Dracaena marginata, more commonly known as a dragon tree, is an attractive plant with green sword-like, red-edged leaves. Native to Madagascar, the eye-catching spiky tree is known as a great entry plant for household gardeners—it's easy to care for, drought-tolerant, and nearly indestructible.
They should be planted in well-draining soil and watered regularly during their growing season. Though they can thrive in a variety of light conditions, they do best with indirect bright light. Dragon trees grow best in bright light but can also survive in partial shade. Keep in mind, plants kept in lower light situations will grow slower and produce smaller leaves with less intense color. Additionally, take care not to place your dragon tree in a spot that receives direct rays of sunlight—its foliage can burn easily.
Like with many drought-tolerant plants, it's easy to over-water the dragon tree. To ensure you don't drown it, wait until the top half of the soil is dry before watering (this can often take three weeks or more). If the plant develops brown tips on its leaves, that's usually a sign that it's either receiving too much water or that the water you're using has too much salt or fluoride, which can cause discoloration. To avoid fluoride, water your dragon tree with distilled or non-fluoridated water.
