Planting mixes of flowers around farm fields helps keep bees healthy

It’s springtime in California, and bees are emerging to feast on flowering fields – acres upon acres of cultivated almonds, oranges and other fruits and nuts that bloom all at once for just a few weeks. Farmers raise these lucrative crops in monoculture fields, each planted with neat, straight rows of a single type of crop.

The agricultural heart of California is the Central Valley, one of the most productive agricultural regions in the world. I recently drove north through the valley on Interstate 5, a 450-mile (724-kilometer) stretch of monoculture farms and agricultural land that runs from Bakersfield to Redding. Flowers were blooming as far as the eye could see. There is so much bloom here that commercial beekeepers truck in over 2 million colonies of bees in spring to ensure that every last flower is pollinated.
