I feel the same (Ypsilanti, Michigan). This is my first year with 2 hives. One keeps having queen problems, but the other has been growing -- just slowly. I started with a 10 frame deep, drawn out and given to me by a beekeeper. I put the 2nd box on in mid-May, and since then, they have only drawn out 7 or 8 frames there, but nothing in the super I put on in early June.
I'm wondering if they'll ever get up into the super. I was hoping to have a little bit of honey this year.
Oh, and I tried feeding sugar syrup mid-May through first of June, but they didn't touch it and it went bad. Maybe I should have tried again a few weeks later.
I'm still not so knowledgable about the whole nectar flow thing. Flowers seem to be blooming, and the white clover 'weeds' in my yard have been exploding the last 3 weeks or so. I just assumed that was enough.
