We live in Dunbar and want to move and store a dwarf japanese maple for about 7-9 months. We have neighbours who will allow us to put it into their garden for the time being. How do we uproot this lovely ornamental maple and keep it safe. It's about 20 years old, about 2 feet tall with wide branches holding crimson leaves. The trunk is about 3 inches in diameter. Do these plants have a wide or deep root? What do we need to be careful about. We would appreciate any help available. Thank you. Marion.
