TRANSPLANTING-NANDINA AND AZALEAS
DESIRE TO DIVIDE AND TRANSPLANT LARGE PLANTING OF NANDINA AND SEVERAL LARGE 40 YEAR OLD AZALEAS. ALL HEALTHY .PLEASE ADVISE FEASIBILITY ,TIMING AND ANY PERTINENT ADVISE,TRANSPLANTS,PRUNING ETC.ETC.
The best timing for transplanting shrubs is late winter, but wait until the ground is not frozen or terribly wet.
You can't divide these shrubs per se, unless there has been a branch that was in good contact with the soil and has grown roots of its own. If you find a branch like that, you can slice it away from the parent plant and treat it as a separate specimen.
You can absolutely move them though, as azaleas in particular have shallow roots.
We'd suggest preparing the planting holes where they will be relocated before you begin digging, so that they are out of the ground and roots moist until for the least amount of time.
Be sure the new site is right for the plant's needs.
Take a look at this page for helpful info, including links to after care:

THANK YOU FOR YOUR GREAT RESPONSE ONE POINT I NEED ADVISE ON,THE AZALEAS IN
QUESTION ARE HUGE CAN THEY BE PRUNED DURING THIS EFFORT AND IF SO HOW AND HOW MUCH ? ORIGINAL QUESTION # 543996. THANKS
Yes, you can prune, as much as you need to to make them moveable for you.
Take as big (wide) of a rootball as you can and keep them watered (in good draining soil) throughout the first year and a half.
