I am interested in planting some bamboo in my dog run (run measures approx 11'x25'). The floor of the run is made of stone blocks that are 16"x16". I have left two sections 32"x48" each in which I want to plant bamboo over the Easter weekend. This is a sunny, southern site in zone 6 between two houses. I looked through all bamboos online at bamboo garden and thought either the Phyllostachys aureosulcata Spectablis or Phyllostachys aureosulcata 'Harbin Inversa' would work well in this application as they are erect and not bushy, and the height of 26' is pretty close to what I am seeking (I really wanted 20' but this is close enough). Before I place my order, I have a few questions and appreciate any help:

1. Have I chosen the right bamboo? Which of the one of the two would you recommend over the other and why?

2. Typically, howmany canes come in the 2-gal size? 5-gal size?

3. Would you go with the 2-gal or 5-gal plants?

4. How many inches does this variety grow per year? Will it reach 26' in my application?

5. Do you think a pond-liner would work well as a barrier protection to keep the bamboo from running?

6. Is Bamboo Garden a good place to purchase online? Are there any other suppliers you would recommend?

Thanks a bunch, Cheryl
