I've succeeded in taking a cutting from a winter-flowering honeysuckle (turns out to be a shrub, not a climber, and I'd planted it under a trellis ) by chopping off a 2-foot section, stripping the outer bark from the bottom few inches and stabbing it a foot deep into the soil behind the compost heap. It was a spur-of-the-moment thing. I was actually trying to disentangle the plant so I could relocate it.
Also successful: Late Dutch growing up the fence, two pieces cut off, dunked in water to make sure they were fully loaded and not going to dry out too quickly and then shoved into a pot of compost. I added a little tray of water and five bits of cane around the outside, put a clear plastic bag over them and taped it into place, cut a tiny hole in the bag, shoved a drinking straw through so it dangled over the water dish and blew through it twice a day to keep their air warm, moist and full of CO2. This ... may be considered excessive but ... worked.
Also successful: same Late Dutch, "air layered." I can't remember now whether I bothered notching the stem, but the idea of that is to leave half the stem hanging from the top part, which is still attached to the bottom part by the other half of the stem. The dangling part tries to repair itself and, being attached at the top and in soil, assumes it's supposed to be a root. Slightly awkward to set up, this involved putting a film tube (sandwich bag with the bottom cut off) over the notch site, supporting the stem with a cane above and below the notch site, taping the bottom of the tube closed to make a bag, filling the bag with compost and taping the top too. Given time to get over the WEIRD things you are doing to it and make the most of its new situation, honeysuckle will fill that bag with roots and take advantage of the compost. You can then remove the cane, cut the stem below the bag, dunk it in a bucket of water to stop it drying out, unwrap it and transfer it into a pot of hole full of compost.
