I have a few backyard hives in an old settled neighborhood by the bay. When I first decided to keep bees, I was worried that there might not be enough pasture for bees here. So I asked one of the local bee club gurus about it. He's a sideliner with yards 30 miles north of the coast in a rural area. He said, "Don't worry. You'll make twice as much honey per hive as I do."
Is this a general truth, or does it just apply to our semitropical area?
