Spring has well and truly sprung and the hives are going from strength to strength, but that brings with it a problem of its own - the swarm. As the colonies become overcrowded, the bees become likely to depart in a swarm with the queen, leaving just a few behind to rear a new queen. It's a natural process, but for the beekeeper it can be a disaster, leaving the hive all but empty with little prospect of a harvest of honey.
Martha discovers methods to control the swarms, including clipping the wings of the queen, but she also meets a natural beekeeper for whom wing clipping is horrifying. When one of her hives swarms, Martha's neighbours leap to the rescue and she harvests the first honey of the year.
