Re: Taking a Peek - Winter Feeding
The concern is the moisture being added to the hive interior. It may result in mold issues. Consensus is to feed early in fall so bees have time to dry down the sugar syrup.
Sugar blocks aid in reducing moisture rather than contributing to interior humidity.
A hive interior too moist also contributes to Nosema problems.
Quilt boxes result in a dry interior, so I'd recommend using them if one is feeding syrup over the winter.
