Lucky you to have such a lovely well producing fig tree. I love figs and bought a fig seedling to see if I could grow it in a container here in Canada - zone 3 garden. I thought I would have to take it outside for the summer then bring it in to the sunroom for the winter - totally not necessary! My fig tree which has grown to quite a size now and loaded with figs (although much smaller than yours) starts to produce figs in February when the light starts to return so I just keep it in my sun room all year round (I had transplanted it into a large and heavy clay pot so I don't think I would be able to move it in and out.) I'm thinking I might try a larger fruiting size variety since I'm growing it indoors. It sounds like the Kadota might be a good variety to try.
