Feeding candy during the winter can be done but should be limited to once or twice and then OWN (only when needed). Over feeding can cause problems even in winter. Bees will stop capping honey when the temperature drops to the cluster point. Then they will use those uncapped, unpreocessed or under processed stores faster which may mean a early feeding come spring.
Let the bees work for what they get, monitor, and feed in a emergency. A feeding emergency is:
1. One feeding for a newly acquired swarm or package.
2. In the case of dearth or drought when nectar sources may not be producing due to lack of water.
3. Feeding to apply medication (i.e. Terrimyson for EFB).
4. Lack of stores in the fall or spring.
