Tomato blossoms may drop prematurely for several reasons. These include if the plant is, over several days, subjected to high daytime temperatures over 85, or nighttime temps over 70 or below 55. Low or high humidity may also cause it. These conditions all affect pollination. Other factors: lack of pollinators, or too much or too little nitrogen. Diseases or not enough water might also create the problem.
