Question: Should I leave supers on for the winter?
Josh Vaisman replies: In areas with long winters a dearth of nectar honeybees rely on their stores of honey to survive. In Colorado, where I live, the dearth begins sometime in October as all the nectar-providing flowers wilt and disappear. Sometimes we don’t see new nectar sources appear until March or April when the dandelions begin to bloom. That means, in a challenging year, my bees might go 5 months or more without natural resources. Whatever honey they have in the hive is what they have to live off. The general rule of thumb in Colorado is, by the end of October, a hive should weigh around 100 pounds.
To help with this scenario some beekeepers, including myself, leave a honey super on the hive over winter. I collect the ‘excess’ honey crop in mid-August but not down to the deeps. If my bees made 4 supers of honey, I only take 3. So, when you see my hives this time of year, you see two deep boxes AND a medium box. In my experience, this allows my bees to keep a larger cluster going into winter and have more food to live off thus helping their winter survival. The downside is, I’m leaving between 25-35 pounds of honey on the hives every year. With four hives, that’s a lot of honey I could have collected for myself.
Some people leave ALL their honey on the hive over winter. So, if the bees make 4 supers all of them stay on over winter. I believe this is excessive and unnecessary. Honey left out over winter will likely crystalize making it difficult to extract the following spring. Furthermore, the cluster of bees needs to move throughout the winter to access food supplies and spreading the food out over a large area like that might actually make it challenging for the bees to get to during particularly long stretches of cold. And, in all likelihood, that much extra honey is far beyond their needs.
