Different bees are attracted to different flowers. I have a flowering plum that is just loaded with bloom. The small wild bees and bumble bees are all over it, yet the honey bees are avoiding it. Go figure. The honey bees are all over the apple trees and dandelions. None of the bees seem attracted to the daffodils and tulips. The honey bees are working the grape hyacinths. Its fun to watch the bees.

I was standing by my apple tree watching them go from blossom to blossom. Little underside packed with pollen. Once my english leather bushes flower I get thousands of bees.
I don't know much about bees, but I know the honeybees spend most of their time on the white clovers all over my lawn. I do my best to avoid mowing when they are around. You might benefit from letting weeds grow in your grass instead of killing them off.
