How do you plant a new tree? Most people know to dig a hole “twice as wide and deep as the root ball” (according to the label I found hanging from the branches), then stick in the tree, making sure the roots are well buried.

I’ve come a ways since those early days and even though I still have much to learn, I’m eager to pass on my limited birding skills.
