I have located some information on watering bamboo with a drip system, but we do not have a municipal water supply here to provide adequate pressure for one of these systems. We have a gravity fed good old fashioned garden hose taking rainwater from a 3,000 gallon tank. Thus far, I have only put 4 bamboo plants in the ground, the rest are still in pots. They were all 1 gallon pot size, so quite small. I have been watering them every morning, and so far so good. They have been in the ground for maybe 3 weeks. Are there any good guidelines for watering bamboos generally?
