Pro Winter Patties will provide your colonies with carbohydrates and only a very small amount of protein, so your bees won't be encouraged to start rearing brood too early. As warmer weather approaches, colonies need more protein for brood rearing. So when you are ready for the colony to raise brood, consider switch back to a regular pollen substitute patty that has a much higher proportion of protein in the mix.
The winter patty mix comes in a one gallon bucket, and are not separated by wax paper. Simply spread over your top bars or make your own patties by spreading the mix on wax paper.
