Typical of the Curcuma plant is that it gives you so much and asks for so little. It prefers a light, sunny location on the window sill but can also be kept in a sun lounge or on a balcony where the temperature will not drop below. Water your Curcuma twice a week, and add a little liquid plant food to the water once every two weeks. A Curcuma can produce 2 to 5 new flowers, each of which lasts for about 3 weeks.
