My Tulip Poplar is just a few days past full bloom and I never saw a honeybee on it. My Catawba tree is just now starting to bloom and I haven't seen a honeybee even approach it. The bumble bees have covered them up though. I'll admit that surprised me about the honeybees but the hive is very active and the majority of the pollen coming back to the hive is yellow. My honey super has 6 full frames I'm guessing primarily from the 6 or 7 acres of yellow clover plus a variety of wild flowers etc. As a new beekeeper I know I have lots to learn but this lesson really surprised me. I guess it's like when momma cooked broccoli for supper. I could eat it but there were always other things on the table I'd eat first.
