Not every beekeeper needs to use pollen patties on their hives. Here in Maine there is an abundant supply of pollen in the fall and our bees are able to store enough for the colony’s purposes through the winter, until fresh pollen is again available in the spring. Unless you’re planning to make early-season splits or raise your own Queens, or if you’re building up in preparation for commercial pollination─you probably don’t need to use pollen patties at all.
On the other hand, if you’re seeking to grow your apiary and make hive increases─then you might be looking to boost bee populations to be able to do that. Feeding bees pollen stimulates brood production: an enriched diet causes nurse bees to secrete lots of royal jelly, which spurs them to prepare cells for eggs and the Queen deposits them. If you time it right you can have a gang-buster colony that you can use to optimize your operation.
