Privacy fence with garden along it. As you can see we have a small narrow back yard but we still planted 8 trees for privacy. Most of my flower beds are in shade and it has taken me awhile to figure out which are the best plants for this challenge.
Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
