Dragon Tree Watering: Keep soil slightly moist. Can become dry regularly. Needs less water during the winter. Water with filtered water. I water mine every three to four days with just enough water to moisten the soil. Temperature: Ideal between 65°- 75°F (18°- 24 °C). They will live through much colder temperatures during winter (as I have observed), but keeping them in optimal health requires the room to be no less than 50°F (10°C). Light: Bight light is good, but direct sunlight can damage the leaves. Air Humidity: Normal household humidity is fine. Misting the leaves is advised. They like fresh summer air from an open window, but not stuffy-hot rooms from heating systems. Propagation: Cutting and re-planting stem cuttings a couple of inches long. Apply root hormones and give it a few weeks for them to begin rooting. Re-Potting: These can be re-potted every two years during spring if needed. They seem to do okay with becoming root bound.
