mgolden:Insulation overhead is very important to prevent condensation and potential dripping onto the cluster. As above, wet bees die.
I'd also encourage some perimeter hive insulation, not just a black wrap. The hive may/will survive without it. However, the warmer interior all winter and into the spring results in large populations and early large populations. I find I need to pull a couple of NUCs in spring, a month apart, to keep the population under control. The main hive barely skips a beat.
The profits from one NUC will far exceed the cost of perimeter insulation. And you only need to buy the insulation once.
Hello BM,I used two inches of rigid foam insulation on all my hives last year. This year I am going to make and use some quilt boxes to try and gauge any difference in their success.
As stated above, ventilation is very important as well.
Spot on. I killed a colony this past winter when we had up and down temps with relatively high humidity. The moisture thawed in the hive, saturated a candy board, and the syrup drenched the bees. My mistake was in not providing enough ventilation. Experience is what you get right after you need it.think about moisture build up when planing. wet bees die in winter.
Hello Biermann. I manage ventilation on my hives last year my ensuring the upper entrance notch was open to allow moisture to escape. I have also used popsicle sticks in each corner to allowHello BM,
Could you give us more info, pictures? How do you manage the ventilation?
