I need help. I live on a corner .40 acre lot and due to zoning requirements, i cannot have a full size fence so we have a 4 foot high white vinyl fence. however, you can see directly into our backyard from the sidewalk & side street. I am considering planting a row of the thuja Steeplechase along the side of the fence as well as in front of the fence parellel to the front of the house. I am worried at their eventual size. I do not want them to grow so large that we will need to rip them out in 10 years. Does anyone any advice on how large they will get, I have read anywhere from 25 to 50 feet.
I think that 25 feet would probably be okay, because that would be about the same height as the house, but if they grow too much taller i am afraid that it will be overkill for a .40 acre lot in a neighborhood with sidewalks, etc. I would like something that grows quick (at least to 10 feet)and is narrow. Are there any smaller alternatives to the Thuja Steeplechase? I live in New Jersey. Any help would be greatly appreciated.
