Answer: Some varieties of boxwood normally "bronze" during the winter but based on your description it could also be that the plants have dried out and/or died. If they are still alive, you might try making a windbreak and apply an antidessicant spray according to the label instructions. Also be sure that the soil is moist (but not soggy) and apply several inches of organic mulch over the root zones. It is usually better to plant broad leafed evergreens in the spring to reduce the risk of water stress during the late fall and winter while their roots are not yet established.
