Ciao, No, you should be fine, will you be able to water at all in the winter months to come? My figs are still outside and the soil is saturated with the snow and rain, I will bring them in this way.  They may dry out in a couple months then I just throw an occassional cup of water during winter, just to keep it not saturated but enough to have something during winter.  Are you planning to water any more at all this winter? 

Thanks Maggie.
Based on my previous two years experience, I do not need to water during the winter. The cold storage is cold with whatever humidity it can hold, there are no leaves for transpiration so the soil stays fairly moist till the end of the winter and not crumbly. I was thinking of leaving it in the garage for a week after watering so it will be well drained before going to its resting place which stays between 48F~44F during the winter.

I water once a month. Instead of saying no to watering, I say it depends. I pick up my pots and check the weight to see if they need water. This is much safer than saying dont water. I lost a tree last season not watering. Luckily, it was only a italian honey not a Vasilika Sika or another neat variety.

BTW, as habit I give a light watering once a month in our dry climate.

No watering after storage meant only for my specific situation where the cold room is always closed, good humidity, average 46F temperature, always condensation on the ceiling which becomes ice during late December to beginning of March. Nothing dries up there. That is why I ask the question if I should soak and well drain before storing. Also it is 8.5' x 3' narrow all-around concrete room and stuffed with fig plants like a crowded chicken coup and no access to watering beyond the first half of the length that is why I am pleased that none of the pots needed watering during the last two winters. Before that it was cold storage for veges and other food for the family.

Also, today I removed all the unripe figs and am going to try boiling it in the syrup (Bass, Dan's suggestions). Please don't ask me how it tasted because I will never say it did not taste good. I am not sure if it is a bad or good habit but I have this habit.

I water my figs twice when they were kept indoors. Once should do in my unheated garage. I  probably won't water them especially if they are in 5 gal or bigger pots. The smaller pots I would check how heavy they are.
Note - prior to taking the fig indoors they all had a good fall drench.

Ottawan,
i dont see a problem as long as evaporation is like you stated. If soil gets really dry then in spring there is a chance you lose part or all of your plant. If soil goes completely dry chance increases greatly of having a plant that will be brittle dry and snap to the touch and not make it back.
