Blue spruce - trimming, good or bad

[blazer]

I have been asked to trim back a Blue Spruce in a garden about 25 ft high, not too happy with the idea. As I'm not sure how the tree will react - sprout more growth on the tips or die back.

 

If it was my own I would wait untill it got too big and chop it down, or take the risk and cut it back but for somebody else who has no idea about trees, they can get a bit upset - like the Japanese lady did once:blushing:.

 

I was asked by a very polite Japanese lady to cut out the lower branches of an oak tree in the garden, lots of bowing and smiles but in the lack of english and lots of arm waving she really meant the upper braches - she came out of the house like some 'demented Ninga Warrior' time for a sharp exit:001_huh:

You can take the top out, but it will look silly, and flat. Eventually a new leader will form though. As a rough guide, I'd take no more than a 3rd of the height off at the most. Ifhey don't want it any bigger ever try and get a fell and replant with something more suitable.
