How about spruce trees at a height of 6 to 8 feet - not 10 to 14 feet.

What would be the cost per tree?

Also, how many inches would they grow per year in Zone 5 with partial to
full sun?

Many thanks,

New York State has an excellent land grant University called Cornell.
Search for the Cornell Cooperative Extension in your county and they
can tell you exactly what to plant, how and when. �A good wind break
should be made up of several species, spaced properly so if any fail
you won't have huge gaping holes in the screen. �Do not be tempted to
use fast growing trees of any kind and seek the moderate growers. Much
stronger. �Also look for your local chapter of the Native Plant
Society in your region.

Had you read the original post carefully you'd note that the OP is
only wanting to plant 4-6 trees, for *privacy*, not a hedgerow/
windbreak as one would want for seperating farmland acreage/pastures.
With only 4-6 trees desired it should be obvious that there isn't
space to plant what you suggest... and he'd like to live long enough
to see his trees grow... often reality and practicality usurps theory.

I happen to live in the same area as the OP, I know from my own
personal experience that for an *all year* privacy screen in this
locale no other tree will do the job nearly as well as the Norway
spruce. Mixed evergreens don't do well, and deciduous trees offer
little to no privacy and in time will likely kill off the evergreens.
For a privacy screen I would definitely chose all one type of spruce;
Norway and Colorado cannot coexist in close proximity, in less than
ten yers the Colorado spruce will become smothered to death. Of the
two Norway is heartier and faster growing, it also will achieve twice
the size, so if there is a space limitation I would then go with the
Colorado. I'm sure there are other choices but as is often the case
with usenet long eddy appears to be gone, so there is no way to
discuss details regarding his property.
