growth depends on lot of things. how much you are feeding it, how often you are up potting it.. what type of fig you are growing. if you go to vince's route as above, you will get better result then keeping it in the container. if you do what i do, you get at most 2' in first yr. more then likely 1'. i keep all my first yr cuttings, well most, in 1 gal container. i give them minimal fertilizer and lime. i do not up pot unless it has to have larger container. most i got out of it was 2'. on the other hand, ones that i moved to larger container.. 4 gal, then to 10 gal grew up to 4-5' in a season.
as to top growth not happening.. some cuttings will do that. i had a cutting that had great roots, but no top for good 4 months. then it put out very small leaf and didn't do much from that for another 5-6 months. this yr, it started to grow and it put on about 1', and still growing. if it wasn't a fig that really wanted, i would have dumped it. but i was looking forward to this one, so kept it and i'm glad i did.
