Dracaena marginata plants can be used as table plants, but they are especially impressive as tall trees with multiple canes and hundreds of long, thin, green leaves trimmed in dark red. The canes are often thick, twisted, and woody, making them a desirable and expensive “specimen” plant. Dracaena marginatas, or Madagascar Dragon trees as they are sometimes called, are easy-care , durable, indoor plants well suited for offices and homes. NASA lists a Dracaena marginata as an excellent plant for removing harmful chemicals from the air.
Light: Dracaena marginata plants prefer medium light, but survive in low light situations. Lower light slows down the growth rate and reduces the size of new leaves. Direct sun burns the leaves.
Water: Over-watering causes root-rot and is the main reason a Dracaena marginata dies. Water well and don't water again until the top 50% of the soil is dry. In low light, this could take up to three weeks. Brown tips on the leaves indicate over-watering or too much fluoride or salt in the water. Never use water that has passed through a softener, it is too salty. If your household water has a lot of chemicals, allow it to sit out overnight before using it or use rain water or distilled water. This is a stalk plant, so it is common for the lower leaves to turn yellow and fall off if the plant is getting new leaves at the top. Numerous yellow leaves means the plant needs more water.
