i actually fimmed them and Lst'd them. my Lst tech. is simple. i take a rock and wrap it with a piece of bailing wire. i make a rock xmas tree ornament basically, with a good length of wire left attached to it. i put the rock on the soil snake the wire up to where the branch is i want to manipulate, bend the wire over the branch. let it set for a day or two and remove and you can reuse on another branch. you can decorate them too
