Newbie question, what is the problem with tomato blossom drop?
Oh, it's generally believed that prolonged exposure to high
temperatures causes tomato blossoms to drop off instead of setting
fruit. However "prolonged exposure" and "high temperatures" seem to be
subjective terms among gardeners as well as among tomatoes, it seems. If
you search the Web, you may find some actual data on the subject.
Off-and-on, blossom drop has been the subject of much discussion on
gardening forums.

In http://ohioline.osu.edu/hyg-fact/1000/1624.html
it was reported that, "Blossom drop can occur in early spring when
daytime temperatures are warm, but night temperatures fall below 55
degrees F as well as in summer, when days are above 90 degrees F and
nights above 76 degrees F."

Have you read differently?
