Other than using air-layering methods, I root semi-green, wood cuttings, and I find it to be very easy. Here's what I do:
Find a short 7"-10" length of semi-green wood. I like to use a short branch that recently sprouted so that the cut end of the branch has some harder, semi-lignified, wood near the base end section (where roots will form) and a terminal bud at the outer end. I don't refrigerate these cuttings. I cut off all leaves along the stem but keep just two or three smaller leaves toward the terminal end. I cut the neck end of a large GREEN soda bottle off, right around the top of the label, but I leave the label on the bottle. I melt a few holes into the 5 knobby projections at the base of the soda bottle, for drainage, fill it with some DAMPENED, NOT WET, quick-draining, rooting mix and stick the cutting into the mix that is now filling the prepared, soda bottle. Make sure the stem of your cutting is at least 2/3 buried.
Now, using the same diameter soda bottle, cut off the top, cap-end of a CLEAR bottle but stop where the cut diameter of this neck section will be just slightly less than the full diameter. You will need this smaller diameter, tapered area. You will be inverting this clear bottle and placing it over the top of the cutting. The tapered section will make it easy to slip the clear bottle on top of the green bottle holding the cutting. This whole setup will become a mini-greenhouse for the new cuttings. I also remove the label from the clear bottles so light can reach the leaves that you left on the cutting. So you will have the green bottle holding the cutting on the bottom, and a clear soda bottle on top. You could also melt a few holes into the clear top so moisture and air doesn't stagnate. (Note: It's best to prepare all your bottles in advance).
I put my bottled-up, cuttings in a very bright, and warm, window. Within 6 weeks, roots will be seen through the clear, green bottles. If I think the rooting-medium is getting too dry, I add just a little water. Some varieties will strike roots quicker than others.
Once the roots start filling up the lower bottle, and the terminal buds start showing new growth, I remove the top, clear, bottle for a few hours each day. Eventually, you could gradually expose the rooted cuttings to stronger light, and more fresh air, but no direct sun.
When it comes time to pot up your newly rooted cuttings, gently, with a sharp scissors, cut the knobby bottom sections off the green bottles, being careful not to disturb/cut the new roots. Push, and slip the newly rooted treelets through the bottom of the green bottles and into the new pot...or, simply scissor-cut the green bottle up one side and remove it from around the root ball. Plant the new treelets into pots. When done right you will have a minimum of root disturbance and little, if any set back. Gradually introduce your new trees to full sun.
I have very good success with rooting semi-green wood. It's a good method to use when air-layering is not practical. There are some You-Tube videos featuring Ray Given that show other methods for rooting "green" fig cuttings. If done in early season, you can expect to get some good growth by the time cooler weather starts.

It takes longer to explain this method than to actually do it. Once you prepare your bottles, it's very quick and easy.
