Soil temperature and blossom drop?

They are reasonably vigorous. Certainly there are enough healthy leaves to support more fruit than they are holding.

They did this last year, too, and then started to set fruit better once it cooled down a bit -- hence my focus on temperature. I just find it odd, given that I live in an area with a very mild climate (e.g., yesterday's highs and lows were 74 and 55 degrees F). But the roots and flowers themselves do experience higher temperatures, due to being in pots and sitting on a concrete driveway.
