Good job! Sometimes we get complacent with things such as annoying trees that don't produce fruit sitting there in our yards, just taking up space and blocking sun from our fruit producing trees.
Sometimes we gardeners also get lazy and keep fruit trees that don't produce well or the fruit quality is not good, removing these bad fruit trees and replacing them with better fruit trees can be even more difficult than removing non fruiting trees.
Keep up the great work. I see your yard is messy like mine, I need to motivate myself to clean it up:)
