Hi there!
I'm looking to create a privacy screen along a section of fence. The length of the area is about 15ft (sketch below). Opposite the section of fence is driveway concrete. What's odd is whoever poured it did it slightly unevenly, which makes the available dirt strip 2 ft on one end and 3.2 ft on the other.
I've been reading into what hedges might be best. The fence is already 6 ft tall, but I'd like probably 3 feet screened above that, so the goal is for the hedge to be at least 9 ft tall. The best I've found so far is Thuja Green Giant and Thuja Emerald Green. Both seem only available at 6 ft max, then grow from there. I'm getting the impression that Emerald Greens grow slow and Green Giants can grow up to 3 ft per year. This makes Green Giants the clear winner in my eyes.
However, I'm also reading that they need 3 feet on all sides. If this is true, I'm going to have to cut the concrete, which I can afford to do but was just curious if this is true and necessary. What are your thoughts/suggestions? Also, how do you best acquire Thuja Green Giants? The best I could find were 6 ft Emerald Greens about an hour from me. Otherwise, I know of fast-growing-trees.com. I'm in hardiness zone 8b/9a.
Thanks!
