The nectar flow is creeping up. Black Locust trees are waning. Yellow Sweet Clover is blooming across the metro area. Usually yellow sweet clover doesn't produce much nectar in this part of the state. In the Dakota's it is "THE" honey plant.
Basswood trees have dropped their flower pods. The flower pods are not displaying any flowers. I imagine the may bloom early. Normally Basswoods bloom around the first of July. Right now it appears the Basswoods may be blooming a little earlier than usual.
Everything looks like it is going to fire up soon. Supers should be on now. If a beekeeper is still drawing foundation, check the hive every five days to see where the bees are at on drawing comb.
When the top deep is finished or close to it. If it is not heavy with honey, do a reversal and put your supers on. If the top deep is heavy with honey it is too late to do a reversal and run the hive the way it is. Put the supers on.
In general, supers go on two at a time. When drawing foundation put new supers always directly above the brood box. They will draw out the comb better. Check supers weekly. A strong hive with a good nectar flow will be able to draw out, fill and cap a whole honey super in a week. That is about 35 lbs of honey.
All we need now are some 85 degree days.
