I just purchased a new property in Las Vegas a few weeks ago and I am trying to figure out the best way to block the neighbor on one side. As you can see the neighbors upstairs balcony looks right over into my property and the main area that I want blocked has my grill area in the way of planting bushes or trees. Is it possible to attach or put planters on top of the wall that could support bushes that will grow large enough to block out the neighbor? If so what kind of bushes would grow in the hot, dry Nevada climate and what kind of planters could I attach? I have also considered possibly planting trees on each side of the grill maybe? Any ideas would be greatly appreciated! Thank you!
