I have 6 blue spruce topiaries. When I prune them with my electric trimmer they turn brown where they were cut. How can I stop this from happening?

Sounds like the blades are bruising the tissues. I'd either have the blades sharpened or prune them with hand pruners (they generally remain sharp for a long, long time).
