Yup, Jiffy is right. I just looked it up.
here's what I found:
Proper Care
Light Close to an east or west window is ideal for dracaenas. They like bright light but should not be placed in direct sunlight. The best position is one that gets two or three hours a day of sunlight filtered through a translucent blind or curtain. Outdoors D. marginata should be placed in a shaded area as direct sunlight will damage the leaves.
Temperature Dracaenas do well in normally warm temperatures. They like high humidity, so place plants on trays or saucers of moist pebbles or damp peat moss and occasionally mist-spray the foliage.
Watering Water plentifully during the active growth period to keep the soil moist at all times. Never allow the pot to stand in water. During the rest period, allow the top 1 inch (2.5 cm) of the potting mixture to dry out between waterings.
Propagation Propagate dracaena by taking tip or stem cuttings or basal shoots in
spring or summer. Cuttings should be young and 3 – 6 inches (7 – 15 cm) long. When planting make sure the cuttings are placed the same way up as the stem originally grew. Place each cutting or shoot in a pot of slightly moistened soil and close in a plastic bag and keep in a warm, partially shaded area until rooted. Do not water while the cutting is in the plastic bag. After rooting has occurred, water the plant moderately, allowing the top half-inch (1.2 cm) to dry-out between waterings. Re-pot into one size larger when roots appear on the surface of the mixture, and treat as a mature dracaena. Dracaena is a terrific plant for bonsai as it is very easy to wire and shape.
Potting/re-potting Dracaenas do not require frequent re-potting to sustain growth.
Feeding Feed with standard liquid fertiliser regularly except in the fall and winter.
Special Problems
Leaves with brown tips and yellow edges. The most likely cause is dry air, cold draughts, or underwatering.
Leaves with brown spots. Underwatering. Keep dracaenas moist at all times.
As with all plants, Dracaena plants tend to become dusty overtime. Spray leaves with water or wash leaves gently with a damp cloth. When sponging off leaves of the larger plants, use one hand to support each leaf so as not to put too much strain on the stalk.
