Grow ginger is really easy!!!
All you have to do is to buy some dry ginger roots from your local groceries shop.
Cut a small piece and put it in a glass of water for around 3 hours. Then put in a mini grow house.
Cover it with the soil and spray a bit of water on top of it.
After 2 weeks you should see some green sprout, then you can transfer it in a big pot.
The plant will grow pretty fast and after a few month you can cut the root in two, and put back the plant in the pot.
Then you can enjoy the other half for cooking.
