Pruning in late summer helps the plant get ready for winter.
Keeping the plant watered well into the winter freeze.
Adding 5 to 6 inches of good hardwood mulch around the base of the plants will help insulate the roots.
If the temperatures are well below normal for the Mock Oranges growing zone--4-10, you can cover the shrub with a sheet at night. Remove during the day.
