  • Hydrangeas prefer mild temperatures. In areas with severe winters, dieback (a plant that dies from the tips of its leaves inside) can be a problem if it is not protected.

 An area facing north or east, where temperatures remain constant, is a better option than the area south and west of your area, which will heat up in the winter sun and cause shoots to open prematurely and be vulnerable.
