Q.Can Western Hemlock Survive Or Thrive In Southern New England?
I live in eastern Massachusetts. Would like to plant Western Hemlock. Would it survive at all? Would it thrive here. I believe I am in zone 6, close to zone 5, about five miles from the coast.

You may want to consider a hemlock that is resistant to the pest Hemlock Woolly Adelgid such as the Chinese hemlock.
