colorado spruce tree

Asked June 11, 2017, 5:38 PM EDT

I have a colorado spruce tree in a small garden. I need to keep the spruce from overtaking the garden, as I want to keep it on the small side. When and how do I trim it to reduce it's present size?

This is an example of wrong tree, wrong place. Colorado spruce (unless you are talking about Fat Albert) is a big tree. In the wild it may grow to 75 feet tall but in gardens it usually is 49 feet tall by 16 feet wide. Here is some information: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/choosing-landscape-evergreens/ For a short time you can cut 1/3 off the new growth each year (but not off the leader) but the tree will still get too big for a small area.
