I am considering bamboo as a screen between us and our neighbor. From our side yard, we look directly down into their front yard. I'd rather not. We are up-hill from them on their south side. I don't want to shade them out too much, so tall evergreens are not at the top of my list. I previously planted a single clumping bamboo as a bit of an experiment which has done well and has been well behaved (just gets fuller every year). I like the look of it in the wind and it provides some screening without being real heavy looking. The site is in full sun on a slope. There are a couple of firs, a walnut, and an alder already there. I can either divide the existing clump bamboo and/or get more, or I'm toying with a running bamboo. I could give it quite a bit of room to form a presence and thought I could control the perimeter by brush hogging it regularly. Will mowing keep it in check? Who has running bamboo and is it really as awful as some folks say?
