Have quite a few of the multiflower rose bushes down along the bottom and like you said, they are in full bloom.. Don't see many bees on it either.. THe mustard, thistle and clovers are going wild. Thinking the bees are more drawn to that. Plenty of rain, verging on the edge of too much. It has the blooming plants in overdrive, and so are the bees..
I have 26 hives here in the home yard.. I don't like going over 20, but this year none of them are having difficulty bringing the nectar in.. Last year at this time I was starting to feed..
