Our bamboo was planted in pots from slips two years ago and we finally we got to plant it out in September last year. All 20 plants are thriving in their new home and have had serious growth spurts through our rainy season - testament to the fact that this is the fastest growing plant in the world. 30cm a day no joke! . Last month we planted 35 vetiver slips in between the bamboo and everyone seems to be getting along nicely. Very happy with trials so far. . Please note this is CLUMPING bamboo (Bambusa balcooa) and is NOT INVASIVE!
