Bill/ David: I am wondering if the green fruits are full sized, or aborted?
pH is often a culprit, true, but I have seen the most dramatic fruit set in
opaca in full blasting sunshine in amenity settings, even though in nature
the tree is well adapted to partial shade.
So...are the green fruits the same size as the red fruits? Is the opaca a
cultivar to the best of your knowledge? Where on the globe are you? Are
there native opaca in your area? Has the soil been tested for pH, etc??
