I just built a new home in Rehoboth and for mitigaation puropses I am required to plant nine, 12 foot tall, 3 inch in diameter trees on my property. The property is small. I would like to plant a privacy line so I would like these trees to be narrow evergreens. I do not mind pruning twice a year but would be looking for a tree that is thinner than wider but very dense. Again, I would consider pruning the bottom because we do have a fence. We do have some room, just do not want to use it all up. We get a good amount of afternoon sunlight. Any suggestions of types of trees and sources for buying these trees where they will also deliver and plant? I want to give them the best chance to thrive and want it done right. So far I have been reccomended Centennial Girl Holly, and Bakeri Spruce. I appreciate any advice possible!!
