Arborvitae Green Giant
I am considering purchasing some Arborvitae - for the specific purpose of screening. I am considering the fast growing Green Giant. My question is whether they will survive in my Zone 4. Most sites I have found them on say Zone 5-7. I haven't noticed these trees in our surrounding area but I only just started looking. Does anyone have any experience growing this specific arborvitae in less than a Zone 5?
