"Honey bees, left to their own devices, are super lazy, and they"ll be like "Yes, I will just hang out on this flower forever,"" Ponisio explains. But upon encountering a wild bee, they"ll fly off to the next flower or plant. That"s particularly beneficial for almond trees, which need pollen from other almond tree varieties to produce nuts. Not every crop will benefit from hedgerows, however; it depends on the farm, the crop and the bee involved.
