Q.Pruning fig tree saplings from roots in springtime
My young tree has all died over the winter except that tons of shoots are coming from the roots and 1 branch at the base. Should I pull off some or most of these shoots so the tree can put more energy into the rest?

Most figs are not hardy in your area, and will die back completely each year, which means that it will not produce fruit without protection. You may look into planting into a large container to bring in and out of a greenhouse for the winter, or mulching extra heavily in the winter.
Alternatively, you can purchase a hardy fig, that is more suited for colder climates.
To answer the question at hand... Pruning to only one shoot each year will make for an easier to control, more attractive, single trunk tree.
