These cultivars will not pollenize each other or any other cultivar. A pollenizer must be provided for these cultivars. If a commercial apple cultivar is used for this purpose, a second pollenizer cultivar should be provided for the first cultivar pollinating a triploid one. Pollen transfer in apples is carried out by several species of insects. Native wild bees, solitary bees such as the bumble bee, flies and other species can play a significant part in pollination.
Honeybees are especially useful in pollination because of their social nature.
Because honeybees live in hives containing thousands of individuals, pollen can be transferred from bee to bee in the hive as well as directly from flower to flower in the field. Some estimates suggest that a large percentage of the pollen exchange that takes place from honeybee activity occurs in the hive rather than in the orchard. Pollenizer arrangements based on hive transfer of pollen make it imperative that high honeybee populations be available each year to accomplish the pollination task. A good colony will satisfactorily pollinate up to 3-4 ha of young trees. As trees grow and fill in their assigned space, increase the number of colonies to 3 hives per ha or more.
