This plant has many runners dangling off the main plant
I chose this runner because it has many leaves.
Cut the runner off the plant about an inch above the crown of baby plant.
Fill the jar with water and place plant so that the bottom of plant crown is barely getting wet. Too deep and it will rot. Sometimes I tape a leaf to the jar to hold the plant in place.
This is my cutting after only 2 days! You can see white roots already coming out of the bottom of the plant. When there are at least 4 roots that are 2 inches long you are ready to plant the cutting
