I myself like using a root hormone powder... And brand is good. U just dip the bottom of branch in water about 1/4 or the branch & then dip in hormone. You can tap the bottom a little on top of hormone can to drop back any extra. Then I like to soak my soil in the container I'm going to use pretty good, make a hole in the center with my pointer finger, then put the bottom part in with medicine about 1 inch or 2 and slowly smash the dirty back towards the bottom of plant with out dropping medicine from plant. I would use a spray bottle to spray water on top of dirty just to keep moist. You do not wanna water it much cuz the medicine will come off. I hope that helps. Ofcourse unless you have a green thumb like myself that everything to cut & burry just come up! Lol I was blessed by mo grandmother & mother that had green thumbs.
These are all so called Yellow Bells here in Al. to root them just did a hole about 6 inchs long and 3 inch deep and lay them in and cover then water ever day for about a week and there they are, so ez, good luck
