When might supplemental feeding of bee colonies be necessary?

Supplemental feeding of bee colonies is typically most necessary during spring and fall. In spring, bees are often in need of additional resources as they emerge from winter and begin to build up their populations and collect nectar and pollen. However, if there is a delay in flowering or a poor nectar flow, bees may require extra food to support their brood rearing and hive growth at this critical time.

In fall, as the foraging season comes to an end, colonies need to prepare for winter. During this time, if the honey stores are insufficient, bees may require supplemental feeding to ensure they have enough food to survive the winter months. This feeding is crucial because bees need sufficient carbohydrates to maintain their energy levels and to keep the colony warm during the cold season.

While supplemental feeding can be beneficial at other times, such as when honey stores are low or in specific climate conditions, the highest periods of need typically occur in spring and fall as colonies transition between seasons. Thus, the focus on these two seasons is essential for the overall health and survival of the hive.
