Growing lemongrass is child’s play. All you need to do is plonk the stalks that you buy at the supermarket into a jar filled with about an inch or so of water and just watch it grow! Within just two days you will see the roots sprout and you know you’re on your way to a bountiful lemongrass garden.
Just keep changing the water every day or every second day at most. In about three to four weeks, the lemongrass would have grown about 2 inches of roots. Now is when you can transfer the lemongrass sapling to the soil. Keep it watered well, but make sure the soil isn’t soaked in water. It can withstand a good amount of sunlight as well.
