Here are pics of my in ground tree.

And it is a????

Has it been through a winter yet or just planted this year?

If it's been through a winter what type of protection did you use? Bury or cover?

I planted it this year. I hope it makes it through the winter.

It is an unknown Black fig. Possibly a Geno's Black

I hope you will wrap it to protect it during the harsh Maine winter!

I grow figs just north of Maine in Nova Scotia. We are close to the water so we have more moderate maritime winters. I do protect my trees by building an insulated "shelter" around and making sure there is a good layer of mulch around the base. Seems to help here. Some of my trees have been in ground for a few years now... and finally starting to produce.

Leaving a young tree in-ground especially in a cold climate is very risky (the wind, the cold, the hungry critters..)

A trick that I find works with younger trees is to plant them in-ground when it warms up (i.e. when you plant your tomatoes ..).  Then in the fall since they are still small dig them up and put them in a container and store in a not too cold garage.   next year repeat ..

This gives you the option of having them in a container to give them an early start in spring (especially if you have a sunroom/greenhouse).  I find the figs I grow this way produce figs much earlier then the ones in-ground permanently. 
When they get too big to haul around I leave them in-ground and cover them appropriately.
