We often think of bees as disappearing completely once summer is over, but this isn’t necessarily the case. In winter, certain bees, like honey bees, simply retreat to their hive and try to stay warm – but they don’t hibernate. They join a winter cluster with their companions to ensure they can survive the colder weather. To make it through, these bees must be stocked with enough food to survive the winter months.
Bumble bees, on the other hand, do not form colonies for the winter. Instead, only the queen hibernates until spring while the rest of the colony dies out. The queen will mate and then take refuge in a safe area to spend the winter in. This means she too must have plenty of food to get through the colder period.
For those bees that aren’t hibernating, when the temperature rises a little, they’ll still stick their heads out of the hive to look for some nectar. The problem is that many flowers that have been prevalent throughout spring and summer will have died in the colder weather. This means there’s less food for bees to find, so planting winter flowers that provide that food source for them is important for keeping bees in top shape all winter.
