Lemongrass is a key ingredient and widely used in many South East Asian cooking. I use them a lot when I cook curry’s, Tom yum soup, and sambal. It’s easy to grow them. I have grown mine from fresh lemongrass stalk they sell in supermarket. Just soak them in water till they start rooting. It takes about 10days. They grow well in a sunny spot indoors or outdoors. The don’t need much watering and just need some multipurpose or manure compost. I grow mine outdoors and come autumn when the night temperature starts to drop less 8 deg cel at night I did them up and put them in a sunny spot indoors. They freeze very well in the freezer once harvested. So come autumn one can either lift the lemongrass plant up and plant them indoors or simply just harvest them. They don’t grow much just stays dormant as there isn’t enough natural sunlight in the winter.
