All plants are vulnerable to winter drought but new plants, especially evergreens, are extra susceptible and we are heading into winter well below normal rainfall for this time of year.  For example a 3 gallon boxwood needs approximately 3 gallons of water a month.  It would require rain for 3/4 of a day slow a steady for our boxwood to get what it needed.  The easiest method is a 5 gallon bucket with 8-10 nail holes in it, fill with your hose to the appropriate level and it will drain out before it can freeze. Don’t forget to drain and store your hose properly.
