I agree with the poster that said not to plant the trees on the property line. We did that. We bought about 32- Leyland Cypress trees and planted them along the property line of a nasty neighbor that didn’t like our horses. As luck would have it…the neighbor moved about 3-years ago…long before the trees could block her view!
The trees are HUGE now!! Lovely to look at. But, the horses do ‘trim’ them…at least one of them does. We have a 3-board oak fence in between the horses and the trees and the neighbor had a split rail fence on their side of the trees.
you could put a couple strands of electric in between your new trees and the horses…just a thought.
The problem with trying to get ‘rid’ of the view of the neighbor is that it takes a while for the trees to grow. You probably would be better off planting the groups of trees in the areas where they would just block the ‘junk’ on their property and it sure wouldn’t cost a much as planting an entire property line does…sigh. [Bradford pear trees are great blockers…one nice tree per ‘junky spot’]
Oh…our other neighbor had pine trees all along our other property line…a bug got into the trees and killed most of them…he cut them all down and now, everytime we got outside, it’s come stand at the fenceline and talk a while…sigh. We’re certainly NOT going to plant that fenceline in cypress trees…but, perhaps a privacy fence in our backyard would be ‘easier’.
Feeling your pain…Best of luck!!
Take care.
