Any thoughts on pruning needled evergreens in winter? I've always told customers the best time to prune evergreens is spring to mid summer to avoid spurring new growth that would likely be injured by cold temps in the winter if not given the opportunity to harden off. I hadn't really thought about what might happen if pruned during the winter, though. I got a call from one of my customers the other day that wants to top a row of "pines" ('cause they have needles, they must be pines! but if I remember correctly they are spruce or possibly balsams). I figured since I'm so busy right now, with all the snow we've been getting in the NE and all, I could certainly tackle this project with him now, but not at the expense of the trees health.
