Answer 1

It is hard to say. It could be environmental reasons such as weather. Maybe there were lots of storms that brought rain for green-up but hindered the pollinators. Or you say the plants/trees have been there for years. Perhaps nutrients have become imbalanced without proper fertilization.
A soil test could indicate those issues. Your local cooperative extension agent can help with that or you can purchase kits in garden centers.
