I filled my potting soil up to the top of my cells to put these cuttings in. The amount of potting soil you put in is just enough to fill the cells without compacting in there but it also has to be enough to where you water it, it tends to settle in there a little bit. We're going to be using our indolebutyric acid is what it is, it's a rooting powder. We're going to put that on the tips of the cut Salvia leucantha cuttings and then we're going to plan them directly into the potting soil just by sticking them in there. These plants are going to need to be kept watered but not terribly wet until they rooted down which it will take several weeks. It needs to be kept out of direct sunlight.
