Q.Zucchini Plants Not Producing Fruits
I have a few zucchini plants that are producing lots of flowers, but I’ve come across no fruits. We have plenty of bees and butterflies. I don’t know what the problem is, because almost the same thing is happening to my cucumber plants! Help!

This is typical behavior for a squash plant(and cucumbers). 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.
If you are seeing fruit but they are falling off, this article will help:
