What do you use to plant cuttings from rubber tree plants

You can use jsut about anything as far as potting soils go. They are, generally, pretty tolerant. I make my own rooting hormone. It is a spoonful of honey, a rushed aspirin tab, and just enough drops of water to mix it all into a paste. Apply this to the cut base of the stem and put into slightly moist soil that stays slightly moist. Alternately you can air layer the plant, and grow roots while it is still attached to the plant. Then you can cut off and plant it. Here is an article about propagating them: https://www.gardeningknowhow.com/houseplants/rubber-tree/propagation-rubber-tree-plant.htm
