Previous years, local knotweed were so dense with honeybees it was almost scary but encouraging.Seems like activity didn't last long. This year I seemed to miss the activity although the flowers look like they have been well used.
Goldenrod has lost its color but dandy lions and aster seem to be everywhere.
Bees still seem very active.
Will a cold snap/ frost, stop the nector flow?
Or are other factors more important?
