A soft light was just beginning to outline the Tejon Hills as Bret Adee counted rows of wizened almond trees under his breath. He placed a small white flag at the end of every 16th row to show his employees where they should place his beehives. Every so often, he fingered the buds on the trees. “It won’t be long,” he said. Mr. Adee (pronounced Ay-Dee) is America’s largest beekeeper, and this is his busy season. Some 92,000 hives had to be deployed before those buds burst into blossom so that his bees could get to the crucial work of pollination.
