Tree recommendation please!
I am wondering if you can help me with this. My backyard is about 45' wide and 40' deep, and it faces south so it gets plenty of sunshine. Though it's not that big, I am trying to put in some trees there for privacy as it is surrounded by other properties. Anyway, at the far end of the yard, I would like to have some trees that would provide both privacy and winter interest. The landscapers that I am working with suggested that in one corner, I put in a Colorado Spruce, and then at the other corner, a Bakerii spruce. Then somewhere in the middle, they suggested a Mountain Pine.
Would these guys be too big for that space? Also, would it look nicer to have a deciduous tree in the middle? If so, what would you suggest?
I also read that Mountain Pines have beetle problems in Alberta - is that true please?
Thank you so much for your advice!
