Check out my link to Gary Rueter's Homepage. He has a very good explanation of dividing a colony with nice graphic's.
Also the link to the Univ of MN bee lab for some cool bee posters.
My links are on the right side of this page.
This blog is for beekeepers in Northern climates. I will be describing what I am doing with my bees on a monthly schedule. Copying any text or photos is forbidden except with written authorization of the author.
