Best time of year to prune spruce trees

What is the best time of year to trim/prune spruce trees? I've read different things from dormant time during the winter to early spring after new growth.

Hello, below are some general guidelines for pruning spruce and other conifers. First of all, we need to define what you're pruning. If you're looking to prune back the ends of the branches to produce a desired shape (shearing), then late spring or early summer in the growing season is best. Dead branches can be pruned off at any time, but if you want to remove whole, live branches then prune from late winter to early spring before new growth starts. When removing the whole branch, be sure to leave the branch collar intact to ensure the pruning wound heals correctly.
Good luck!
