The amazing thing is that some years he has good pollination. This was not one of those years. The trees looked fine but the nuts were few and far between.
Hoping to help out my friend Larry, I sent an email to Dr Thomas Molnar. Dr Molnar is a filbert breeder at Rutgers University in New Jersey. I asked him if he had any recommendations for pollinators for Grand Traverse.
Dr Molnar answered my questions and sent me a copy of a paper on filbert pollination. While looking at the paper I noticed that the authors of the paper are masters of compressing large amounts of information into compact, easy-to-read charts. I want to share what I saw and try to explain why these charts are so cool.
Finding a good pollinator for Grand Traverse involves finding cultivars that have peak shedding period slightly before, during and slightly after Grand Traverse's peak female receptivity.

To summarize what is cool about this chart is the amount of information that is embedded within it and the author's use of color schemes that intuitively link the information captured in the chart to the biological realities of the filbert plant: Pollen is yellow and pistils are red.
