Yes. I think owning versus renting/tenanting/being housed may have a lot to do with this. Why go the the effort of planting trees and spending your time on your landlords garden.
This is exactly why yard service is included with my rental home. I want to know my yard is being taken care of. However, in the 13 years I've been a home owner... I've never planted a tree. I actually had one removed during a backyard makeover.
