Guess I agree with BLB. Here are a few related comments:
1. (worry about not producing figs?) -- I wouldn't worry about trees not producing fruit in the first year. They need to grow. Any energy they put into making figs takes energy away from growing.2. (let them grow?) -- I'd let them grow unchecked. But pinch a stem if you want to force branching. (Just don't pinch it too early... it needs to grow). Early on (first few years) is a good time to be thinking about the shape you want for the tree. But again, they need to get some size... I'd let 'em grow. You can prune next year if you've got a weird shape.
3. (remove the figs this year?) -- Some members say remove them all, some say you don't need to if it's just a couple of figs (or to take off all but a couple). I guess I don't, but it depends on how well the tree is growing... if it's stunted, then remove some (or all). Also, if you eat one of those figs, be aware that the taste of the fig will change (generally improve) as the tree matures.
4. Up to you I guess... I'd probably leave them in gallons this year, and up-pot them in the spring (or else when they are fully dormant in the winter). One additional consideration is where you'll overwinter them in the first year... you'll want it to be cool enough to let the tree stay dormant, but not so cold that they die back from a hard freeze. (A young tree is more susceptible to die-back than a mature tree with more established roots, so you'll want some protection this year). The point I was leading up to: a bigger pot / more soil generally speaking provides more protection than a smaller pot / less soil, at least if those really cold spells in 6a are of short duration. The bigger soil mass is a bigger heat sink, so the temperature around the roots won't vary quite as quickly. So, where are you keeping them for the winter? A cool-but-heated garage or basement? Or a shed / unheated garage, where the winter temps are just like outside? For me, I'd up-pot them when dormant (multiple benefits, including helping the trees to mature more fully as you await their move to in-ground).
Just my 2 cents. Good luck with your new trees!
