Hi! I have a friend here in MA that has a small fig tree he has successfully overwintered in a pot. It has broken dormancy and now has leaves and green stems growing. I know it is still to cold to leave it out overnight here but when the time comes can he put it out directly in to the south facing sun? or will he have to ease it into direct sunlight somewhat at a time? Can he put it in a southern sunny window now?
When he moves it outside he'll need to adjust it gradually to the increased light level. The light indoors even if it's in a bright window is much less intense than the sun outside. Once the weather's warm enough, I'd move it outside into a shady location, then gradually introduce a little bit of sun and keep gradually increasing the amt of sun until it's spending the whole day in whatever location he wants it in.
I have two fig trees that I have been growing in 18 gallon containers for about two years. I only got a few figs off of one tree last year. This January I planted one in the ground. It is amazing how well the tree in ground is doing compared to the one still in a container. I plan on putting the other tree in the ground as soon as I can. I had been told that fig trees should be planted in the ground but I had to see it for myself.
