Enough space for apple trees?
I'm hoping you can help me determine whether I have enough space in my front yard to plant apple trees and, if so, what varieties you would recommend.
The space I have is about 20 feet by 25 feet. Do I need at least two trees, and is that enough space to fit two? What should I look for to make sure they will stay small enough to fit the space?
(One thing I'm confused about is: If a tree says it should be planted X feet apart, does that mean it also needs that much space between the trunk and the sidewalk?)
Thanks in advance for your help and suggestions.
