Hazelnut trees are wind pollinated. In cold weather during the flowering time can destroy flowers and reduce fruit set. The trees are in theory self-fertile meaning the pollen from the male flowers can pollinate and fertilize the female flowers on the same plant. Though the blossoming times of the male and female flowers on the same plant do not always coincide and for this reason, it is recommended to plant 2 or more different tree cultivars to increase the likelihood of pollination occurring. Some cultivars require pollinating partners so research your cultivars well. The pollen germinates as soon as it reaches a receptive flower but the fertilization does not take place for another 4 to 5 months in June.
