To care for Dracaena lucky bamboo, provide bright, indirect light, keep its roots submerged in water with pebbles or in a moist, well-draining soil, and use distilled or filtered water to avoid chlorine and fluoride damage. Maintain warm temperatures (65–90°F), change water weekly or when murky, and rinse roots and pebbles periodically to prevent algae and salt buildup. Fertilize sparingly with an aquatic plant fertilizer, rotate the pot monthly for even growth, and prune any yellowing leaves or stems to encourage new growth.
