Hello, We are currently finishing off some landscaping and looking to plant a tree that will offer considerable size for privacy and shade from houses above us. We are also hoping for a fast growing tree. Considering a maple tree, but I'm not up to speed on the root structure of the maple and looking for suggestions. The tree would be planted in the back corner of our property which borders a city eavesment, some free space, and the bottom of a neighbours property. Any advice would be greatly appreciated. Thank you. J
