yet if I forget to join water the ends of the leaves turn brown. I use distilled sea which is the best an doesn't leave minerals adjectives over the stone and sides of the pot so I know the roots aren't clogged. I'd love to plant them in soil so they grow. Will they? Also I hear that larger bamboo can be grown outdoors contained by gardens. Where would I purchase that type? Thank you!
Answers:    I had equal problem. A girl I worked with bought one at impossible to tell apart time I did and hers grew a foot in 6 months! Mine didn't grow at adjectives, just a few untried leaves. Last month I added some liquid fertilizer and it started to grow. So you might want to try that. I'm not sure just about transferring into the ground.
Plant in pot will single grow a certain size, plant it contained by the ground for maximum growth
