Lucky bamboo plants require little care, making them ideal for people with brown thumbs. These plants just need clean water and sunlight to stay lush and green. They'll really thrive, however, if you provide occasional feedings.
The best way to keep your lucky bamboo plant healthy is to provide it with clean, filtered water and plenty of indirect sunlight. Lucky bamboo can survive for months or even years without plant food. Still, since the plants don't get nutrients from soil, they'll do best and live longest when given small amounts of plant food on an occasional basis.
It is safe to fertilize your lucky bamboo plant every couple of months, according to the University of Arkansas Division of Agriculture. Use one to two drops of liquid fertilizer designed for live, fresh-water aquarium plants, or dilute liquid houseplant food at a ratio of 1 part fertilizer to 10 parts water. Add one to three drops of the fertilizer right after a water change.
Excessive fertilizer can burn the roots and shorten the lifespan of your plant. Don't fertilize more often than every six to eight weeks. If you accidentally add too much fertilizer, change the water, and fertilize again. If you use tap water for your lucky bamboo, let it sit out overnight so some of the chlorine and other chemicals escape into the air. Those chemicals may also shock or burn the roots.
