Mix 5ml of Rootex with 5ml of water in a small container.
Dip lower end of cutting into the liquid for 2 seconds
Allow to air dry for 30 seconds and plant in potting mix.
Water the pot and keep potting mix moist until roots appear.
N.B. a plastic bag over the pot and plant will help maintain moisture while roots are setting, but allow some air flow, do not seal it tight.
