… other then lack of pollinators? My peach tree in a full bloom and it is raining second day in a row. Tomorrow is expected to be warm and dry. Did past rain affect pollen on the flowers that could be pollinated tomorrow?
I don’t think so- as long as the pollinators are working I think they’ll get the job done. But the cool weather that often comes with rain might mean that honey bees, at least, are less active. Some other insects, such as mason bees, work at lower temps.
