Bamboo is a decorative grass with a wide variety of commercial uses. The types range from dwarf bamboo, which grows to just 1 foot, to massive timber bamboos that grow to more than 100 feet tall. Bamboo grows from mountainous climates to tropical jungles. Dwarf bamboo, often called "lucky bamboo," is a popular houseplant. It is grown in water gardens and in pots. Bamboo that is under-watered or receives too much strong sunlight or not enough sunlight responds with wilted, brown leaves, and wrinkled, dehydrated stalks. A number of remedies can be employed to revive bamboo.
Reviving outdoor bamboo
Cut off the flowering stems of large bamboos, removing the stem portion down to the main stalk.
Chop the rhizomes, or horizontal underground stems, into sections that are 8 to 12 inches long with a sharp-edged hoe or ax.
Apply an all-purpose, organic lawn fertilizer that is high in nitrogen. A 10-6-4 formula works well. One pound of fertilizer, applied once as per manufacturer's instructions, will supply five large outdoor bamboo plants. Water generously. The bamboo may revive with continued care.
Reviving Indoor Bamboo
Remove the bamboo from the pot, or remove it from the water garden and rinse thoroughly.
Submerge the bamboo stems in water up to the first leaves. A tall narrow vase or pitcher works well. Bamboo with any section of green stalk should revive.
Remove leaves that turn yellow. If any stalks become soft or turn yellow, remove and discard them; they will not revive. Bamboo with completely dead culms, stalks and leaves may still revive from the rhizomes. Leave the bamboo submerged for a few weeks to give it adequate opportunity to revive.
Fertilize with all-purpose granular fertilizer when the bamboo produces new growth. Bamboo is a grass and responds well to high nitrogen grass fertilizer; a 10-6-4 formulation is recommended. Mix the fertilizer with water as per concentration instructions on the package. Allow the bamboo to develop a hearty root system.
Transplant to a large pot with new, all-purpose soil or to a clean water garden.
