‘Nature finds a way’ Jurassic Park

This spring I decided to landscaping the back yard. I cut a young oaks to bring more light into the yard. I am reusing it in the landscaping as hand rails and posts. I was moving quickly so I opted to just drop them in a hole and pack in rocks instead of using concrete. Well the branches and trunks are growing, I don’t know what’s happening under ground, but parts above ground are sprouting and the whole thing looks very surreal.
