We have Heliborus and probably dandelions being worked. Bees had yellow and white pollen coming in. Have lots of daffodils blooming but didn't see any bees near them. The red maples should be blooming now that the weather has warmed up.
South of Atlanta, Georgia.
If you are raising the Temperature to 40º aren't the bees going to starve raising all that brood? Are you talking about doing this when the bees are foraging?
