Like people, bees need a lot of water to survive. Water is an essential, equal in importance to nectar and pollen.
In urban centres, water sources are sometimes hard to come by. Bees may choose a source that is not ideal, such as your watering can… or the neighbour’s pool, for instance!
A dedicated water source can go a long way in mending this situation. Fill it regularly to ensure the bees can count on fresh water.
