Squash Fruits are Rotting on the Vine

Squash plants produce plenty of flowers but the fruit grows an inch or two and then dies. It looks like blossom end rot but is probably lack of pollination.  Squash and related plants including melons and cucumbers have both male and female flowers.  Female flowers have a rudimentary fruit forming at the base of the flower.  It is easy to hand pollinate squash when needed. Pollination is best done in the morning, when high humidity helps to activate the pollen. One male flower can be used to pollinate several female flowers.
