Greetings Karen:
I'm of the opinion that you should move the planting location just a little bit from the uprooted tree site as the uprooted tree likely has displaced a significant amount of top soil (O, A, and upper B horizons). Rather than planting a new tree in a depression (i.e., pit), I certainly believe the tree would benefit more from a suitable, adjacent planting location that does not have pit/mound characteristics.
Just my opinion...
