Can I trim my boxwoods now?
I see that there are 4 days of dry weather and no frost predicted, can I shape up my box hedge? Thanks Corvallis

Hello. The information that I could find recommended not pruning prior to our last frost as cold weather after shearing your boxwood will cause leaves to turn gray. Pruning during hot weather will have the same effect. Based on this I would recommend you hold off pruning until Spring. We can have late freezes later than that, but they are not common. I have listed a couple of extension references from other states. The second one from University of Maryland includes a video showing how to prune boxwoods specifically.
