My tomatoe plants are looking great, however, not getting many fruits. Blossoms tend to turn brown and fall off if touched.

Extreme temperature often cause flowers to drop. Daytime temperatures above 85F and nighttime temperatures below 55F degrees can both cause this problem. I'm going to take a wild guess and say that high temps, not low ones, are causing your problems! Generally, as temperatures moderate, new flowers and fruit will form. Tomatoes are self pollinating, so bee activity shouldn't be a factor here, like it is in other poor pollination/fruit drop situations. Generally, a light breeze is all it takes to pollinate the flowers. Hope you have a bumper crop!
