Walk to the outermost reach of the azalea branches, called the dripline. Leave a line of flour or spray a line with outdoor safe marking spray in a circle all the way around the plant. Measure the diameter of the circle with a tape measure. Cut a square of burlap to this size.
Dig down into the ground 1 foot deep all the way around the azalea on your marked dripline. This trench doesn’t have to be wide, but the depth is important.
Push the blade of the shovel from the 1-foot depth toward the base of the azalea to slice the soil toward the plant and slightly downward. Do this all the way around the plant to form a wide cone of soil under the plant. Continue until the azalea can be rocked back and forth.
Knock off excess dirt from around the base of the plant, working from the outermost portions of the cone inward until you reach the roots.
Roll up the square of burlap halfway. Have one person tilt the azalea away from you and hold it in place. Stuff the rolled portion of the burlap under the plant as far as possible. Tilt the azalea in the opposite direction and unroll the burlap so the square is under the plant.
Bring the corners of the burlap together near the base of the azalea. Tie the corners together as tightly as possible to secure the roots. Lift the azalea from the hole by grabbing the burlap. Don’t grab the stem or limbs of the plant to lift.
