Question
I have about a 5.5ft blue spruce in the front of my house and has grown to almost completely cover the front window.  Is there any way we can top the tree and then shape it to make it look more appealing from the curb?  

Answer
It will create a bush, not a tree. The leader is something that provides the vertical growth to the tree, and when it is removed or cut back without any other action taken, the tree will become shrub-form.

IF you do then prune back anything that is distracting from the uniformity desired. Always cut back to where needles exist on the branches. Never cut back to a bare branch. IF you do not want the tree look but more of a bush then the heavy pruning will give you the results.
