I’ve had some success with hormone powder, and also with liquid rooting solution. (I picked up a whole gallon of the stuff on clearance, a few years ago.)
Some plants have optimum points to make the cutting, and maybe even angles. Generally remove maybe 3/4 of the leaves and keep humidity high. One can use a bag, or I’ve used 2 liter soda bottles with the bottom cut out, and the cap loose (in winter) or removed if ambient humidity is higher. I’ve also used my tallest soda bottle “pots” inverted. (I’ve punched small holes in the bottom for use as pots.)
My starter “pot” is often a plastic drink cup found in the ditch*, which fits inside the soda bottle. Then when the plant has rooted and is (hopefully!) doing well, I transplant it into an intermediate size pot: I flip the soda bottle become a “cover” into a soda bottle “pot”.
*Which reminds me I need to “walk” the road that heads out to the East of this place: I’d walked out there yesterday to check downed branches and a downed road “curve” sign — It’s in pretty badly bashed up shape including a now “L” shaped post, and was carried ~ 25 feet from where it had been “planted”. In the process I found a LOT of new trash, about half of it discarded “Wendy’s” cups and so on, apparently from last weekend / mobile partygoers / lowlifes**. So, I need to go out there with at least a 13 gallon bag to do more pickup.

**These litterers need to be sentenced to a hefty fine and a week of picking up road trash on REALLY hot, humid, summer days. I did that sort of work for a few days in my late teens for the Youth Conservation Corps: Believe me, it cured any such tendencies in the kids in our work detail!
(Well, we also painted woodwork @ Garden of the Gods, swam @ Pounds Hollow Lake, cleared new trails, canoed @ Current River, had terrific cooks (the gals complained about the weight they were putting on!), learned a LOT (and some great stories) from the National Forest Rangers, ...a certain girl..., and had many fab adventures and times. Terrific memories...! A few minutes to half hour picking up roadside trash always brings them back, so, it’s certainly not the worst chore in the world. :-)
Thanks
