I have a 2 acre lot that is basically open on all sides and very few trees. There is a driveway that runs between me and one of the neighbors which leads to another home behind me that can be seen from my back deck. There is no privacy any where in my yard. We will be planting some trees in the back that will help "block" the neighbors but I would like to create a privacy "fence" on the one side of the house using evergreen hedges. The area where the hedges would be planted is in full sun. I am looking for something that would be around 10ft at full maturity and very dense. Any suggestions?
