Do all tomato plants produce tomatoes?

I see other people's plants already pumping out little green tomatoes......My plant is 3 feet tall and flowering like crazy....flowers withering to nothing.......

Do all tomato plants produce tomatoes?
Tomato plants require good sunlight and well-draining, moist soil. Did you happen to let it go dry? That'll make the flowers wither. I found the following while searching the web:





"Temperature and Humidity. Daytime temperatures above 90°F and night temperatures above 70°F result in reduced flowering and fruit set. There is considerable evidence that night temperature is the critical factor in setting tomato fruit, the optimal range being 59° to 68°F. With night temperatures much below or above this critical range, fruiting is reduced or absent. Low temperatures reduce the production and viability of pollen. High temperature, especially if accompanied by low humidity and moisture, hinders fruit set through failure in pollination and/or fertilization.





Plant Nutrition. Reduced fruiting may result from either stunted or excessively vigorous vegetative growth. Injury from disease and insects, especially sucking insects such as aphids and thrips, can severely check growth. Inadequate moisture and/or available nitrogen can hinder growth and flower production. Conversely, abundant water and nitrogen can stimulate rapid vegetative growth with low levels of carbohydrates remaining for the normal processes involved in fruit set.





Garden sites located on heavy subsoils are infertile and poorly drained. Gardeners create faulty nutrition by either not applying any fertilizer or by adding too much. In addition, water for irrigation is often not available during times of drought.





Photoperiod (length of day). Although the tomato plant can flower and fruit at any daylength (day neutral plant), fruit set has been shown to be retarded under continuous light. Thus, tomato fruit set may be reduced under the continuous illumination characteristic of some environments."





So there, anything sound familar? Don't forget to fertilize with a fish emulsion or some other fertilizer (containing nitrogen) and designed for tomato plants.
Reply:What Tomato variety are you growing?


Tomatoes have three different growth habits: determinate, indeterminate, and semi-determinate.
Reply:There is a product that can be sprayed on named blossom set that is supposed to help with this problem. I have also heard that Tums can be crushed and dissolved and sprayed on. The calcium is supposed to help set the blossoms. I have never tried the Tums but have used the blossom set, It does seem to help. Hope this helps.
Reply:The flowers need to be pollenated. Do you have only one plant? Perhaps you need more than one? I'm not sure where you are, but it will be several weeks before my tomatoes come out of the greenhouse.
