Went to bed last night in West Michigan with a temp of 4 degrees F. Woke up this morning to -9 degrees F. Yes negative!
Thankfully, last weekend I added a medium super of honey to each colony with a paper plate size piece of candy on the top bars. The clusters were at the tops of the double deeps.
I also added another layer of tar paper wrap since I added height to the stacks. I have a quilt box with almost 3" of cedar shavings on each colony with the telescoping cover over that. The tele covers had ice on each one so I scrapped that off the covers and put a 1/2" piece foam insulation on top of each one.
I'm glad I did all that last week with these temps today and they are continuing for the next few days.
One question though. I have a wine cork sized hole in the front of each medium for a top entrance. With these temps I put a cork in the holes and wrapped over them. Is that the right thing to do? There is plenty of ventilation with the quilt boards on top and I have a few holes in the bottom board too. Once temps get consistently back in the high 20's I will open the holes back up and cut a hole in the wrap.
Does that sound like the right thing to do and at the right temps?
