As a "newbee" I try to read and watch as many videos on bees as I can. One thing I have not been able to find is how do you determine how many hives an area can support? My hives are in zone 8, near a lake, surrounded by trees and no fields. So far my bees are doing what I would like to be doing and that is spending all day around the lake. Any suggestions on how many hives an area can hold?
