Thanks for the replies. I'm still considering the LEyland, but am looking at
blue spruce too, but the Blue S's are more expensive.

I am getting conflicting info (as I always do when researching
anything) about the height of the mature "green" Leyland Cypress. I usually
see 40 to 60 on the label on the tree, but yesterday I saw a label indicating
20 to 30, or 30 to 40, for a "green" LC. Actually, 30 to 40 would be
preferable, for me.

As far as environment for my prospective LC's. they would be 8 to 10 feet
apart (getting conflicting advice about how far apart to plant, whether
tree-touching-tree is / is not a problem). They would be in full sun, and would
be screening out a commercial nursery (how ironic, eh ?). The "nursery" land
is used as a dump for the nursery owner's road paving business !! These trees
will shade his property. The only view I will be "ruining" for the other
neighbors will be their view of the dump, and, if the trees grow tall enough,
their view of the horizon above the dump. I and my neighbors are in 3-story
townhomes, so we have a bird's eye view of the dump, at this point.

I heard from a (different) local nursery that a lot of mature LC's were
broken off during last winter here in Pa.

Yes , we have bagworms here too, so that will be a concern.

Decisions, decisions.... leaning towards planting the 40 to 60 ft "green"
Leylands, and watching them grow, hoping for the best.
