i make rock ornaments by wrapping various size rocks with bailing wire and then i leave 4 to 14 inches of wire left attached to the rocks .i can put the rock on top of the soil and snake the wire up to branch i want to manipulate, and just use the weight of the rocket bring the branch down. some of my rock ornaments are very small so i can hang on a branch , to expose the center of the plant to more light. this is much easier than a bonsai tree approach, of wrapping the branch with wire. you can place the rock ornament in the morning and then remove at nite and move it to a new branch, you don't need to leave it for a prolonged period of time.
