Question
i have 2 globe blue spruce which are app 10 yrs of age.  Should I ever prune these and if so hows7

Answer
Hello Francis

Yes, you can prune your globe blue spruce to keep a nice shape.  Just prune the current seasons new growth, back to, but not into, last years growth.

New growth is easy to recognize as it is lighter in color and softer to the touch than the old growth.
