This is my first year growing yellow/summer squash. I am getting a lot of flowers but no fruit. From your article, I did read about hand pollinating, what to look for, how to tell which is a male and which is a female bloom, but my question is: is it possible to have all male flowers on all my plants? I haven't seen one flower with a bulbs under the flower. They all have straight stems under the flower. They were all started from seed.

Generally, they will produce mostly male (non-fruiting) blossoms early in the season and will gradually start to produce more female blossoms as the season progresses. Give it some time and you will see it start fruiting.
