What is the longest you’ve kept bees alive over the winter with only granulated sugar?
One out of my 6 colonies blew through a full deep with only two frames left in the second deep. Yesterday I put a sugar cake in the hive but I am wondering, realistically, if I can keep them alive for 3 more months on just sugar. I am in Pennsylvania.
This is a large colony. The others haven't started on their upper boxes.
