Answer: It doesn't sound as though the flowers are being pollinated. There are many causes for this - daytime temperatures above 90F or below 55F, or nightime temperatures in the mid-70's can all cause sterile pollen. High temperatures, low light, too much Nitrogen, low humidity, or low temperatures may cause irregular flower or pollen development, all of which can affect fruit production. It's early in the season - my bet is that you'll be harvesting okra in a few short weeks.
