Lemongrass is a useful plant that can be used in cooking and to make refreshing lemongrass drinks. It is also a natural mosquito repellent. The good news is Lemongrass is very easy to regrow.
Regrowing Lemongrass in 2 Weeks
We bought some Zenxin brand organic lemongrass from the supermarket (available in Giant or Cold Storage in Singapore) to make Tom Yum.
We cut the top off to cook with and kept the bottom 2 inches to regrow.
The lemongrass was placed in a container with water, which was changed every 2 or 3 days (or whenever I remembered). Many plants can be placed in water initially in order to root the plant. These include bulbs like lemongrass and spring onions, and stem cuttings from plants such as kangkong, mint and basil.
So in just 2 weeks, the lemongrass has regrown significantly. This is once of the easiest and quickest plants to grow from what would otherwise be discarded kitchen scraps.
Another good thing is that you will have a virtually unending supply of lemongrass. Just cut off what you need and the lemongrass will keep regrowing!
