Rhodies should be easy to move, fibrous root systems. Measure the stem or trunk diameter about 6" above the soil line. Figure a root ball diameter of 12" per inch of measure of trunk. If you trunk diameter is two inches your root ball would be 24" across. Take measurements and dig a narrow trench around each plant, 2/3 as deep as the diameter of your root ball. Sever the remaining roots, under the plant and place the root ball on a burlap or sheet to enable you to handle it. Try to keep as much soil intact as possible. Drag it or preferably lift it onto a wheeled contraption and transport it to it's new site. If you can't plant it immediately you should wrap the ball with the fabric, put the plant in a sheltered area and spray water on it frequently. You should prepare a new planting hole after you have taken measurements and before you have dug the plants. Transplant at the same depth or slightly higher, water very well and mulch. Keep an eye on them and water regularly until established. Possibly two years. Same may go for the unknown evergreen shrubs. If your plant is not but an inch or two in caliper I wouldn't even bother digging a narrow trench, I would simply dig with the edge of the spade. Get as much root and soil intact and transplant in a timely fashion.
