Bud swell on Colorado Spruce

My Black Hills and Engelmann have been pushing buds and shoots for weeks now while my Colorados aren’t really swelling yet, is this common for anybody else ?

Where are you located? I live in northwest Washington.
Mine are swelling but have not pushed their new growth.
This the same with a majority of my trees.

I’m in central Illinois

This is normal for our region. I live in Nebraska and only a very small amount of my Colorado buds are just beginning to swell. They usually are the very last of my trees to start. Even my weeping white pine is starting to exhibit really swollen buds. But when it starts to elongate it will grow fairly fast almost catching some of my other pines.
