Curcuma Rhizomes prefer medium moisture, well-drained soils in full sun to part shade. For indoor planting make sure your container should contain drainage holes. Some pebbles or little rocks in the bottom of the container can help and improve the drainage. Keep the soil moist but do not overwater. Use humus rich compost with equal quantity of horticultural sand mixed to make the compost well drained and light. Slow release fertilizers can be used.

The general rule of thumb for planting spring bulbs is to plant two to three times as deep as the bulbs is tall. This means most large bulbs like tulips or daffodils will be planted about 8 inches deep while smaller bulbs will be planted 3-4 inches deep. Planting depth is measured from the bottom of the bulb.
