Q.Plant flowers but produces no fruit
Planted a Bush Zucchini plant this spring. It flowers but doesn’t produce any fruit. Do I need to have second zucchini plant planted for pollination of the plant?

Zucchini first sends out male blossoms, these will not form fruit.
As the season progresses the female blossoms will form and they will produce the fruit.
You can try hand pollinating if you are not seeing bees in the garden.
Here are a few links for you.
