It’s April 2019. I’ve shortened and simplified this post from 2012. Here we go:
I feed my bees patties of pollen supplement or pollen substitute to get the queen laying early in the year so that the colony’s population is at a healthy level when spring arrives. By early in the year, I mean late winter (or February and March in Newfoundland). I usually only give pollen patties to weak colonies, but I’ll give them to strong colonies as well if I plan to make splits from them.
I also feed my nucs pollen patties for first month after they arrive (usually around mid-July in Newfoundland), but that’s not a common practice. Many backyard beekeepers don’t feed their bees pollen patties for any reason at any time of the year. Overfeeding an established colony, whether pollen patties or sugar syrup, can easily create colonies so big that they swarm the first chance they get. And often the bees won’t touch pollen patties once they’re able to bring in real pollen from flowering plants. They chew up the patties and then toss the little bits out of the hive like they would with any kind of debris. So in that case, adding pollen patties creates house-cleaning work for the bees but for no benefit.
Here’s a video of me making some pollen patties — in a way that I probably wouldn’t make them today:
