I'm in USDA zone 6b bordering on 6a in Ohio.
I've looked at lines of sight for my house and concluded that a few privacy plants would be good, if possible.
Some of the new plants should be narrow or able to be trimmed that way. I would plant them near a neighbor's driveway (hopefully with their permission, but not strictly required). I don't want plants spilling into their driveway, or to need to trim them constantly to avoid that. I also am looking for low maintenance or medium maintenence.
I'm looking for plants that are about 3-5 feet wide to block my window view of my neighbor, but not so wide that it takes up the whole side yard. This would be for a second floor window so it would ideally be 20 feet tall. "Columnar" or "Fastigiate" seems to be an attribute to look for.
I guess I'm looking for it to reach 15 feet within 10 years.
I asked some AI assistants and they told me:
- blue arrow juniper (a bit narrow at 2 feet)
- Hetzi Columnar Juniper
My backyard will have green giant arborvitas because there's no space concern.
Seeds and whatnot are another thought. If I'm covering my neighbor's car with seeds that's another thing to consider.
The east yard has the tightest space concern, about 9 feet from the heat pump to my neighbor's driveway. And the first 3 feet are not mine. Heat pumps are like AC; you want to keep the area around the fan clear for maximum efficiency. 11 feet from driveway to the left side outcropping with the window I'm blocking.
Sun is decent in the east. 20-30 feet between the houses, and a lot of tall trees in the area, but still pretty sunny.
There would be probably one plant at A, B, or C; and another narrow plant at D.
West has enough space where it's not a big issue. Similar sun conditions.
F, G, H would all probably be their own narrow plant. Or put one plant at the midpoint of F and G.
H is towards the front of the driveway so narrowness (maybe 6 foot max, ideally ~4 feet) is a larger concern.
TLDR: I want a 15 foot+ tall evergreen plant that is 4 ft wide.
