We're not just talking about planting flowers in flower beds. There must be a variety of flowers that blossom all season long so that bees can feed themselves. This is much more important for the natural pollinators. The agricultural bee or the domestic bee can be fed, like livestock. We have food for bees.
Personally, I'm working on probiotics for bees, an evolving field of research. We're trying to create food products for bees. The bee lives in an agricultural environment or in an area with little flora diversity.
