My white petunias have been beautiful. However, recently I have noticed that where a flower bloom should be, there is a dead little bud instead. They get full morning sun, but shade in the afternoon. It is in the 90's here in Memphis. I water frequently. Can you help?

It could be an issue with pollination. When the temps get too high, it will interfere with the normal pollination process. Another possibility is water. Even though you regularly water them, in such high temperatures, plants usually require more. Just the soil around them to make sure they are moist but not soggy. Too much water can be just as bad. They might also perk up some with the addition of bone meal too.
