P.E.I. potato farmers plant flower-filled ‘refuge fields’ for pollinators | CBC News
The mix in Campbell’s field includes seven pollinator species: barley, timothy, alsike clover, yellow blossom sweet clover, bird’s-foot trefoil and phacelia.
The plants flower at different times over the summer, and provide a food source for honeybees, native bee species and other native pollinators.
After the first season, some of the annual plants such as barley will die down, but other plants will come back for a second year, making the fields low maintenance for the farmers.
