planted a birch in northern MN
I just planted a birch in northern MN. The leaves are turning yellow. What's up? Too much water or not enough? Not sure why the leaves are turning yellow and falling off.

Newly planted trees need lots of water. Daily for the first few weeks, and more if the is dry and warm.
If the tree has received to much water, due to rainfall, there is little to do except hope the roots can dry out.
Yellowing leaves is generally a sign of watering issues. The tree is also most likely stressed from the planting.
Here is a link about new tree care.
