You will need: Fresh lemon grass stems, glass or jar of water, sharp knife, 3½ in (8 cm) plastic pots, soil-based potting mix, liquid houseplant fertilizer, decorative indoor planter.
Root the stems
Buy fresh lemon grass stems and put the bulbous ends in a jar of water. Stand them on a bright windowsill for a few weeks until a good root system has developed. Change the water weekly.
Trim and plant
Fill small pots with soil-based potting mix. Trim off the top of each stem and pot the young plants up. Water well, and keep on a warm, sunny windowsill, or in a greenhouse.
Water well during summer, and apply a liquid fertilizer every two weeks. Pot them on into larger pots as they grow. In winter, keep the soil just moist. To harvest, cut the stems close to the roots.
