Grow lucky bamboo in low or medium light for best results. It can take a high-light spot, but lucky bamboo doesn't like direct sun so it's best to protect it with a sheer curtain to diffuse the light. You'll often see lucky bamboo sold without soil. The stems may be submerged in water and pebbles, gravel, marbles, or even colorful gels. Lucky bamboo is happiest when you keep the stems submerged. Some people like to use rain water to reduce the chemical content in the water, but for the most part, this plant grows just fine in regular tap water. If you wish to fertilize your lucky bamboo, use a fertilizer for aquatic plants and follow the directions on the fertilizer package. If your lucky bamboo outgrows its container, you can easily transfer it to a larger container. Pack in pebbles, stones, or other materials to help keep the stems upright.
