What should I do during winter?

As winter approaches, you should check the amount of stores to make sure the swarm has enough resources to survive the season. If the stores are low, you can supplement the bees' food using special fondant that can be placed directly on the metal mesh. This way, the bees will collect it while staying inside the nest, without needing to climb up to the honey super. During winter, it's best not to open the hive, or to open it as little as possible: the bees keep the inside of the hive warm through their own movement, and opening it on a very cold day could cause serious problems for the colony.
