Before we can go anywhere else with your question we have to fix the pollenation thing. For some unknown grammatical reason the "e" in pollen changes to an "i" in pollination. Now that we're past that; There are dozens of crops that benefit from honeybee pollination. For some of these crops the growers will pay to have bees "brought in". Alfalfa seed, Almonds, Apples, Cherries, Canola, Blueberries, Cranberries, Melons, Vegetable seeds, and many more. The dates and duration are as diverse as the crops. Some begin as early as February in California and Florida. I would think that you might look into Blueberries in Maine that bloom in May I believe. Good Luck.[/u]
