Is there a way to boost the growth of this one, ID mix up and lost. It has been a month now since I try to encourage rooting this one. It is the only hope in a bunch of cuttings and suckers acquired this year. I never expected that rooting a fig cutting would be very hard. 

Keep hydration to minimum to prevent rotting, maximize sun exposure if possible. Creating a greenhouse effect by having the pot in a humidity bin while still getting ample light has work for me in getting reluctant twigs to grow out... Good luck...

If there are no roots at all, then you could try scoring the base and dipping it in rooting hormone.  That's the method I use and rarely does it not work.

I haven't watered it, it is still in its damp potting soil and a humidity dome was placed , 
I might transfer it to a more sunny place to provide filtered light though.
