I propagate azalea in a soil made up of one part sand, and one part peat. I wet soil and use a pencil to drill a hole for the terminal twig I use. Remove all but the terminal leaves-buds. Dust the stem with rooting hormone and put in their soil.
Your pot should be tightly tented and set out of direct sunlight.
FWIW I use two large peanut butter jars. I cut the tops down to a ring, and glue the two together. making a siamese twin shaped terrarium. Drill holes in the bottoms of both jars to admit and exit of water.
This will hold 12-15 twigs, which is as many as I wanna get done at one time.
