Why are my zucchini dying before maturing?

Why do my zucchini plants have lots of flowers but no fruit?
The pollen may have been too weak to properly fertilise the female flower. While it might look like you have some little fruit developing, it doesn’t continue to grow and will soon turn yellow and die. To encourage natural pollination, you need to attract pollinators into the garden.
