Just as the title says, I am about to purchase 2 japanese maples. I have found the cultivar I am interested in locally available as a ball and burlap tree- listed as 60" in size. Not sure how large of a tree that is. I hope to see them in person later this week. I have also found the cultivar available from an online retailer as a field grown tree in a root pouch container. This tree was said to be between 4 and 5 ft or 1 1/4 diameter minimum. I am in the northeast and will be planting the trees about 1 1/2-2 months prior to ground freeze if that matters. I'm just looking for the opinions of the professionals here on which tree they would more prefer to purchase and plant if given the option. Thank you very much in advance!
