I have 260 feet of fence line that I want to put a dense tree hedge or tight
tree line. I know I can't get any evergreens because I want a 30 foot
minimum tree height. So what would be a good tree and how far would I have
to space them. Something that is fast growing and doesn't require a lot of
water and turns pretty colors in the fall. I was thinking about Chinese
Pistachio . Any other ideas?
