Hi, I live in London Ontario and want to plant a privacy hedge in my backyard. Unfortunately, there is a black walnut tree nearby. I have read that Canadian Hemlock might be a good choice in that it has proven to survive near such trees. Anyone know if this is, indeed a good choice. What are pros cons of Canadian Hemlock and are there any other choices I might consider. Also, where would be the best place to purchase the trees? Thanks, R
