Hello, I hope that I'm posting this in the right place. I'm not a gardener, this is actually my first attempt at growing/planting anything.
I live in New York City and my apartment has a small courtyard with built in planters along the walls. The courtyard is surrounded by tall buildings, so it only receives direct sunlight at most 2 hours in the summer. I planted some arborvitaes in August of 2011 and they were doing fine up until about a month ago when some of the branches and leaves began to turn brown and fall off. Attached are some pics. I would appreciate any suggestions/help that there might be out there. Are they beyond help? The middle tree is in the worst shape.
If they are beyond saving, do you have any other suggestions of something to grow? I'd like something large enough to block the windows, but also I'm on a budget.
