Clover all over

We have miles of both dutch and sweet clover this year but no honey being made off of it. I just talked to five other beekeepers totaling just under one thousand hives and know one is producing much of anything. It's odd because I have hives three hours away on a different floral source that are producing a bumper crop.

We always have a lot of clover here in wet years. My bees are working it hard but don't seem to be putting up much.

I believe it requires hot temps to produce lots of nectar.
