It seems you are in a zone where bamboo will grow, but if you would consider adding your USDA grow zone to your profile it would help whenever you ask about plants. (I'm used to abusing grow zones and pushing the boundaries)
You want 4" diameter canes at maturity?
For construction, making pipes, making vessels? Or just nice and tall for privacy perhaps first and foremost?
I have 20' x 3' of clumping bamboo. Thick, woody canes (1-2 inches in diameter) with lush, evergreen canopies. Ideal for decorative privacy screens, furniture or outdoor arbors. I live in West Hollywood, CA
I am looking to remove all the bamboo and have it hauled away. I understand the value of this bamboo, but it is of no value to me and just want it gone.
