I have a lot of spruce for the size of my collection. Young healthy ones are pretty sturdy, but older and more stressed ones are very sensitive to the timing and extent of the work done on them. As a general rule, mine have not responded well to styling, collecting or repotting when in active growth. I believe these things are best done in early spring. Styling has worked for me in late summer or fall, but I wouldn't repot then.
