Bamboo is a type of grass that grows widely across Asia. There are even American varieties of bamboo, although they are quite rare. Many gardeners use bamboo as an ornamental grass for its exotic appeal and the amount of privacy it provides. Bamboo comes in many varieties and colors, from black to green to red, and from small to giant, but they all need the proper irrigation to grow well. Watering bamboo properly will depend on your climate and growing conditions.
Water bamboo two times a week for 5 minutes each watering using a hose. If you live in a wet climate you can water only once a week, but if you live in a dry climate you need to water more often, up to five times per week.
Hold the hose at the base of the bamboo plant and turn it on. Allow the water to soak into the ground. The water needs to soak into the bamboo's rhizome that may be 3 feet under the soil.
Mulch the ground around the base of the bamboo or allow the bamboo leaves to form natural mulch. This holds moisture in the ground, which allows you to water less often.
Check your bamboo every day between waterings. If the leaves curl, the bamboo needs more water more often. Increase your watering schedule by 1 day per week until the leaves uncurl.
