pruning weeping spruce

Question

We purchased a weeping spruce about 4 yrs. ago and it suddenly began to grow much bigger and the branches no longer weep. It looks really out of place and I need to get it back to it’s original unique look. How do I prune it and get the branches to weep?

Answer 1

Is that a graft union I see in the first photo? It's possible the straight branches are from the rootstalk and are taking over. All suckers from below the graft should be removed as soon as they are noticed.

If the bottom weeping half is how it is supposed to look, you can prune out all the straight branches back to the collar.
If that isn't how it is supposed to look, the top may have died when the rootstalk took over.
