Japonica Boxwood Turning Brown but Not Dieing

I have 30 japonica boxwoods in a hedge that are turning a lite to medium to brown color. They don't appear to be dieing as on close examination of the leaves they are still moist, fleshy and alive. The brown color is primary and is mixed with some dark green. The extreme edges of the leaves are yellow. From a distance the plants look completely dead and brown. The condition is spreading from plant to plant (about 22 plants currently effected). I am in Sunset zone 18 which can get as low as the low 20's high teens about 2-4 nights/year on average. We have had about 7 - 10 days of upper to mid 20's nights already this winter.

Is this a dormant phase of the plant or could something else be the cause.

Hello Mark75. Buxus microphylla japonica (Japanese boxwood) is known
for its brown, poor winter appearance in cold winter areas. This is normal.
As far as the spreading issue is concerned, I think that the hedge started to brown
in the coldest, most open area, then moved to other areas. This is just the way
the plant is and we have to deal with it. If you lived closer to the coast you probably
wouldn’t see as much brown. Good luck and take care.

Hort, this is at least the second forum mark asked the same word for word question, in.

I expect he got his answer more than a week ago.
