That sounds like a pretty good plan, as long as the temp in your garage won't drop below 20 degrees farenheit.

Here are a couple of other things to consider in terms of varieties to grow. Black Marseilles VS is supposed to be the sweetest fig that will grow in a cold climate. Also, you might want to consider a variety that produces brebas, like Desert King, because it is more likely to ripen in time in your short summer.

I would sugest ,to get a small greenhouse and start your figs growing early,so they will have enough time to ripe.
In May,you slowelly get it adapted outside,by first placing it in total shade,then in a few weeks moving it toward more sun gradually.
That will work very well for you

HI Nick,
this is my experience growing in containers near chicago for 8 seasons.
When plants are from 1 to 2 seasons old and stored for winter in my attached garage they did get some dieback the following spring some more than others but not severe enough to kill them. After 3 seasons on a few i did get some tips that turned black and had to trim them a bit in spring, each season as plants grew older and a little bigger they did better. Last winter our coldest in the 7th season they saw they suffered no dieback period with temps for several weeks at a time in the mid teens in garage and coldest temp recorded in garage for several days was 8 above zero when our cold spell hit 23 below zero So in short your good for storing them im sure if your garage is insulated good for us its the darn wind that drops garage temp rather quickly when the big overhead door opens so best to close quickly and not leave open when blowing or shoveling snow as some of our neighbors due. In early spring as early as March 15th this year i put them out in full sun on driveway to slowly wake them up as temp was in high 40s i believe. Then of course back in garage at night, by end of March we had snow, early April brought a good snowfall and trees stood in garage but were getting sun thru top panel of overhead door which is glass and temps in garage were slowly riseing as temps outside did the same so they start to wake up. Little by little the brown buds on the trees start to turn green and they go out on driveway more and more as weather permits if not they are inside protected from the damaging winds when they open leaves yet still getting a little light, for the cold winds will damage the leaves and set it back so one has to be carful at this point but i do this each spring and never had a problem.Like Herman posted a greenhouse would be ideal and work nice, my neighbor always says why don't you build one attached to side of garage in your yard as i have the space but inside garage storage works well for me. So perhaps it would for you and you can keep them containers off cold cement and put them on 2x4s like i used to , i just throw old bed sheets over them to keep them in dark during time there doramnt and take them off in late winter.So i think those are your 2 options greenhouse or garage, another but backbreaking is a basement which we do not have.

YES you can grow fig tree and get fruit from it such as hardy chicago , sals and from what i heard the Black Marseilles amongst others. If you have room try for some of the early ripeing types also with the cold hard types to see what happens, im doing this with some new plants this year such as ronde de bordeaux and pastiliere and a few others.One other thing give tree as much sun as possible and if you can put the container on cement or blacktop for extra heat not on grass.
Hope us posters have helped you a litle bit.
