I had planted the seeds for my cherry tomatoes in late august in containers. two of the seeds gave me healthy plants of almost five and a half feet. i think they are healthy as i was told that cherry tomato plants only go upto four feet in containers. now my tomatoes flowers are blooming, then some of them have dried off and fallen. but i have seen no sign of fruit appearing. one of them fell off a couple of weeks ago. also i was told that cherry tomatoes flowers fall off in a day or two and the fruit takes it place. but the flowers of my plants stay fresh for a week. is it normal or something is wrong with my plants. can any one help me. i would appreciate it.
here is the picture of my cherry tomato plants.

this is the picture of the blooms and one fallen off flower. (this flower fell off two days ago)
