For the past several years I have been evaluating methods to increase the amount of pollen honeybees gathered off of cranberry bogs. This includes sugar feeding, wave placement, egg laying/brood manipulation, pollen removal, hive locations, hive numbers, QMP, use of complementary nectar rich plants etc. Cranberry pollen is not all that attractive to honey bees and they will go out of their way to collect anything other than cranberry pollen. Some of these methods appear to work some of the time but there is a tremendious variation between hives and locations. Getting good consistent data is hard. Any suggestions? What has worked for other plants which honey bee don't like such as onions or pears? Any work on modifying the attractiveness of the plant to bees other than the use of QMP or other phermone like attractants? What about modifying the mineral nutrition of the plant?
