If you live in a frost free area , you can grow this
plant outside. I planted mine outside in
zone 9 and it grew to be about 3 feet tall or you can grow it in a large pot as if you want a big
plant grow in a big pot as the leaves will turn brown from small pots and too much water or too little water. It is a grass and it can get rootbound and needs the same water care and light.
If you like Thai foods and have a Thai grocery store close,check out the lemon grass there as thats where I got my start from a small sprig of grass that had a root on the end, I also got Ginger and started it.
