This is my step-by-step process of propagating camellia cuttings. The same method works for roses, gardenia, azalea and other woody broadleafed shrubs.
mix propagation media: 1 to 1 potting soil and perlite
Cut a two liter soda bottle in half; make holes in bottom for drainage; fill with media
cut a fresh limb from the shrub
make several 4″ cuttings from the limb
remove lower leaves, leaving only two at the tip
dip end of each cutting into rooting hormone powder
stick cuttings into media
put top onto rooting chamber and secure with tape; put in a bright but shaded spot for three months
Wait until you see a bud form at the tip
gently remove cuttings and plant into individual 8″ pots; fertilize; do not transplant into garden until the pot is filled with roots (note that the bottom cutting did not make roots and has no tip bud)
