I'm in Michigan. I need to open my hives to see if anyone is still buzzing in there and place some pollen patties....what is the recommended temperature for opening a hive? I keep waiting to see the ladies flying about as a sign, but we haven't been above 35 degrees for 2 months. It's supposed to be in the upper 30's this week, but I think that is too cold. My local bee suplier said to put the patties in in Feb, but I haven't been able to. When I feed the patties do I also start feeding syrup?
