I posted my very simple method in the other thread just started about cuttings. Is it Too Early to Root Fig Cuttings? - #8 by zendog
Basically, I wrap the top 1/3 in parafilm to keep them from drying out and put them in pots with the unwrapped part all below soil, keeping it lightly moist. I use ProMix, since I like a mix without any added ferts. If you just want another tree or two, you can also just put them in ziplock in the fridge until late March, then wrap the tops in parafilm and stick them in the ground then. I’ve done that in some open space in raised beds and had almost all take that way as well. There seem to be a lot of very complicated approaches, but for most common figs that hasn’t been necessary in my experience.
