Have a fireside and honey crisp tree. Both bloomed just great but set no apples this year. Last year I had a nice crop, not a huge one but good. Both trees are about 10 years old. Why the great blooms but no apples?

The following bulletins address your question. Several things might account for the lack of fruit this year. Maybe you can deduce the reason in your case by a process of elimination.
Fireside blooms mid season and Honeycrisp blooms late mid-season but there should be enough overlap to ensure cross pollination.
