Hello,

My yard borders (along a chain link fence) a public park that gets a fair amount of foot traffic. I'm considering planting bamboo as a privacy screen. I've got ~80' length to screen off. My question is, how wide do I need to make the bed? What is the most narrow I can make this bed along the 80' length and still have a full privacy screen (blocking ALL view of the park). Would 2'x80' be adequate? How about 3'x80'? I'm going to plant both golden bamboo (phyllostachys aurea) and black bamboo (phyllostachys nigra) in this bed, with the black bamboo running along the side of the bed that's visible from the house. As it stands right now, I plan to use a 24" root barrier, although I can use a larger one if necessary. What is the narrowest I can get away with for this bed? Thanks!
