Many people where I live have started their own beehives. I’ve heard some of the younger group discussing doing their own pollination. It sounds like a lot of slow & tedious work, but they feel that it is helping them. We no longer have many farmers in the area but I have noticed an upswing in homesteaders who do have small gardens. I have no knowledge as to what the farmers are doing to combat the problem.
I did notice that last summer that the bees were beginning to show back up in my yard. This summer they have doubled in size. I have 5 perennials that haven’t bloomed for the last 5 years, but they did bloom this year. Hadn’t thought about it being the bees but maybe they helped!!!
