Customer Review
"I usually purchase nursery items from Lowe's/Home Depot, this was my first time purchasing trees online. I bought 6 Green Giant Arborvitae from Nature Hills, which were shipped/delivered very quickly, and arrived in pristine condition/very healthy looking.
Based on my experience with them, I would definitely recommend Nature Hills Nursery.
