I have noticed before the bees looking for honey on empty supers I had in my garage. That is a sign of no nectar flow. I thought the flow had stopped.
This week the bees had stopped that behavior and some nectar was coming in again.
Spotted Knapweed is blooming in the area and second cutting of hay has not happened due to dry conditions. The fields are blooming and the bees are taking advantage of it.
Purple Loose Strife is starting to bloom also in the Stillwater area.
I checked my hives last week and added supers to colonies that had honey in the top box.
It is important to stay ahead of the bees as the nectar flow continues....
