Hi,
I am hoping that your redbud is a Northern Strain; these have been developed to tolerate MN's winters. That said, the redbud is a medium grower so you shouldn't expect to get big very quickly. Here is some info:http://search.schultesgreenhouse.com/12070008/Plant/665/Northern_Strain_Redbud (note that this is not an endorsement of this vendor).
As for the serviceberry, it is also a medium grower. Here is info: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/serviceberry-juneberry/index.html
You might consider fertilizing the trees, so I am providing guidance from the U:http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/tree-fertilization-guide/
