Interesting topic. What about other nuts? Specifically, do 
hazelnut/filbert/trazels/etc. need zinc help?

The context: My first crop of hazel family nuts was essentially all 
blanks. Maybe just young bushes, but maybe something else?

so if you don't like the soil, just try 100 feet or so away :-) ]
