Eveth, I tried every way possible to propagate Fiddle Leaf Ficus, and trying to root cuttings, and those cuttings have to be from fairly mature branch cuttings (which yours is not), had a success rate of perhaps 25%. The only way I found to increase that rooting success rate was to air-layer branches. That was a productive way to propagate my "mother" fiddle.
Still, try to root it and let's see what happens. Just because I had little success doesn't mean that you won't be successful. I love experiments!
