Colorado Blue Spruce developed two tops
Colorado blue spruce developed two tops last spring. Why did this happen and what can I do to repair this? The tree has been in excellent shape until the new growth started two tops on the tree.

This typically happens if the main trunk's growing tip gets damaged. Other branches on the tree will attempt to take over.
You should inspect the area where the two started competing. You will find either that there is a secondary branch competing with the main trunk or that there are two secondary branches that are competing to replace a topped or irreversibly damaged main trunk.
If it is the first case, you can simply nip or top the secondary branch to stop its growth upward and give the main trunk its edge again.
If it is the second case, there is likely not much you can do because secondary branches will continue to compete for dominance. You may want to have a arborist come look at the tree to determine if any of the secondary branches can take over successfully while maintaining the shape of the tree.
