According to the Iowa Department of Natural Resources, it's time to stop pruning oaks in the Midwest where the weather has been abnormally warm.

Typically, it is suggested that pruning can occur through March.  This year, not surprisingly, is a little different.  The primary cause for concern is oak wilt, a fungal disease that is easily introduced through wounds to the tree during the growing season.  Oak wilt is typically fatal to the tree within the growing year.
