Cymbopogon citratus. Lemongrass is a tropical plant from the grass family (Poaceae) that will grow well in temperate regions if given the right conditions. Sow Lemongrass seeds indoors in late winter using bottom heat or a seedling heat mat. Maintain moist conditions and a temperature around 21°C (70°F), and the seeds will germinate in 5 to 21 days. Be sure to use sterilized seed starting mix, and either a clear dome over your seedling tray, or sealed into a plastic bag to maintain moisture. Transplant outdoors or into containers in full sun once the weather has warmed up in early summer. At the end of summer move container plants into a frost free environment with good air circulation. Reduce watering to almost none, making the soil barely moist once a week.
When using Lemongrass in the kitchen, remove any loose, outer layers. Either use whole pieces, crushed slightly with a pestle or under the back of your cleaver, or slice sections very thinly in cross section. This will help break up the strong fibres of the grass stalks.
Lemongrass is a tropical grass that thrives in summer heat. It is well suited to container growing, and ideal for greenhouse cultivation. It can be grown as a perennial in our climate, but care must be taken to control moisture in the soil over winter, and to provide protection from frost. It is somewhat challenging to grow, but the reward is fresh, strongly aromatic stalks with very minimal carbon footprint. Hopefully these helpful tips will teach you how to grow lemongrass from seed.
