Hello, I am looking for some guidance on transplanting a few arborvitae's for a customer of mine? They are about 5 feet high and he wants to transplant them from back to front. Here are my questions? What size root ball should I dig?. Do I need to burlap or wire basket them? What size hole to put them into? Should I add any amendments (topsoil, leafgro, ROOTS, etc.)? How much time per tree will this take me? Any other advice. Thanks for any help!
