When to reduce the entrance to the hive in the south of North Carolina
My fist year owning the hive. Bees seems to be doing good and have supply of food. Already put the entrance reducer – the bigger hole since the night temperatures are between 50-60. Do i need at some point to use a smaller hole on the entrance reducer or bees will be fine with bigger one in North Carolina? At what average temperature do I need to do this?
