A plant propagation apparatus and associated methods are disclosed for automating and optimizing the process of cutting, scraping and applying rooting hormone to plant stems. In at least one embodiment, a housing provides an at least one substantially tubular-shaped receiver sized and configured for removably receiving a plant stem therewithin. An at least one blade is positioned within the housing and configured for cutting the plant stem at a desired angle. An at least one pump outlet is positioned within the at least one receiver and configured for selectively administering a volume of rooting hormone to the plant stem. An at least one abrasive surface is positioned within the at least one receiver and configured for scraping an outer surface of the plant stem, as the plant stem is removed from the receiver.
