And you thought getting a PHD would take years of hanging around the library when all you needed to do was go outside to dig a hole. For that you DO need a PHD - a Post Hole Digger. Making that hole productive for a new planting does require a bit of art and a science, but there are no early morning classes or exams to sleep through. So get your PHD and start planting! Your landscape will be ready to enjoy by spring break.
