plenty of sunshine. the soil should not retain too much water.1. Prepare the pot, at least 8 inch in diameter and 6 in of soil. Let the soil set for a week or two with constant watering.
2. Get about three stalk of fresh lemongrass, make sure the bulb is still available.
3. Put the stalk in upright position in a shallow water. The water barely touches the stalk, leave them for about 3 days.
4. After 3 days, the roots should start to come out.
5. Make small holes for each of the stalk. The depth is about 2 inches, and the distant from other stalk is about 3 inches.
6. Firm up the soils, and water it until the water comes out from the bottom of the pot.
7. Leave it in the sun,and water it one a day, either morning or late afternoon.
Good luck.
