I'm always anxious each year to see how many blossoms appear on the cherry tree, as that's one indicator of the fruit yield for that year. A lot can happen between the budding of the blossoms and harvest of the fruit, but without blossoms, there's no hope for fruit.
I checked the fruit periodically in May and was disappointed that a noticeable number of blossoms did not appear to have been pollinated. I hadn't noticed any bees around the tree this year as in years past, but I wasn't watching closely either. Was I seeing evidence of shrinking bee populations? Evidently the bees did a better job than I expected, as the fruit proliferated over the months of May and June at a rate not a lot slower than the blossoms.
