Hardy, pest-resilient, evergreen shrubs, 10-15' tall
We have 26 hemlock trees that we have to destroy due to the woolly adelgid (we are heartbroken, to say the least). We would like to plant another evergreen privacy 'fence' that is hardy re: wind, sun, pests, and disease and will only grow 10-15' tall,6-8' wide and can grow in a sandy/alkaline soil. I am afraid we are looking for the impossible fix. However, we're hoping for suggestions. Help!!
