When you bring a fig tree inside for one day, you lose the photosynthesis that could have happened. Also, presumably the leaves lose some of their tolerance for wind/light/etc. I think that if it is just one day, there is no serious harm. But if it was a month, there would be a lot of harm.
In general, does anyone have an idea of about how many days indoors it takes before it starts to have a significant negative effect on the tree? We're all trying to manage this situation of should I or shouldn't I bring the tree in. We're asking what is the temperature at which damage starts to occur, which is a useful discussion. But the flipside to me is how many days indoors before bad things start to happen.
Specifically, I have about 5 trees that are actively growing now in full leaf, because I had them under lights inside for the whole winter. I went through the process of gradually acclimating them to outdoor conditions already, because of how warm it has been. So until yesterday, they were happy outside (I brought them in some nights). But yesterday, with temperatures at 45 degrees with 30 mph winds, and today, with it being 35 degrees when I left for work, they have been indoors. I am worried about them needing to be re-acclimated to outdoor conditions if I leave them inside for too many more days.
Thoughts?
