Effect of hybrid and corylus americana in the same orchard
I have a small mixed planting of approximately 40 hybrid hazelnuts, and 5 american hazelnuts. The American hazelnuts have been producing for a couple years, while the hybrids are a few years away. Will the different varieties of hazelnuts cross pollinate? I am concerned the American varieties will influence the hybrids to produce smaller nuts. How likely is this? Thanks!
Thank you very much! This is useful information!
