My mother used to use rooting hormone to propagate her roses, and she always got them to root. I just used rooting hormone for the first time this past month. My observations are: On a couple of varieties of fig, I saw roots emerging in about a week, while others took a couple of weeks; the hormone seems to scarify the bark of the cutting and roots developed vertically; not absolutely certain whether it increased the percentage of the cuttings that rooted successfully. The reason I'm not certain is because I also used a heat mat and humidity dome this time. Changed more than one variable, so I can't be absolutely certain which had the greatest effect.
