Evangeline....Stand 4 of your treated cuttings upright in a pot and fill with soil. Water thoroughly and place a 2 liter bottle with the bottom cut off over the cuttings. Keep the fig cuttings warm but not in direct sun (bright window). Don't water unless the soil becomes dry. Take a look at internet through Google.
I would talk to my local County Extension Office and see if their perspectives are any different.
It is easier than you think!
I have 3 in my yard, all free courtesy of local wildlife. When they popped up, I dug them out and placed in pots in a protected area until they were big enough to be replanted in ground.
