Bamboo plants can survive with little attention but will really thrive when they are fed. Whether an indoor ornamental bamboo plant or a wall of bamboo plants in the yard, help your bamboo grow into strong, healthy and beautiful plants with regular feedings, especially during the growing season. Bamboo plants are not picky and will respond to several different sources of food.
Feed your bamboo plants a lawn fertilizer high in nitrogen with a formula of 21-5-6. A time-release palm and ornamental fertilizer with a 13-3-13 formula also will work.
Spread a 2- to 3-inch layer of compost or aged manure around the base of your bamboo for a more natural source of bamboo food. Mulch is beneficial to the growth of bamboo plants and helps them retain moisture.
Feed your bamboo plants with water from a fish tank or fish pond. The waste in fish-tank or pond water is natural food for the bamboo. Similarly, add a few drops of aquarium plant food to your bamboo plants' water once a month.
