We have the same problem here with peach trees. In the 70s we lived in a place that had a nice size peach tree. We only got peaches once in the 8 years we lived there.
We will have a killing frost or two in March and April just about the time that we have nice blooms on the trees.
The trees here will blossom, but if the temp stays below 60°F the bees don’t come out to pollinate.................
